Introduction

Prerequisites, returning a variable from a controller, setting variables in laravel blade template.

The Blade templating engine has been a real game-changer for me. Blade makes it working with PHP and HTML a breeze. It allows you to use plain PHP code directly in your template.

In most cases, you will pass your variables from your controller to your Blade views, but you might want to set a variable directly in your Blade view in some cases.

In this tutorial, you will learn how to set a variable in your Laravel Blade Template directly !

Before you start, you would need to have a Laravel application up and running.

I will be using a DigitalOcean Ubuntu Droplet for this demo. If you wish, you can use my affiliate code to get free $100 DigitalOcean credit to spin up your own servers!

If you do not have that yet, you can follow the steps from this tutorial on how to do that:

  • How to Install Laravel on DigitalOcean with 1-Click

Or you could use this awesome script to do the installation:

You could pass variables to the view helper function directly from your controller or route in some cases.

The syntax is the following:

The above will return the dashboard.blade.php view, and a variable called $name with the value of Bobby will be available so you could call it like this in your view:

By default, this will escape all HTML tags, but in case that you needed to render HTML tags, you could follow the steps on how to do that here:

  • How To Display HTML Tags In Blade With Laravel

Alternatively, you could use the compact helper function to pass multiple variables from your controller to your view:

Now that we've got this covered, here is how you could define a variable directly in your Blade template rather than passing it from your controller.

As you could use plain PHP directly in your Blade template, all that you need to do in order to define a new variable is to use the following syntax in your view:

Thanks to the @php directive, you could actually write pure PHP directly in your view. Even though that, it would probably be better to keep any complex logic in your controller. Still, in some cases, it is super handy to have this as an option.

Alternatively, you could actually use general PHP opening and closing tags, but I prefer to stick to the Blade PHP block instead:

Set variables in a Laravel Blade Template? [SOLVED]

Laravel is known for its simplicity and elegance in building web applications. One of the key components of Laravel is its powerful templating engine called Blade. Blade templates provide a convenient way to separate the presentation logic from the application's backend code.

When working with Blade templates , it's often necessary to set variables that will be used to render dynamic content or control the behavior of the template. Whether you need to pass data from the controller to the view or perform calculations within the template itself, knowing how to set variables in a Laravel blade template is essential.

This blog post explores different techniques for setting variables in a Laravel Blade template. We'll cover various methods, including inline variable assignment, using the "with" method, leveraging the "compact" function, and utilizing the "@php" directive.

So, let's dive in and discover the different approaches to set variables in Laravel Blade templates that will enhance your productivity and help you build robust and dynamic web applications.

Using Inline Variable Assignment

Inline variable assignment in Laravel Blade templates provides a convenient and concise way to set variables directly within the template itself. This method is especially useful when you need to assign a simple value or perform a basic calculation without the need for complex logic.

To set a variable using inline assignment in a Blade template, you can use the following syntax:

Let's break down the syntax:

  • The @php directive indicates that you're entering PHP code within the Blade template.
  • $variableName represents the name you want to give to your variable. Choose a meaningful and descriptive name to ensure clarity.
  • = is the assignment operator that assigns a value to the variable.
  • value is the actual value you want to assign to the variable. It can be a string, number, boolean, or the result of a simple calculation.

Here's an example to illustrate the usage of inline variable assignment in a Laravel Blade template:

In this example, we set three variables: $pageTitle with a string value, $numberOfItems with an integer value, and $totalPrice with the result of multiplying $numberOfItems by the price per item. Later, we use these variables within the HTML markup using double curly braces {{ }} to output their values.

How to Set Variables in a Laravel Blade Template

Using the "with" method

the "with" method allows you to set variables and pass data from the controller to the view. This method is particularly useful when you want to assign multiple variables or when you need to pass data from the backend to the frontend.

To set variables in a Laravel Blade template using the "with" method, follow these steps:

In your controller, use the with method on the view function when returning the view. The with method accepts an array where the keys represent the variable names and the values represent the data to be assigned to those variables. For example:

In your Blade template, you can directly access the variables using their assigned names. For example:

By using the "with" method, you can easily pass data from the controller to the view and access it within the Blade template. This promotes separation of concerns and allows for more flexible and maintainable code.

Here's an example to illustrate the usage of the "with" method in a Laravel Blade template:

In this example, we assign the variables $pageTitle , $numberOfItems , and $totalPrice in the controller using the "with" method. Then, we access and display these variables in the Blade template using the double curly brace notation {{ }} .

Using the "compact" function

the "compact" function provides a convenient way to set variables by compacting them from the controller and passing them directly to the view. This method is particularly useful when you want to pass multiple variables in a concise manner.

To set variables in a Laravel Blade template using the "compact" function, follow these steps:

In your controller, define the variables you want to pass to the view.

Return the view using the "compact" function, passing the variable names as arguments.

In your Blade template, you can directly access the variables using their assigned names.

By using the "compact" function, you can pass multiple variables from the controller to the view without explicitly creating an array or using the "with" method.

Here's an example to illustrate the usage of the "compact" function in a Laravel Blade template:

In this example, we define the variables $pageTitle , $numberOfItems , and $totalPrice in the controller. Then, we pass these variables to the view using the "compact" function. Finally, we access and display these variables in the Blade template using the double curly brace notation {{ }} .

Set variables in a Laravel Blade Template? [SOLVED]

Setting variables in Laravel Blade templates allows you to create dynamic and interactive web applications. Whether you prefer inline variable assignment, the with method, or the compact function, each method has advantages and can suit different scenarios. Experiment with these techniques, consider the specific requirements of your project and choose the approach that best fits your needs.

Now that you have a solid understanding of how to set variables in Laravel Blade templates, go ahead and unleash the power of Blade to create stunning and dynamic user interfaces for your Laravel applications .

Blade Templates

Supercharging blade with livewire, html entity encoding, blade and javascript frameworks, if statements, switch statements, the loop variable.

  • Conditional Classes

Additional Attributes

Including subviews, the @once directive, rendering components, passing data to components, component attributes, reserved keywords, inline component views, dynamic components, manually registering components, anonymous index components, data properties / attributes, accessing parent data.

  • Anonymous Components Paths

Layouts Using Components

Layouts using template inheritance, method field, validation errors, service injection, rendering inline blade templates, rendering blade fragments, custom echo handlers, custom if statements, introduction.

Blade is the simple, yet powerful templating engine that is included with Laravel. Unlike some PHP templating engines, Blade does not restrict you from using plain PHP code in your templates. In fact, all Blade templates are compiled into plain PHP code and cached until they are modified, meaning Blade adds essentially zero overhead to your application. Blade template files use the .blade.php file extension and are typically stored in the resources/views directory.

Blade views may be returned from routes or controllers using the global view helper. Of course, as mentioned in the documentation on views , data may be passed to the Blade view using the view helper's second argument:

Want to take your Blade templates to the next level and build dynamic interfaces with ease? Check out Laravel Livewire . Livewire allows you to write Blade components that are augmented with dynamic functionality that would typically only be possible via frontend frameworks like React or Vue, providing a great approach to building modern, reactive frontends without the complexities, client-side rendering, or build steps of many JavaScript frameworks.

Displaying Data

You may display data that is passed to your Blade views by wrapping the variable in curly braces. For example, given the following route:

You may display the contents of the name variable like so:

[!NOTE] Blade's {{ }} echo statements are automatically sent through PHP's htmlspecialchars function to prevent XSS attacks.

You are not limited to displaying the contents of the variables passed to the view. You may also echo the results of any PHP function. In fact, you can put any PHP code you wish inside of a Blade echo statement:

By default, Blade (and the Laravel e function) will double encode HTML entities. If you would like to disable double encoding, call the Blade::withoutDoubleEncoding method from the boot method of your AppServiceProvider :

Displaying Unescaped Data

By default, Blade {{ }} statements are automatically sent through PHP's htmlspecialchars function to prevent XSS attacks. If you do not want your data to be escaped, you may use the following syntax:

[!WARNING] Be very careful when echoing content that is supplied by users of your application. You should typically use the escaped, double curly brace syntax to prevent XSS attacks when displaying user supplied data.

Since many JavaScript frameworks also use "curly" braces to indicate a given expression should be displayed in the browser, you may use the @ symbol to inform the Blade rendering engine an expression should remain untouched. For example:

In this example, the @ symbol will be removed by Blade; however, {{ name }} expression will remain untouched by the Blade engine, allowing it to be rendered by your JavaScript framework.

The @ symbol may also be used to escape Blade directives:

Rendering JSON

Sometimes you may pass an array to your view with the intention of rendering it as JSON in order to initialize a JavaScript variable. For example:

However, instead of manually calling json_encode , you may use the Illuminate\Support\Js::from method directive. The from method accepts the same arguments as PHP's json_encode function; however, it will ensure that the resulting JSON is properly escaped for inclusion within HTML quotes. The from method will return a string JSON.parse JavaScript statement that will convert the given object or array into a valid JavaScript object:

The latest versions of the Laravel application skeleton include a Js facade, which provides convenient access to this functionality within your Blade templates:

[!WARNING] You should only use the Js::from method to render existing variables as JSON. The Blade templating is based on regular expressions and attempts to pass a complex expression to the directive may cause unexpected failures.

The @verbatim Directive

If you are displaying JavaScript variables in a large portion of your template, you may wrap the HTML in the @verbatim directive so that you do not have to prefix each Blade echo statement with an @ symbol:

Blade Directives

In addition to template inheritance and displaying data, Blade also provides convenient shortcuts for common PHP control structures, such as conditional statements and loops. These shortcuts provide a very clean, terse way of working with PHP control structures while also remaining familiar to their PHP counterparts.

You may construct if statements using the @if , @elseif , @else , and @endif directives. These directives function identically to their PHP counterparts:

For convenience, Blade also provides an @unless directive:

In addition to the conditional directives already discussed, the @isset and @empty directives may be used as convenient shortcuts for their respective PHP functions:

Authentication Directives

The @auth and @guest directives may be used to quickly determine if the current user is authenticated or is a guest:

If needed, you may specify the authentication guard that should be checked when using the @auth and @guest directives:

Environment Directives

You may check if the application is running in the production environment using the @production directive:

Or, you may determine if the application is running in a specific environment using the @env directive:

Section Directives

You may determine if a template inheritance section has content using the @hasSection directive:

You may use the sectionMissing directive to determine if a section does not have content:

Session Directives

The @session directive may be used to determine if a session value exists. If the session value exists, the template contents within the @session and @endsession directives will be evaluated. Within the @session directive's contents, you may echo the $value variable to display the session value:

Switch statements can be constructed using the @switch , @case , @break , @default and @endswitch directives:

In addition to conditional statements, Blade provides simple directives for working with PHP's loop structures. Again, each of these directives functions identically to their PHP counterparts:

[!NOTE] While iterating through a foreach loop, you may use the loop variable to gain valuable information about the loop, such as whether you are in the first or last iteration through the loop.

When using loops you may also skip the current iteration or end the loop using the @continue and @break directives:

You may also include the continuation or break condition within the directive declaration:

While iterating through a foreach loop, a $loop variable will be available inside of your loop. This variable provides access to some useful bits of information such as the current loop index and whether this is the first or last iteration through the loop:

If you are in a nested loop, you may access the parent loop's $loop variable via the parent property:

The $loop variable also contains a variety of other useful properties:

Conditional Classes & Styles

The @class directive conditionally compiles a CSS class string. The directive accepts an array of classes where the array key contains the class or classes you wish to add, while the value is a boolean expression. If the array element has a numeric key, it will always be included in the rendered class list:

Likewise, the @style directive may be used to conditionally add inline CSS styles to an HTML element:

For convenience, you may use the @checked directive to easily indicate if a given HTML checkbox input is "checked". This directive will echo checked if the provided condition evaluates to true :

Likewise, the @selected directive may be used to indicate if a given select option should be "selected":

Additionally, the @disabled directive may be used to indicate if a given element should be "disabled":

Moreover, the @readonly directive may be used to indicate if a given element should be "readonly":

In addition, the @required directive may be used to indicate if a given element should be "required":

[!NOTE] While you're free to use the @include directive, Blade components provide similar functionality and offer several benefits over the @include directive such as data and attribute binding.

Blade's @include directive allows you to include a Blade view from within another view. All variables that are available to the parent view will be made available to the included view:

Even though the included view will inherit all data available in the parent view, you may also pass an array of additional data that should be made available to the included view:

If you attempt to @include a view which does not exist, Laravel will throw an error. If you would like to include a view that may or may not be present, you should use the @includeIf directive:

If you would like to @include a view if a given boolean expression evaluates to true or false , you may use the @includeWhen and @includeUnless directives:

To include the first view that exists from a given array of views, you may use the includeFirst directive:

[!WARNING] You should avoid using the __DIR__ and __FILE__ constants in your Blade views, since they will refer to the location of the cached, compiled view.

Rendering Views for Collections

You may combine loops and includes into one line with Blade's @each directive:

The @each directive's first argument is the view to render for each element in the array or collection. The second argument is the array or collection you wish to iterate over, while the third argument is the variable name that will be assigned to the current iteration within the view. So, for example, if you are iterating over an array of jobs , typically you will want to access each job as a job variable within the view. The array key for the current iteration will be available as the key variable within the view.

You may also pass a fourth argument to the @each directive. This argument determines the view that will be rendered if the given array is empty.

[!WARNING] Views rendered via @each do not inherit the variables from the parent view. If the child view requires these variables, you should use the @foreach and @include directives instead.

The @once directive allows you to define a portion of the template that will only be evaluated once per rendering cycle. This may be useful for pushing a given piece of JavaScript into the page's header using stacks . For example, if you are rendering a given component within a loop, you may wish to only push the JavaScript to the header the first time the component is rendered:

Since the @once directive is often used in conjunction with the @push or @prepend directives, the @pushOnce and @prependOnce directives are available for your convenience:

In some situations, it's useful to embed PHP code into your views. You can use the Blade @php directive to execute a block of plain PHP within your template:

Or, if you only need to use PHP to import a class, you may use the @use directive:

A second argument may be provided to the @use directive to alias the imported class:

Blade also allows you to define comments in your views. However, unlike HTML comments, Blade comments are not included in the HTML returned by your application:

Components and slots provide similar benefits to sections, layouts, and includes; however, some may find the mental model of components and slots easier to understand. There are two approaches to writing components: class based components and anonymous components.

To create a class based component, you may use the make:component Artisan command. To illustrate how to use components, we will create a simple Alert component. The make:component command will place the component in the app/View/Components directory:

The make:component command will also create a view template for the component. The view will be placed in the resources/views/components directory. When writing components for your own application, components are automatically discovered within the app/View/Components directory and resources/views/components directory, so no further component registration is typically required.

You may also create components within subdirectories:

The command above will create an Input component in the app/View/Components/Forms directory and the view will be placed in the resources/views/components/forms directory.

If you would like to create an anonymous component (a component with only a Blade template and no class), you may use the --view flag when invoking the make:component command:

The command above will create a Blade file at resources/views/components/forms/input.blade.php which can be rendered as a component via <x-forms.input /> .

Manually Registering Package Components

When writing components for your own application, components are automatically discovered within the app/View/Components directory and resources/views/components directory.

However, if you are building a package that utilizes Blade components, you will need to manually register your component class and its HTML tag alias. You should typically register your components in the boot method of your package's service provider:

Once your component has been registered, it may be rendered using its tag alias:

Alternatively, you may use the componentNamespace method to autoload component classes by convention. For example, a Nightshade package might have Calendar and ColorPicker components that reside within the Package\Views\Components namespace:

This will allow the usage of package components by their vendor namespace using the package-name:: syntax:

Blade will automatically detect the class that's linked to this component by pascal-casing the component name. Subdirectories are also supported using "dot" notation.

To display a component, you may use a Blade component tag within one of your Blade templates. Blade component tags start with the string x- followed by the kebab case name of the component class:

If the component class is nested deeper within the app/View/Components directory, you may use the . character to indicate directory nesting. For example, if we assume a component is located at app/View/Components/Inputs/Button.php , we may render it like so:

If you would like to conditionally render your component, you may define a shouldRender method on your component class. If the shouldRender method returns false the component will not be rendered:

You may pass data to Blade components using HTML attributes. Hard-coded, primitive values may be passed to the component using simple HTML attribute strings. PHP expressions and variables should be passed to the component via attributes that use the : character as a prefix:

You should define all of the component's data attributes in its class constructor. All public properties on a component will automatically be made available to the component's view. It is not necessary to pass the data to the view from the component's render method:

When your component is rendered, you may display the contents of your component's public variables by echoing the variables by name:

Component constructor arguments should be specified using camelCase , while kebab-case should be used when referencing the argument names in your HTML attributes. For example, given the following component constructor:

The $alertType argument may be provided to the component like so:

Short Attribute Syntax

When passing attributes to components, you may also use a "short attribute" syntax. This is often convenient since attribute names frequently match the variable names they correspond to:

Escaping Attribute Rendering

Since some JavaScript frameworks such as Alpine.js also use colon-prefixed attributes, you may use a double colon ( :: ) prefix to inform Blade that the attribute is not a PHP expression. For example, given the following component:

The following HTML will be rendered by Blade:

Component Methods

In addition to public variables being available to your component template, any public methods on the component may be invoked. For example, imagine a component that has an isSelected method:

You may execute this method from your component template by invoking the variable matching the name of the method:

Accessing Attributes and Slots Within Component Classes

Blade components also allow you to access the component name, attributes, and slot inside the class's render method. However, in order to access this data, you should return a closure from your component's render method. The closure will receive a $data array as its only argument. This array will contain several elements that provide information about the component:

The componentName is equal to the name used in the HTML tag after the x- prefix. So <x-alert /> 's componentName will be alert . The attributes element will contain all of the attributes that were present on the HTML tag. The slot element is an Illuminate\Support\HtmlString instance with the contents of the component's slot.

The closure should return a string. If the returned string corresponds to an existing view, that view will be rendered; otherwise, the returned string will be evaluated as an inline Blade view.

Additional Dependencies

If your component requires dependencies from Laravel's service container , you may list them before any of the component's data attributes and they will automatically be injected by the container:

Hiding Attributes / Methods

If you would like to prevent some public methods or properties from being exposed as variables to your component template, you may add them to an $except array property on your component:

We've already examined how to pass data attributes to a component; however, sometimes you may need to specify additional HTML attributes, such as class , that are not part of the data required for a component to function. Typically, you want to pass these additional attributes down to the root element of the component template. For example, imagine we want to render an alert component like so:

All of the attributes that are not part of the component's constructor will automatically be added to the component's "attribute bag". This attribute bag is automatically made available to the component via the $attributes variable. All of the attributes may be rendered within the component by echoing this variable:

[!WARNING] Using directives such as @env within component tags is not supported at this time. For example, <x-alert :live="@env('production')"/> will not be compiled.

Default / Merged Attributes

Sometimes you may need to specify default values for attributes or merge additional values into some of the component's attributes. To accomplish this, you may use the attribute bag's merge method. This method is particularly useful for defining a set of default CSS classes that should always be applied to a component:

If we assume this component is utilized like so:

The final, rendered HTML of the component will appear like the following:

Conditionally Merge Classes

Sometimes you may wish to merge classes if a given condition is true . You can accomplish this via the class method, which accepts an array of classes where the array key contains the class or classes you wish to add, while the value is a boolean expression. If the array element has a numeric key, it will always be included in the rendered class list:

If you need to merge other attributes onto your component, you can chain the merge method onto the class method:

[!NOTE] If you need to conditionally compile classes on other HTML elements that shouldn't receive merged attributes, you can use the @class directive .

Non-Class Attribute Merging

When merging attributes that are not class attributes, the values provided to the merge method will be considered the "default" values of the attribute. However, unlike the class attribute, these attributes will not be merged with injected attribute values. Instead, they will be overwritten. For example, a button component's implementation may look like the following:

To render the button component with a custom type , it may be specified when consuming the component. If no type is specified, the button type will be used:

The rendered HTML of the button component in this example would be:

If you would like an attribute other than class to have its default value and injected values joined together, you may use the prepends method. In this example, the data-controller attribute will always begin with profile-controller and any additional injected data-controller values will be placed after this default value:

Retrieving and Filtering Attributes

You may filter attributes using the filter method. This method accepts a closure which should return true if you wish to retain the attribute in the attribute bag:

For convenience, you may use the whereStartsWith method to retrieve all attributes whose keys begin with a given string:

Conversely, the whereDoesntStartWith method may be used to exclude all attributes whose keys begin with a given string:

Using the first method, you may render the first attribute in a given attribute bag:

If you would like to check if an attribute is present on the component, you may use the has method. This method accepts the attribute name as its only argument and returns a boolean indicating whether or not the attribute is present:

If an array is passed to the has method, the method will determine if all of the given attributes are present on the component:

The hasAny method may be used to determine if any of the given attributes are present on the component:

You may retrieve a specific attribute's value using the get method:

By default, some keywords are reserved for Blade's internal use in order to render components. The following keywords cannot be defined as public properties or method names within your components:

  • resolveView
  • shouldRender
  • withAttributes

You will often need to pass additional content to your component via "slots". Component slots are rendered by echoing the $slot variable. To explore this concept, let's imagine that an alert component has the following markup:

We may pass content to the slot by injecting content into the component:

Sometimes a component may need to render multiple different slots in different locations within the component. Let's modify our alert component to allow for the injection of a "title" slot:

You may define the content of the named slot using the x-slot tag. Any content not within an explicit x-slot tag will be passed to the component in the $slot variable:

You may invoke a slot's isEmpty method to determine if the slot contains content:

Additionally, the hasActualContent method may be used to determine if the slot contains any "actual" content that is not an HTML comment:

Scoped Slots

If you have used a JavaScript framework such as Vue, you may be familiar with "scoped slots", which allow you to access data or methods from the component within your slot. You may achieve similar behavior in Laravel by defining public methods or properties on your component and accessing the component within your slot via the $component variable. In this example, we will assume that the x-alert component has a public formatAlert method defined on its component class:

Slot Attributes

Like Blade components, you may assign additional attributes to slots such as CSS class names:

To interact with slot attributes, you may access the attributes property of the slot's variable. For more information on how to interact with attributes, please consult the documentation on component attributes :

For very small components, it may feel cumbersome to manage both the component class and the component's view template. For this reason, you may return the component's markup directly from the render method:

Generating Inline View Components

To create a component that renders an inline view, you may use the inline option when executing the make:component command:

Sometimes you may need to render a component but not know which component should be rendered until runtime. In this situation, you may use Laravel's built-in dynamic-component component to render the component based on a runtime value or variable:

[!WARNING] The following documentation on manually registering components is primarily applicable to those who are writing Laravel packages that include view components. If you are not writing a package, this portion of the component documentation may not be relevant to you.

However, if you are building a package that utilizes Blade components or placing components in non-conventional directories, you will need to manually register your component class and its HTML tag alias so that Laravel knows where to find the component. You should typically register your components in the boot method of your package's service provider:

Autoloading Package Components

Anonymous components.

Similar to inline components, anonymous components provide a mechanism for managing a component via a single file. However, anonymous components utilize a single view file and have no associated class. To define an anonymous component, you only need to place a Blade template within your resources/views/components directory. For example, assuming you have defined a component at resources/views/components/alert.blade.php , you may simply render it like so:

You may use the . character to indicate if a component is nested deeper inside the components directory. For example, assuming the component is defined at resources/views/components/inputs/button.blade.php , you may render it like so:

Sometimes, when a component is made up of many Blade templates, you may wish to group the given component's templates within a single directory. For example, imagine an "accordion" component with the following directory structure:

This directory structure allows you to render the accordion component and its item like so:

However, in order to render the accordion component via x-accordion , we were forced to place the "index" accordion component template in the resources/views/components directory instead of nesting it within the accordion directory with the other accordion related templates.

Thankfully, Blade allows you to place an index.blade.php file within a component's template directory. When an index.blade.php template exists for the component, it will be rendered as the "root" node of the component. So, we can continue to use the same Blade syntax given in the example above; however, we will adjust our directory structure like so:

Since anonymous components do not have any associated class, you may wonder how you may differentiate which data should be passed to the component as variables and which attributes should be placed in the component's attribute bag .

You may specify which attributes should be considered data variables using the @props directive at the top of your component's Blade template. All other attributes on the component will be available via the component's attribute bag. If you wish to give a data variable a default value, you may specify the variable's name as the array key and the default value as the array value:

Given the component definition above, we may render the component like so:

Sometimes you may want to access data from a parent component inside a child component. In these cases, you may use the @aware directive. For example, imagine we are building a complex menu component consisting of a parent <x-menu> and child <x-menu.item> :

The <x-menu> component may have an implementation like the following:

Because the color prop was only passed into the parent ( <x-menu> ), it won't be available inside <x-menu.item> . However, if we use the @aware directive, we can make it available inside <x-menu.item> as well:

[!WARNING] The @aware directive can not access parent data that is not explicitly passed to the parent component via HTML attributes. Default @props values that are not explicitly passed to the parent component can not be accessed by the @aware directive.

Anonymous Component Paths

As previously discussed, anonymous components are typically defined by placing a Blade template within your resources/views/components directory. However, you may occasionally want to register other anonymous component paths with Laravel in addition to the default path.

The anonymousComponentPath method accepts the "path" to the anonymous component location as its first argument and an optional "namespace" that components should be placed under as its second argument. Typically, this method should be called from the boot method of one of your application's service providers :

When component paths are registered without a specified prefix as in the example above, they may be rendered in your Blade components without a corresponding prefix as well. For example, if a panel.blade.php component exists in the path registered above, it may be rendered like so:

Prefix "namespaces" may be provided as the second argument to the anonymousComponentPath method:

When a prefix is provided, components within that "namespace" may be rendered by prefixing to the component's namespace to the component name when the component is rendered:

Building Layouts

Most web applications maintain the same general layout across various pages. It would be incredibly cumbersome and hard to maintain our application if we had to repeat the entire layout HTML in every view we create. Thankfully, it's convenient to define this layout as a single Blade component and then use it throughout our application.

Defining the Layout Component

For example, imagine we are building a "todo" list application. We might define a layout component that looks like the following:

Applying the Layout Component

Once the layout component has been defined, we may create a Blade view that utilizes the component. In this example, we will define a simple view that displays our task list:

Remember, content that is injected into a component will be supplied to the default $slot variable within our layout component. As you may have noticed, our layout also respects a $title slot if one is provided; otherwise, a default title is shown. We may inject a custom title from our task list view using the standard slot syntax discussed in the component documentation :

Now that we have defined our layout and task list views, we just need to return the task view from a route:

Defining a Layout

Layouts may also be created via "template inheritance". This was the primary way of building applications prior to the introduction of components .

To get started, let's take a look at a simple example. First, we will examine a page layout. Since most web applications maintain the same general layout across various pages, it's convenient to define this layout as a single Blade view:

As you can see, this file contains typical HTML mark-up. However, take note of the @section and @yield directives. The @section directive, as the name implies, defines a section of content, while the @yield directive is used to display the contents of a given section.

Now that we have defined a layout for our application, let's define a child page that inherits the layout.

Extending a Layout

When defining a child view, use the @extends Blade directive to specify which layout the child view should "inherit". Views which extend a Blade layout may inject content into the layout's sections using @section directives. Remember, as seen in the example above, the contents of these sections will be displayed in the layout using @yield :

In this example, the sidebar section is utilizing the @parent directive to append (rather than overwriting) content to the layout's sidebar. The @parent directive will be replaced by the content of the layout when the view is rendered.

[!NOTE] Contrary to the previous example, this sidebar section ends with @endsection instead of @show . The @endsection directive will only define a section while @show will define and immediately yield the section.

The @yield directive also accepts a default value as its second parameter. This value will be rendered if the section being yielded is undefined:

Anytime you define an HTML form in your application, you should include a hidden CSRF token field in the form so that the CSRF protection middleware can validate the request. You may use the @csrf Blade directive to generate the token field:

Since HTML forms can't make PUT , PATCH , or DELETE requests, you will need to add a hidden _method field to spoof these HTTP verbs. The @method Blade directive can create this field for you:

The @error directive may be used to quickly check if validation error messages exist for a given attribute. Within an @error directive, you may echo the $message variable to display the error message:

Since the @error directive compiles to an "if" statement, you may use the @else directive to render content when there is not an error for an attribute:

You may pass the name of a specific error bag as the second parameter to the @error directive to retrieve validation error messages on pages containing multiple forms:

Blade allows you to push to named stacks which can be rendered somewhere else in another view or layout. This can be particularly useful for specifying any JavaScript libraries required by your child views:

If you would like to @push content if a given boolean expression evaluates to true , you may use the @pushIf directive:

You may push to a stack as many times as needed. To render the complete stack contents, pass the name of the stack to the @stack directive:

If you would like to prepend content onto the beginning of a stack, you should use the @prepend directive:

The @inject directive may be used to retrieve a service from the Laravel service container . The first argument passed to @inject is the name of the variable the service will be placed into, while the second argument is the class or interface name of the service you wish to resolve:

Sometimes you may need to transform a raw Blade template string into valid HTML. You may accomplish this using the render method provided by the Blade facade. The render method accepts the Blade template string and an optional array of data to provide to the template:

Laravel renders inline Blade templates by writing them to the storage/framework/views directory. If you would like Laravel to remove these temporary files after rendering the Blade template, you may provide the deleteCachedView argument to the method:

When using frontend frameworks such as Turbo and htmx , you may occasionally need to only return a portion of a Blade template within your HTTP response. Blade "fragments" allow you to do just that. To get started, place a portion of your Blade template within @fragment and @endfragment directives:

Then, when rendering the view that utilizes this template, you may invoke the fragment method to specify that only the specified fragment should be included in the outgoing HTTP response:

The fragmentIf method allows you to conditionally return a fragment of a view based on a given condition. Otherwise, the entire view will be returned:

The fragments and fragmentsIf methods allow you to return multiple view fragments in the response. The fragments will be concatenated together:

Extending Blade

Blade allows you to define your own custom directives using the directive method. When the Blade compiler encounters the custom directive, it will call the provided callback with the expression that the directive contains.

The following example creates a @datetime($var) directive which formats a given $var , which should be an instance of DateTime :

As you can see, we will chain the format method onto whatever expression is passed into the directive. So, in this example, the final PHP generated by this directive will be:

[!WARNING] After updating the logic of a Blade directive, you will need to delete all of the cached Blade views. The cached Blade views may be removed using the view:clear Artisan command.

If you attempt to "echo" an object using Blade, the object's __toString method will be invoked. The __toString method is one of PHP's built-in "magic methods". However, sometimes you may not have control over the __toString method of a given class, such as when the class that you are interacting with belongs to a third-party library.

In these cases, Blade allows you to register a custom echo handler for that particular type of object. To accomplish this, you should invoke Blade's stringable method. The stringable method accepts a closure. This closure should type-hint the type of object that it is responsible for rendering. Typically, the stringable method should be invoked within the boot method of your application's AppServiceProvider class:

Once your custom echo handler has been defined, you may simply echo the object in your Blade template:

Programming a custom directive is sometimes more complex than necessary when defining simple, custom conditional statements. For that reason, Blade provides a Blade::if method which allows you to quickly define custom conditional directives using closures. For example, let's define a custom conditional that checks the configured default "disk" for the application. We may do this in the boot method of our AppServiceProvider :

Once the custom conditional has been defined, you can use it within your templates:

Laravel 10: How to Set Variables in a Laravel Blade Template

Laravel 10: How to Set Variables in a Laravel Blade Template

Today we are going to learn Laravel 10: How to Set Variables in a Laravel Blade Template . Laravel is a popular PHP framework known for its elegant syntax and powerful features.

One of its key features is the Blade templating engine, which allows developers to build dynamic and reusable templates.

In this blog post, we will explore how to set variables in a Laravel Blade template, specifically focusing on the latest version, Laravel 10.

Also Read : How to use multiple databases in Laravel

Understanding Blade Templates:

Before we dive into setting variables in a Laravel Blade template, let’s briefly discuss what Blade templates are. Blade is a simple yet powerful templating engine provided by Laravel. It allows developers to write clean and readable code by separating HTML markup from PHP logic. Blade templates have a “.blade.php” file extension and are stored in the resources/views directory by default.

1. Passing Variables from Controller to View:

In Laravel, you can pass variables from your controller to your Blade template using the with method or by compacting an array of variables. Let’s see how it’s done.

Using the with Method:

In this example, we pass a variable called $message to the index view using the with method. Inside the Blade template, you can access this variable using the following syntax:

Using the Compact Function:

In this case, we use the compact function to create an array of variables ( $message and $title ) and pass them to the index view. The variables can then be accessed in the Blade template as follows:

2. Setting Variables within Blade Templates:

In addition to passing variables from controllers, Laravel also allows you to set variables directly within Blade templates. This feature can be useful when you need to perform calculations or modify data before displaying it.

To set a variable within a Blade template, you can use the @php directive. Here’s an example:

In this example, we set three variables: $name , $age , and $isStudent . These variables can be accessed and used within the template as needed.

3. Conditionally Setting Variables:

In some cases, you may need to conditionally set variables based on certain criteria. Laravel Blade provides various conditional directives to accomplish this.

For instance, you can use the @if directive to set a variable based on a condition:

In this example, the $accessLevel variable is conditionally set based on the value of the $isAdmin variable.

Conclusion:

Setting variables in Laravel Blade templates is a fundamental skill for building dynamic and interactive web applications.

In this blog post, we explored two methods of passing variables from controllers to views, as well as how to set variables directly within Blade templates using the @php directive.

We also touched on conditional variable setting using Blade’s conditional directives.

Laravel 10 continues to enhance the templating experience with new features and improvements. By mastering variable handling in Blade templates, you can create expressive and flexible views in your Laravel applications.

Remember, proper use of variables in Blade templates helps maintain clean, organized, and maintainable code. Happy coding with Laravel 10!

Declaring a variable in blade php (LARAVEL UPDATED)

Hi everyone, I'm fairly new to Laravel and I'm currently working on a blade template. I'm trying to declare a variable within the blade template itself, but I'm not sure of the correct syntax to use. I understand that in regular PHP, we would simply use the "$" sign followed by the variable name. However, I'm not sure if the same syntax applies within the blade template. Could someone please help me with the correct syntax to declare a variable within a blade template? Any guidance or examples would be greatly appreciated. Thanks in advance for your help!

Hey there, I understand your query as I also had a similar question when I first started using Laravel's blade templates. Declaring a variable within a blade template is straightforward. You can accomplish this by using the "@" symbol followed by the keyword "php" and enclosing your code within "@php" and "@endphp" tags. Here's an example: @php $message = "Hello, Laravel!"; @endphp Once you've declared the variable, you can utilize it within the blade template using the "{{$message}}" syntax. You can also perform operations or concatenate the variable with other strings, just like in regular PHP. Remember, the blade template engine transforms your code into regular PHP code during compilation, allowing you to use PHP syntax within the template. Feel free to ask if you have any further questions. Cheers!

Hey there, I can definitely help you with declaring a variable in a Laravel blade template. In Laravel's blade, you can declare a variable using the "@" symbol followed by the "php" keyword. Inside the "php" block, you can use the regular PHP syntax to declare your variables. For example, let's say you want to declare a variable called "name" and assign it the value "John". You can do it like this: @php $name = "John"; @endphp After declaring the variable, you can use it throughout your blade template by simply using "{{$name}}" to display its value or perform any other operations. I hope this helps! Let me know if you have any other questions or need further assistance. Cheers!

How to Set Variables in a Laravel Blade Template

I'm reading the Laravel Blade documentation and I can't figure out how to assign variables inside a template for use later. I can't do {{ $old_section = "whatever" }} because that will echo "whatever" and I don't want that.

I understand that I can do <?php $old_section = "whatever"; ?> , but that's not elegant.

Is there a better, elegant way to do that in a Blade template?

It is discouraged to do in a view so there is no blade tag for it. If you do want to do this in your blade view, you can either just open a php tag as you wrote it or register a new blade tag. Just an example:

I also struggled with this same issue. But I was able to manage this problem by using following code segment. Use this in your blade template.

I don't think that you can - but then again, this kind of logic should probably be handled in your controller and passed into the view already set.

I was looking for a way to assign a value to a key and use it many times in my view. For this case, you can use @section{"key", "value"} in the first place and then call @yield{"key"} to output the value in other places in your view or its child.

Hacking comments is not a very readable way to do it. Also editors will color it as a comment and someone may miss it when looking through the code.

Try something like this:

It will compile into:

...and do the assignment and not echo anything.

It's better to practice to define variable in Controller and then pass to view using compact() or ->with() method.

Otherwise #TLGreg gave best answer.

There is a very good extention for Blade radic/blade-extensions . After you add it you can use @set(variable_name, variable_value)

In my opinion it would be better to keep the logic in the controller and pass it to the view to use. This can be done one of two ways using the 'View::make' method. I am currently using Laravel 3 but I am pretty sure that it is the same way in Laravel 4.

The 'with' method is chainable. You would then use the above like so:

More information here:

http://three.laravel.com/docs/views

http://codehappy.daylerees.com/using-controllers

I had a similar question and found what I think to be the correct solution with View Composers

View Composers allow you to set variables every time a certain view is called, and they can be specific views, or entire view templates. Anyway, I know it's not a direct answer to the question (and 2 years too late) but it seems like a more graceful solution than setting variables within a view with blade.

laravel 5 you can easily do this . see below

You can extend blade by using the extend method as shown below..

after that initialize variables as follows.

inside the blade file, you can use this format

In laravel8

LARAVEL 5.5 AND UP

Use the full form of the blade directive:

LARAVEL 5.2 - 5.4

You can use the inline tags:

Or you can use it in a block statement:

ADD A 'DEFINE' TAG

If you want to use custom tags and use a @define instead of @php, extend Blade like this:

Then do one of the following:

Quick solution: If you are lazy, just put the code in the boot() function of the AppServiceProvider.php.

Nicer solution: Create an own service provider. See https://stackoverflow.com/a/28641054/2169147 on how to extend blade in Laravel 5. It's a bit more work this way, but a good exercise on how to use Providers :)

You can just put the above code on the bottom of app/start/global.php (or any other place if you feel that is better).

After the above changes, you can use:

to define a variable.

In laravel-4 , you can use the template comment syntax to define/set variables.

Comment syntax is {{-- anything here is comment --}} and it is rendered by blade engine as

<?php /* anything here is comment */ ?>

so with little trick we can use it to define variables, for example

will be rendered by blade as <?php /* */$i=0;/* */ ?> which sets the variable for us. Without changing any line of code.

There is a simple workaround that doesn't require you to change any code, and it works in Laravel 4 just as well.

You just use an assignment operator ( = ) in the expression passed to an @if statement, instead of (for instance) an operator such as == .

Then you can use it anywhere you can use any other variable

The only downside is your assignment will look like a mistake to someone not aware that you're doing this as a workaround.

Ya'll are making it too complicated.

Just use plain php

(or https://github.com/alexdover/blade-set looks pretty straighforward too)

We're all kinda "hacking" the system by setting variables in views, so why make the "hack" more complicated then it needs to be?

Tested in Laravel 4.

Another benefit is that syntax highlighting works properly (I was using comment hack before and it was awful to read)

Since Laravel 5.2.23, you have the @php Blade directive , which you can use inline or as block statement:

You Can Set Variables In The Blade Templating Engine The Following Ways: 1. General PHP Block Setting Variable: <?php $hello = "Hello World!"; ?> Output: {{$hello}} 2. Blade PHP Block Setting Variable: @php $hello = "Hello World!"; @endphp Output: {{$hello}}

You can set a variable in the view file, but it will be printed just as you set it. Anyway, there is a workaround. You can set the variable inside an unused section. Example:

Then {{ $yourVar }} will print Your value anywhere you want it to, but you don't get the output when you save the variable.

EDIT: naming the section is required otherwise an exception will be thrown.

In laravel document https://laravel.com/docs/5.8/blade#php You can do this way:

In Laravel 4:

If you wanted the variable accessible in all your views, not just your template, View::share is a great method ( more info on this blog ).

Just add the following in app/controllers/BaseController.php

and now $myvar will be available to all your views -- including your template.

I used this to set environment specific asset URLs for my images.

And suddenly nothing will appear. From my experience, if you have to do something like this prepare the html in a model's method or do some reorganizing of your code in to arrays or something.

There is never just 1 way.

I'm going to extend the answer given by @Pim.

Add this to the boot method of your AppServiceProvider

This way you don't expose the ability to write any php expression.

You can use this directive like:

Laravel 7 :

In Laravel 5.1, 5.2 :

https://laravel.com/docs/5.2/views#sharing-data-with-all-views

You may need to share a piece of data with all views that are rendered by your application. You may do so using the view factory's share method. Typically, you should place calls to share within a service provider's boot method. You are free to add them to the AppServiceProvider or generate a separate service provider to house them.

Edit file: /app/Providers/AppServiceProvider.php

You may use the package I have published: https://github.com/sineld/bladeset

Then you easily set your variable:

As for my elegant way is like the following

And just echo your $old_section variable.

If you have PHP 7.0:

The simple and most effective way is with assignment inside brackets .

The rule is simple: Do you use your variable more than once? Then declare it the first time it's used within brackets, keep calm and carry on.

And yes, I know about @forelse , this is just a demo.

Since your variables are now declared as and when they are used, there is no need for any blade workarounds.

Assign variable to the blade template, Here are the solutions

We can use <?php ?> tag in blade page

We can use the blade comment with special syntax

Laravel: How to Pass PHP Variables to JavaScript in Blade Templates

In modern web applications, it’s not uncommon to combine server-rendered templates with client-side interactivity powered by JavaScript. Laravel, a popular PHP framework, offers an elegant templating engine called Blade, which makes it easy to connect PHP back-end logic with front-end JavaScript. This tutorial covers several methods for passing PHP variables to JavaScript within Laravel’s Blade templates.

Understanding Blade

Before diving into passing variables, it’s important to have a basic understanding of Blade. Blade is the simple, yet powerful templating engine provided with Laravel, known for its elegant syntax and ability to inherit and extend layouts. Inside your Blade views – typically located in the resources/views directory – you write HTML mixed with Blade directives, which are processed on the server to produce the final HTML sent to the client.

Passing Variables: The Basics

Here’s the simplest way to pass a PHP variable to JavaScript:

This leverages Blade’s @json directive, which turns a PHP variable into its JSON equivalent, ensuring that it’s correctly formatted for JavaScript consumption. The produced output in the HTML would look something like this:

This method is appropriate for simple scenarios where you need to pass basic data types or array structures.

Using Blade’s Stack Directive

In cases where you wish to standardize how scripts are included across different views, you can utilize Blade’s @stack directive. Place a stack directive in your main layout file and then push to the stack from child views:

This method bundles all your script customizations in one place, making your templates neater and your JavaScript easier to manage.

Utilizing Controller Data

Another approach involves directly passing data from a controller to a view. When returning a view from your controller, you can include additional data:

In your Blade template, you can then access the $user object:

However, this method should be used prudently to avoid passing sensitive data to the client side unintentionally, as it is accessible through the source code of the webpage.

Using a Global JavaScript Object

For a more advanced approach, you can encapsulate all your PHP variables into a global JavaScript object. This can keep namespaced and organized:

This pattern is very useful when you need to make multiple PHP variables available globally in your JavaScript files. It avoids polluting the global namespace excessively and groups related data logically under the Window.Laravel object.

Complex Data Structures

Passing more complex data structures, such as collections or Eloquent models, requires careful handling. Relations and dates within these structures may need special attention and, potentially, serialization. A safe way to do this is to transform your structures to arrays or JSON prior to assigning them to JavaScript variables:

And in your Blade template:

The use of the {!! !!} directive prevents Blade from escaping the output, which is necessary here since toJson() produces a JSON string. Both @json and {{ }} would automatically escape the output leading to double encoding. Use this with caution to avoid XSS vulnerabilities, ensuring your data is clean before printing it unescaped.

Best Practices for Security

When passing PHP variables to JavaScript, always consider the security implications. Sanitize the data if necessary, use escaping functions to prevent XSS attacks, and never expose sensitive information. Laravel provides many tools for this (like e() for HTML entities encoding).

Frontend Build Tools

For larger applications, particularly those using front-end frameworks like Vue or React, you might compile your assets with tools like Laravel Mix, Webpack, or even use Laravel’s Vite integration. In such cases, you can pass data to your JavaScript app using global variables as shown earlier or adopt package specific strategies such as inline scripts or using dynamic imports with promises.

Passing data from PHP to JavaScript in Laravel Blade templates can be achieved through various methods, depending on your application’s structure and data complexity. While it’s a powerful feature, developers must handle it with care, particularly concerning the security of the data being passed. By following these practices, you can seamlessly integrate PHP and JavaScript while keeping your application organized and secure.

Variable variables

Sometimes it is convenient to be able to have variable variable names. That is, a variable name which can be set and used dynamically. A normal variable is set with a statement such as:

A variable variable takes the value of a variable and treats that as the name of a variable. In the above example, hello , can be used as the name of a variable by using two dollar signs. i.e.

At this point two variables have been defined and stored in the PHP symbol tree: $a with contents "hello" and $hello with contents "world". Therefore, this statement:

produces the exact same output as:

i.e. they both produce: hello world .

In order to use variable variables with arrays, you have to resolve an ambiguity problem. That is, if you write $$a[1] then the parser needs to know if you meant to use $a[1] as a variable, or if you wanted $$a as the variable and then the [1] index from that variable. The syntax for resolving this ambiguity is: ${$a[1]} for the first case and ${$a}[1] for the second.

Class properties may also be accessed using variable property names. The variable property name will be resolved within the scope from which the call is made. For instance, if you have an expression such as $foo->$bar , then the local scope will be examined for $bar and its value will be used as the name of the property of $foo . This is also true if $bar is an array access.

Curly braces may also be used, to clearly delimit the property name. They are most useful when accessing values within a property that contains an array, when the property name is made of multiple parts, or when the property name contains characters that are not otherwise valid (e.g. from json_decode() or SimpleXML ).

Boost Your Laravel Templates with Custom Blade Directives

driesvints, zamon, achmedislamic, massimoselvi liked this article

Introduction

Blade is a powerful templating engine that you can use in Laravel. It allows you to write clean templates using simple and understandable syntax to build some pretty complex layouts.

One of the cool features that I like about Blade is the ability to create your own custom directives. They allow you to define your own custom syntax that you can use in your Blade templates to make them more expressive and easier to read.

In this article, we'll take a look at how to create your own custom Blade directives in Laravel.

What are Blade Directives?

Blade directives are handy little shortcuts that you can add to your templates to reduce the need of using raw PHP. They start with the @ symbol, followed by the directive and any arguments.

If you've used Laravel before, you'll have likely interacted with Blade directives without realising. For example, you may have written an if statement in your Blade template using the @if and @endif directives like so:

When the Blade template is converted to regular PHP, it will be converted to this:

As you can see, although the raw PHP version isn't quite as elegant, it's still pretty easy to read.

So, to show the amount of complexity that Blade hides from us, let's take a look at another seemingly simple directive that has quite a lot going on behind the scenes.

You may have used the @foreach and @endforeach directives to loop through a collection of items:

When this Blade template is converted to regular PHP, it will be converted to this:

As you can see, there's a lot more going on here that Blade tidies away nicely for us.

Laravel comes with many built-in Blade directives, which you can check out in the documentation . For a large majority of your projects' needs, these directives will likely provide all the functionality you need.

But there may be times when you want to create your own custom Blade directives. You might want to do this if you find yourself writing the same small pieces of code over and over again. So it can be a nice way to simplify your templates and make them more expressive.

However, it's worth noting that if the code you keep rewriting is more than a few lines long, you might want to consider moving it into a component instead. Directives are best suited for short pieces of code (maybe one or two PHP statements).

Creating Custom Blade Directives

Let's take a quick look at how you can write your own custom Blade directives.

We'll imagine that we want to write a custom directive that renders a Carbon date object in a specific human-friendly format. We'll call this directive @friendlyDateTime .

Before we try creating the new directive, let's take a look at how we would write the code to render a Carbon date object in the format we want without using a custom directive. We might do something like this:

Running the above code would output the following:

Now let's convert this code to a Blade directive. To do this, we'll need to register the directive with the Blade compiler. We can do this by using the Blade::directive method in a service provider. For the purpose of this article, we're going to use the existing AppServiceProvider , but you may wish to add this code to a new service provider if you prefer.

Let's take a look at the code where we've registered the directive:

As we can see in the code above, we've defined a new @friendlyDateTime directive that accepts a string, such as $user->created_at . When the Blade templates are compiled into plain PHP code, it will look something like this:

In our Blade templates, we should be able to use the @friendlyDateTime directive. Here are a few examples of how you may want to use it:

As you can see, it's relatively simple to create your own custom Blade directives. You may also want to add more complex logic to these directives. For example, you may decide to add the ability for your application's users to choose the date format they see (which we'll assume is stored in a datetime_format field on the users table).

So, you could change your Blade directive code like so:

If we were to imagine that some users would prefer to see "Fri Mar 24 2023 @ 14:30" rather than "Fri 24 Mar 2023 @ 14:30", this directive would handle this without us needing to add any conditional logic to our templates.

Hopefully, this article should have given you a quick insight into what Blade directives are, how they work, and how to create your own.

If you enjoyed reading this post, I'd love to hear about it. Likewise, if you have any feedback to improve the future ones, I'd also love to hear that too.

PHP Tutorial

Php advanced, mysql database, php examples, php reference, php variables.

Variables are "containers" for storing information.

Creating (Declaring) PHP Variables

In PHP, a variable starts with the $ sign, followed by the name of the variable:

In the example above, the variable $x will hold the value 5 , and the variable $y will hold the value "John" .

Note: When you assign a text value to a variable, put quotes around the value.

Note: Unlike other programming languages, PHP has no command for declaring a variable. It is created the moment you first assign a value to it.

Think of variables as containers for storing data.

A variable can have a short name (like $x and $y ) or a more descriptive name ( $age , $carname , $total_volume ).

Rules for PHP variables:

  • A variable starts with the $ sign, followed by the name of the variable
  • A variable name must start with a letter or the underscore character
  • A variable name cannot start with a number
  • A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ )
  • Variable names are case-sensitive ( $age and $AGE are two different variables)

Remember that PHP variable names are case-sensitive!

Output Variables

The PHP echo statement is often used to output data to the screen.

The following example will show how to output text and a variable:

The following example will produce the same output as the example above:

The following example will output the sum of two variables:

Note: You will learn more about the echo statement and how to output data to the screen in the PHP Echo/Print chapter .

PHP is a Loosely Typed Language

In the example above, notice that we did not have to tell PHP which data type the variable is.

PHP automatically associates a data type to the variable, depending on its value. Since the data types are not set in a strict sense, you can do things like adding a string to an integer without causing an error.

In PHP 7, type declarations were added. This gives an option to specify the data type expected when declaring a function, and by enabling the strict requirement, it will throw a "Fatal Error" on a type mismatch.

You will learn more about strict and non-strict requirements, and data type declarations in the PHP Functions chapter.

Variable Types

PHP has no command for declaring a variable, and the data type depends on the value of the variable.

PHP supports the following data types:

  • Float (floating point numbers - also called double)

Get the Type

To get the data type of a variable, use the var_dump() function.

The var_dump() function returns the data type and the value:

See what var_dump() returns for other data types:

Assign String to a Variable

Assigning a string to a variable is done with the variable name followed by an equal sign and the string:

String variables can be declared either by using double or single quotes, but you should be aware of the differences. Learn more about the differences in the PHP Strings chapter .

Assign Multiple Values

You can assign the same value to multiple variables in one line:

All three variables get the value "Fruit":
