Laravel is a free, open-source PHP web framework used for web application development. It is a popular choice for developers because of its elegant syntax, which makes it easy to read and write. Laravel also comes with a range of features that make it easier to build modern, robust, and scalable web applications, such as routing, authentication, and a templating engine.
A Laravel developer is a software developer who specializes in the Laravel web application framework. They use Laravel to build and maintain web applications, typically working with PHP and MySQL. Laravel developers are responsible for the development and maintenance of web applications, from the initial stages of planning and design to testing and deployment. They may also be involved in the ongoing maintenance and updates of the application.
To become a Laravel developer, you will typically need to have strong skills in PHP, as well as experience with object-oriented programming and web development concepts. It is also helpful to have experience with other related technologies, such as HTML, CSS, and JavaScript. You can learn Laravel through online tutorials and courses, or by building your own projects and working on open-source projects.
In this Blog, we are going to see 60+ Laravel interview questions and answers with examples.
Answer: Laravel is a free, open-source PHP web framework used for web application development. It is known for its elegant syntax and tools for tasks such as routing, authentication, and caching.
Answer: Some key features of Laravel include a modular packaging system with a dedicated dependency manager, different ways to access relational databases, utilities for application deployment and maintenance, and its orientation toward syntactic sugar.
Answer: Laravel distinguishes itself from other PHP frameworks by emphasizing simplicity, clarity, and getting work done. It aims to make tasks that are common in web development, such as routing and authentication, easier to complete.
Answer: A route is a URL pattern that is used to handle HTTP requests. In Laravel, routes are defined in the app/Http/routes.php file. They are used to map a request to a specific controller action.
Answer: A controller is a PHP class that handles HTTP requests. It is used to manage the logic for a particular part of the application. In Laravel, controllers are stored in the app/Http/Controllers directory.
Answer: To create a migration, use the Artisan command-line interface included with Laravel. Run the following command:
PHP artisan make: migration create_users_tableThis will create a new migration file in the database/migrations directory.
Answer: Eloquent ORM (Object-Relational Mapping) is a PHP library that simplifies the process of working with relational databases. In Laravel, Eloquent ORM is used to define relationships between models and interact with the database.
Answer: A middleware is a layer of software that sits between the application and the HTTP server. In Laravel, middleware provides a convenient mechanism for filtering HTTP requests and taking actions based on the request.
Answer: To create a custom middleware, use the Artisan command-line interface included with Laravel. Run the following command:
php artisan make:middleware CheckAgeThis will create a new middleware class in the app/Http/Middleware directory.
Answer: A request is an HTTP request made to a server. In Laravel, requests are represented as objects and can be accessed via the Request facade or injected into a controller method.
Answer: To create a custom request in Laravel, use the Artisan command-line interface included with Laravel. Run the following command:
php artisan make:request StoreBlogPostThis will create a new request class in the app/Http/Requests directory.
Answer: To create a blade template in Laravel, create a new file with a .blade.php extension in the resources/views directory. You can then use blade syntax in the template file to include PHP code and extend the layout.
Answer: A model in Laravel represents a table in a database and is used to interact with that table. Models allow you to query the database, insert new records, and update or delete existing records.
Answer: To create a model in Laravel, use the Artisan command-line interface included with Laravel. Run the following command:
php artisan make:model PostThis will create a new model class in the app directory.
Answer: To create a relationship between models in Laravel, use the appropriate relationship method in the model class. For example, to define a one-to-many relationship, you would use the hasMany method in the parent model and the belongsTo method in the child model.
Answer: Dependency injection is a technique for achieving loose coupling between objects and their dependencies. In Laravel, dependency injection is used to resolve class dependencies automatically by injecting them into the constructor or method.
Answer: A service provider is a central place to register your application's service containers and configurations. In Laravel, service providers are the central place to configure and bootstrap your application.
Answer: To create a service provider in Laravel, use the Artisan command-line interface included with Laravel. Run the following command:
php artisan make:provider AppServiceProviderThis will create a new service provider class in the app/Providers directory.
Answer: Artisan is the command-line interface for Laravel. It provides a number of helpful commands for your use while developing your application. To use an Artisan command, open the terminal and navigate to the root directory of your Laravel application. Then, enter the artisan command followed by the desired command and any necessary options.
For example:
php artisan make:migration create_users_tableAnswer: Laravel handles routing through the use of HTTP routes. These routes are defined in the app/Http/routes.php file. You can specify the HTTP method and URI that the route should respond to, and specify a closure or controller action that should be executed when the route is matched.
Example:
Route::get('/', function () {
return 'Hello World';
});Answer: When a request is made to a Laravel application, it is handled by the app/Http/Kernel.php file's HTTP kernel. The HTTP kernel contains a list of middleware that will be executed in the order they are listed. After the middleware has been executed, the request is then handed off to a route or controller.
Answer: Dependency injection is a technique where an object receives its dependencies from external sources rather than creating them itself. In Laravel, dependency injection is used to resolve class dependencies automatically by the service container.
Example:
class UserController extends Controller
{
public function show(Request $request, UserRepository $repository)
{
$user = $repository->find($request->id);
return view('user.show', ['user' => $user]);
}
}Answer: In Laravel, controllers are classes that are used to handle HTTP requests. They are defined in the app/Http/Controllers directory. You can define a controller by extending the base Controller class or by using a simple closure.
Example:
class UserController extends Controller
{
public function show($id)
{
$user = User::find($id);
return view('user.show', ['user' => $user]);
}
}Answer: Laravel's event system allows you to subscribe and listen to various events that occur in your application. You can use the Event facade or the event() helper function to trigger an event. You can also specify listeners for these events, which are classes or closures that will be executed when the event is fired.
Example:
Copy code
Event::listen('user.login', function ($user) {
// code to execute when the user.login event is fired
});
event(new UserLogin($user));Answer: Laravel provides support for executing tasks asynchronously using queues. Jobs are classes that represent a single task that should be executed and pushed onto a queue. Workers then process the jobs in the queue. This allows you to run time-consuming tasks in the background, improving the performance of your application.
Example:
class SendWelcomeEmail implements ShouldQueue
{
public function handle(User $user)
{
Mail::to($user->email)->send(new WelcomeEmail);
}
}
SendWelcomeEmail::dispatch($user);Answer: Laravel's Eloquent ORM provides support for defining relationships between models. There are several types of relationships available: one-to-one, one-to-many, many-to-many, and polymorphic relationships. You can define a relationship by adding a function to your model class and then calling the function to retrieve the related models.
Example:
class User extends Model
{
public function posts()
{
return $this->hasMany(Post::class);
}
}
$user = User::find(1);
$posts = $user->posts;Answer: Laravel provides several ways to validate incoming HTTP request data. You can use the built-in Validator class, or create custom validation rules. Validation rules can be specified in the form of an array or a rule string delimited by pipes.
Example:
$request->validate([
'title' => 'required|unique:posts|max:255',
'body' => 'required',
]);Answer: Laravel provides several ways to send HTTP requests. You can use the HTTP client provided by Guzzle, the HTTP facade, or the request() helper function.
Example:
$response = Http::get('https://example.com');
$response = request()->get('https://example.com');Answer: Laravel provides support for multiple cache backends, including file systems, databases, and memory. You can use the Cache facade or the cache() helper function to access the cache.
Example:
Cache::put('key', 'value', 10);
$value = cache('key');Answer: Laravel's task scheduler allows you to define scheduled tasks that will be automatically executed by the framework. You can use the Artisan CLI to schedule tasks or specify them in the app/Console/Kernel.php file.
Example:
$schedule->command('emails:send')->daily();Answer: Laravel provides support for storing and retrieving files through the use of the Storage facade or the storage() helper function. You can specify the disk you want to use for storage, which can be a local disk, a cloud storage provider, or a custom driver.
Example:
Storage::put('file.txt', 'content');
$contents = Storage::get('file.txt');Answer: Laravel's event broadcasting system allows you to broadcast events over a WebSocket connection. You can use Laravel Echo, a JavaScript library, to listen for events in the front end of your application.
Example:
Event::listen('event.name', function ($data) {
broadcast(new EventNameEvent($data));

php artisan make:middleware CustomMiddlewareThis will create a new file in the app/Http/Middleware directory. You can then define your custom middleware logic in this file.
Answer: You can define a custom validation rule by creating a new rule object and adding it to the $rules array in the Request object for the form you want to validate.
For example:
use Illuminate\Validation\Rule;
public function rules()
{
return [
'email' => [
'required',
Rule::unique('users')->ignore($this->route('user')),
],
];
}Answer: Laravel Envoy is a task runner for Laravel. To use Envoy, you can create an Envoy.blade.php file at the root of your project and define your tasks in this file.

public function phone()
{
return $this->hasOne(Phone::class);
}
}Answer: To perform database transactions in Laravel, you can use the DB facade's transaction method.
For example:
DB::transaction(function () {
// database statements go here
});Answer: To enable route caching in Laravel, you can use the route:cache Artisan command. This will create a compiled version of your routes file, which can improve the performance of your application.
Answer: To enable model caching in Laravel, you can use the Cache facade and the remember method on your model's query builder.
For example:
$users = Cache::remember('users', $minutes, function () {
return User::all();
});Answer: To clear the cache in Laravel, you can use the cache:clear Artisan command. This will clear all the caches for your application.
Answer: View composers allow you to share data with views across multiple routes. You can define a view composer by binding a closure to a view in the boot method of your AppServiceProvider.
For example:
View::composer('view-name', function ($view) {
$view->with('key', 'value');
});Answer: Route model binding allows you to automatically inject a model instance into your route. You can enable route model binding by specifying a {model} parameter in your route and defining a bind method in your route service provider.
For example:
Route::get('users/{user}', function (App\User $user) {
//
});Answer: You can use events in Laravel to execute code when certain actions occur in your application. To create an event, you can use the make:event Artisan command. You can then subscribe to the event using the listen method in your EventServiceProvider.
For example:
Event::listen('event-name', function ($data) {
// code to execute when the event occurs
});Answer: Policies in Laravel allow you to manage user authorization for your application. To create a policy, you can use the make:policy Artisan command. You can then define methods for each action you want to authorize.
For example:

return $user->id === $model->id;
}
}Answer: Jobs in Laravel allow you to execute time-consuming tasks asynchronously. To create a job, you can use the make:job Artisan command. You can then dispatch the job using the dispatch method.
For example:
$job = (new SendWelcomeEmail($user))
->onConnection('redis')
->onQueue('emails');
dispatch($job);Answer: Task scheduling in Laravel allows you to schedule repetitive tasks to run automatically at specified intervals. You can define your scheduled tasks in the schedule method of the App\Console\Kernel class.
For example:
