Laravel has become one of the most popular PHP frameworks in recent years, favored for its elegant syntax, powerful features, and developer-friendly tools. Whether you’re a junior developer or an experienced Laravel artisan, preparing for a Laravel job interview means brushing up on core concepts, best practices, and the latest features.
In this guide, we’ll walk through 25 essential Laravel interview questions, perfect for candidates preparing for developer roles.
Laravel is an open-source PHP framework that follows the MVC (Model-View-Controller) architecture. It’s known for its elegant syntax, robust features, and a developer-friendly approach to building scalable web applications.
MVC stands for Model-View-Controller. It separates the application logic (Controller), data (Model), and user interface (View), making the application modular and easier to maintain.
Composer is a dependency manager for PHP. Laravel uses Composer to manage its package dependencies, including the Laravel framework itself and third-party libraries.
Artisan is Laravel’s command-line interface. It offers helpful commands for database migrations, model creation, route listing, and more.
Routing allows you to map URLs to specific controllers or closures. Routes are defined in the routes/web.php file for web interfaces and routes/api.php for APIs.
Middleware filters HTTP requests entering your application. It’s commonly used for authentication, CORS headers, and request logging.
Eloquent is Laravel’s built-in ORM (Object-Relational Mapper). It provides a simple and fluent interface for interacting with the database using models.
In the model, define:
public function posts() {
return $this->hasMany(Post::class);
}
This means one user has many posts.
Migrations are version-controlled steps to define and modify your database schema. They allow teams to collaborate on database structure changes safely.
php artisan make:migration create_users_table
Then run it using:
php artisan migrate
Seeders are used to populate the database with test or demo data using PHP classes.
The .env file contains environment-specific variables like database credentials, mail drivers, and API keys. Laravel uses this file to manage different environment configurations.
Blade is Laravel’s built-in templating engine. It allows you to use PHP code within HTML using a clean and intuitive syntax like @if, @foreach, and @include.
Laravel automatically protects against cross-site request forgery by including a CSRF token in every form. The token is verified for every POST, PUT, PATCH, or DELETE request.
Facades provide a static interface to Laravel’s services, such as Cache, Route, or DB, offering simple syntax while maintaining testability.
The service container is a powerful tool for managing class dependencies and performing dependency injection, enabling inversion of control.
Service providers are the central place to configure Laravel applications. They bootstrap services, bind classes to the service container, and more.
You can validate form data using:
$request->validate([
'email' => 'required|email',
'password' => 'required|min:6'
]);
Or via custom request classes created using php artisan make:request.
Sanctum provides a lightweight authentication system for single-page applications (SPAs), mobile apps, and token-based APIs.
Passport is a full OAuth2 server implementation for Laravel, ideal for robust API authentication using access tokens.
Queues allow you to defer time-consuming tasks, like sending emails, to be processed in the background, improving performance.
Laravel uses the App\Exceptions\Handler class for all exception handling and integrates with tools like Bugsnag, Sentry, or Laravel Telescope for tracking errors.
Laravel interviews typically focus on core features, best practices, and real-world problem-solving scenarios. By preparing these 25 Laravel interview questions and understanding the “why” behind each concept, you’ll be well-equipped for your next technical interview.
