Here are the fresher level Laravel interview questions and their answers:

1. What is Laravel, and why is it popular?

Answer: Laravel is an open-source PHP web framework designed for web application development. It’s popular due to its elegant syntax, expressive code, and a wide range of built-in features that make development faster and easier.

2. What is Composer in Laravel?

Answer: Composer is a dependency management tool used in Laravel to manage and install PHP packages and libraries.

3. Explain the MVC architecture in Laravel.

Answer: MVC stands for Model-View-Controller. In Laravel, the model represents the data, the view displays the data, and the controller handles user requests and business logic.

4. How do you create a new Laravel project?

Answer: You can create a new Laravel project using the Composer command: composer create-project --prefer-dist laravel/laravel project-name.

5. What is Blade in Laravel?

Answer: Blade is Laravel’s templating engine, which allows you to write concise and expressive templates for your views.

6. Explain Eloquent ORM.

Answer: Eloquent is Laravel’s ORM (Object-Relational Mapping) system. It provides an expressive way to interact with databases, allowing you to work with database tables using object-oriented syntax.

7. How can you define a route in Laravel?

Answer: You can define a route in the routes/web.php or routes/api.php file using the Route facade. For example: Route::get('/path', 'Controller@method').

8. What is middleware in Laravel?

Answer: Middleware is a filter for HTTP requests. It allows you to perform actions before or after a request enters your application, such as authentication and logging.

As the name suggests, middleware works as a middleman between request and response. Laravel Middleware is a form of HTTP requests filtering mechanism. For example, Laravel consists of middleware which verifies whether the user of the application is authenticated or not. If a user is authenticated and trying to access the dashboard then, the middleware will redirect that user to home page; otherwise, a user will be redirected to the login page.

There are two types of middleware available in Laravel:

  • Global Middleware
    • It will run on every HTTP request of the application.
  • Route Middleware
    • It will be assigned to a specific route.


php artisan make:middlewareUserMiddleware  

Now, UserMiddleware.php file will be created in app/Http/Middleware.

9. What is a migration in Laravel?

Answer: Migrations are a way to version-control your database schema and apply changes to it over time. You can create and run migrations using Artisan commands.

A migration file includes two methods, up() and down(). A method up() is used to add new tables, columns or indexes database and the down() method is used to reverse the operations performed by the up() method.

You can generate a migration and its file by using the php artisan make:migration:

php artisan make:migration blog  

By using it, a current date blog.php file will be created in database/migrations.

10. Explain the concept of Dependency Injection in Laravel.

Answer: Dependency Injection is a design pattern in Laravel where dependencies are “injected” into a class rather than being created within the class. This promotes code reusability and testability.

11. How can you validate form data in Laravel?

Answer: Laravel provides a built-in validation system. You can define validation rules in a controller and use the validate() method to check incoming data.

Here is an example to validate form data using the validate method in the controller:

$this->validate($request, [
    'field' => 'required|other_rules',

12. What are service providers in Laravel?

Answer: Service providers are a way to bootstrap and register services with Laravel’s service container. They help manage dependencies and configure various components of the framework.

An artisan command is given here which can be used to generate a service provider:

php artisan make: provider ClientsServiceProvider  

Almost, all the service providers extend the Illuminate\Support\ServiceProviderclass. Most of the service providers contain below-listed functions in its file:

  • Register() Function
  • Boot() Function

Within the Register() method, one should only bind things into the service container. One should never attempt to register any event listeners, routes, or any other piece of functionality within the Register() method.

13. How can you create and run database seeders?

Answer: Database seeders are used to populate your database with sample data. You can create and run seeders using Artisan commands.

14. Explain the concept of Laravel Homestead.

Answer: Laravel Homestead is a Vagrant box that provides a development environment with everything you need to get started with Laravel.

15. What is method injection in Laravel?

Answer: Method injection allows you to type-hint dependencies in a controller method’s signature, and Laravel’s service container will automatically resolve and inject those dependencies.

It allows us to perform database operations, such as querying and updating data, and encapsulates the business logic related to that data.

29: What is the purpose of a migration in Laravel, and how do you create one using the artisan command?

Migrations in Laravel are used to manage the database schema and structure. They allow you to version-control your database schema changes, making it easy to share and replicate your database structure across different environments. To create a migration using the artisan command, you can run php artisan make:migration create_table_name.

30: Explain how you would add columns to a table within a migration file?

To add columns to a table within a migration file, you would open the generated migration file (in the database/migrations directory) and use the table method within the up method of the migration class. For example:

public function up()
    Schema::table('table_name', function (Blueprint $table) {

30. What is the difference between return, return view(), and return redirect() in a controller method?
