1 - What is Laravel?
Laravel is a PHP framework that follows the Model View Controller (MVC) architectural pattern and is used to develop web applications.
2) Describe the MVC architecture in Laravel.
MVC separates the application into three main components: the Model (data), the View (presentation), and the Controller (logic).
3) What are Eloquent ORM and its benefits?
Eloquent is an Object Relational Mapping (ORM) that provides an elegant way to interact with databases. It allows you to define models that represent database tables and easily perform CRUD (Create, Read, Update, Delete) operations.
4) Explain routing in Laravel.
Routing is a mechanism that maps URLs to specific actions in your application. In Laravel, you can define routes using the “Route::…” facade in the “routes/web.php” file.
5) What is the Artisan CLI tool in Laravel?
Artisan is a powerful command line interface (CLI) tool that allows you to perform a variety of development tasks, such as generating code, running migrations, and interacting with the database.
6) Explain the concept of migrations in Laravel.
Migrations are a way to manage changes to your database schema. Laravel provides a fluent API to create and modify migrations, ensuring that the database structure is always in sync with the application's code.
7) What is the Service Container in Laravel?
The Service Container is a component that allows you to register and retrieve various services (e.g., database connections, HTTP clients) throughout your application.
8) Describe the role of Blade templating engine.
Blade is a template engine that helps you create dynamic and reusable views. It allows you to easily insert PHP code, control flow constructs, and access data from the controller.
9) How does error handling work in Laravel?
Laravel uses middleware, exceptions, and the “App\Exceptions\Handler” class to handle exceptions and errors gracefully and provide detailed error messages.
10) What security features are provided by Laravel?
Laravel includes built in security features, such as CSRF token verification, SQL injection protection, and HTTP headers to prevent vulnerabilities like XSS and clickjacking.
11 - How do you test Laravel applications?
Laravel provides support for unit, feature, and integration testing through its test suite. You can use the “php artisan test” command to run tests and assert the expected behavior.
12) Explain the use of Facades in Laravel.
Facades are static classes that provide a simple way to access various services and functionality from anywhere in your application, without having to worry about class instantiation or dependency injection.
13) Describe the purpose and advantages of Middleware.
Middleware is a mechanism that allows you to intercept and modify requests and responses before they reach the intended destination. It is a powerful tool for implementing security checks, logging, caching, and other cross cutting concerns.
14) How do you set up a queue in Laravel?
Laravel supports a variety of queuing systems, such as Redis, Beanstalkd, and Amazon SQS. You can configure and manage queues using the “queue” configuration file and console commands.
15) Explain the benefits and use cases of Event Listeners in Laravel.
Event Listeners allow you to listen for and respond to specific events that occur in your application, such as user registration or a model being updated. They provide a decoupled way to implement business logic and can be used for tasks like sending notifications and logging events.
