1 - What is Laravel?
Laravel is a popular open source PHP framework designed for building web applications following the MVC (Model View Controller) architectural pattern. It provides elegant syntax and robust tools for tasks such as routing, authentication, sessions, and caching.
2) What are Service Providers in Laravel?
Service Providers are the central place of application bootstrapping in Laravel. They are responsible for binding functionality into the service container and are used to register services, routes, and event listeners.
3) What is Eloquent ORM?
Eloquent ORM (Object Relational Mapping) is Laravel's built in database abstraction layer. It allows developers to interact with the database using PHP syntax rather than SQL, enabling a more expressive way of working with database records.
4) Explain routing in Laravel.
Routing in Laravel defines the relationships between URLs and the actions that should be executed when those URLs are accessed. Routes can be defined in the `web.php` or `api.php` files, and Laravel supports various HTTP methods such as GET, POST, PUT, DELETE.
5) What are Middleware in Laravel?
Middleware in Laravel acts as a layer between the HTTP request and the application, allowing you to filter requests entering your application. Common middleware functions include authentication, logging, and CORS handling.
6) How does Laravel handle authentication?
Laravel provides a built in authentication system that makes it easy to manage user authentication using sessions, including features like registration, login, password reset, and user roles.
7) What is Blade templating in Laravel?
Blade is Laravel's powerful templating engine that enables developers to create dynamic views efficiently. It provides convenient shortcuts for tasks like extending layouts, including partial views, and handling control structures.
8) How do you handle database migrations in Laravel?
Database migrations in Laravel allow developers to define and modify the database schema programmatically. Using Artisan commands, you can create, run, roll back, and manage migrations, ensuring version control over your database structure.
9) What is the purpose of .env file in Laravel?
The `.env` file in Laravel is used to store environment specific configuration variables. It helps in separating sensitive data like database credentials, API keys, and application settings from the source code, making it easier to manage different environments (development, production).
10) What is Dependency Injection in Laravel?
Dependency Injection is a design pattern used in Laravel that allows for injecting dependencies into classes rather than creating them inside the class. This enhances testability and promotes loose coupling between components.
11 - Can you explain what Laravel's Query Builder is?
Laravel's Query Builder provides a fluent interface to build SQL queries programmatically, enabling developers to interact with the database without needing to write raw SQL. It supports various database operations like SELECT, INSERT, UPDATE, and DELETE.
12) What are Laravel Facades?
Facades in Laravel provide a static interface to classes that are available in the application's service container. They simplify working with various components by allowing for easy access to services without needing to instantiate classes manually.
13) How do you manage sessions in Laravel?
Laravel manages sessions using a session service provider that stores session data in various ways (file, database, cookie, etc.). Developers can easily configure the session driver in the `.env` file and use built in functions to read and write session data.
14) Explain how validation works in Laravel.
Laravel provides a validation service that allows for validating incoming data before processing it. You can define validation rules in controller methods or form request classes, and Laravel will automatically redirect users back with error messages if validation fails.
15) What are Events and Listeners in Laravel?
Events and Listeners in Laravel allow you to implement a publish subscribe pattern within your application. Events are dispatched when specific actions occur, and listeners are responsible for handling those events, allowing for decoupled code and better separation of concerns.
Here are additional key concepts and features related to Laravel that can enhance your understanding of the framework:
16) What is Laravel’s Artisan CLI?
Artisan is Laravel's command line interface that provides a number of helpful commands for application management. Developers can use Artisan to perform tasks such as creating new controllers, running migrations, and generating boilerplate code quickly through artisan commands.
17) What is CSRF Protection in Laravel?
Cross Site Request Forgery (CSRF) protection in Laravel helps prevent unauthorized actions on behalf of a user who is authenticated. Laravel automatically generates a CSRF token for each active user session, which must be included in forms and AJAX requests to protect against CSRF attacks.
18) Explain Laravel’s Testing framework.
Laravel provides built in support for testing with PHPUnit, allowing developers to write unit tests and feature tests. The framework includes helpers and tools to facilitate testing, making it easier to ensure the application behaves as expected.
19) What is the Laravel File Storage system?
Laravel's File Storage system provides an abstraction layer for file storage using various file systems such as local, Amazon S3, and Cloud Storage. It simplifies file uploads and management by using a unified API to interact with different storage systems.
20) What are Resource Controllers in Laravel?
Resource controllers in Laravel provide a way to group common actions (index, create, store, show, edit, update, destroy) related to a resource under a single controller class. They follow RESTful conventions and simplify managing resources in a web application.
21 - How does Laravel handle localization?
Laravel provides a localization feature that allows developers to create applications in multiple languages. Using language files and the built in localization functions, you can easily manage and display messages in different languages based on user preferences.
22) What are Policies in Laravel?
Policies in Laravel are used to authorize user actions against specific models. They encapsulate authorization logic into dedicated classes, allowing you to define rules for user permissions based on attributes of the user and the resource being accessed.
23) Explain Laravel’s Security Features.
Laravel comes equipped with various security features, including SQL Injection prevention through prepared statements, XSS protection via HTML escaping, and built in mechanisms for encrypting sensitive data, enhancing application security.
24) What are Laravel Jobs and Queues?
Laravel Jobs and Queues allow for the deferred execution of time consuming tasks such as sending emails or processing uploads. By queuing these jobs, you can enhance application performance and user experience, enabling asynchronous operations.
