1 - What is Laravel?
Laravel is a PHP framework designed for building web applications with an emphasis on clean and elegant syntax. It simplifies common tasks such as routing, authentication, and caching, allowing developers to focus on their application's business logic.
2) What are the key features of Laravel?
Key features of Laravel include Eloquent ORM for database interactions, a powerful routing system, middleware support, Blade templating engine, built in authentication and authorization, and support for unit testing.
3) Explain Eloquent ORM.
Eloquent ORM is Laravel's built in Object Relational Mapping system that provides a simple ActiveRecord implementation for working with database records. It allows developers to interact with the database using PHP syntax rather than raw SQL queries.
4) What is a service provider in Laravel?
Service providers are the central place of application bootstrapping in Laravel. They are responsible for binding services into the service container and are called on every request to register any application services.
5) How does Laravel manage database migrations?
Laravel manages database migrations using a version control system for your database schema. Developers can create migration files that define changes to the database structure, and these migrations can be executed through Artisan commands.
6) What is middleware in Laravel?
Middleware in Laravel is a way to filter HTTP requests entering the application. It can perform tasks like authentication, logging, or modifying requests before they reach the application's controllers.
7) Explain the purpose of routes in Laravel.
Routes in Laravel are used to define the URLs that the application responds to. They map to specific actions in controllers, allowing developers to manage the application's flow of requests effortlessly.
8) How can you protect against SQL injection in Laravel?
Laravel protects against SQL injection by using prepared statements and parameter binding with Eloquent ORM, ensuring that user inputs are properly escaped and secure.
9) What is the Blade templating engine?
Blade is Laravel's powerful templating engine that facilitates the creation of dynamic views. It allows developers to use PHP code in their views seamlessly and provides features like template inheritance and sections.
10) Explain dependency injection in Laravel.
Dependency injection in Laravel is a design pattern that allows the framework to manage class dependencies, improving code testability and reusability. Services can be automatically injected into controllers, routes, or any other components.
11 - What are Laravel facades?
Facades in Laravel provide a static interface to classes in the service container, making it easier to access underlying functionality without needing to resolve the classes manually.
12) How can you implement authentication in Laravel?
Laravel provides built in authentication features that can be easily configured using the `php artisan make:auth` command. This sets up necessary views and routes for user registration and login processes.
13) What is CSRF protection in Laravel?
Cross Site Request Forgery (CSRF) protection in Laravel is implemented by adding a CSRF token to forms, preventing unauthorized actions from being performed without the user's consent.
14) Explain the purpose of the `.env` file in Laravel.
The `.env` file is used to store environment specific configuration settings, such as database credentials and application keys, allowing developers to separate configuration from code and maintain different settings for development and production environments.
15) How do you handle validation in Laravel?
Laravel handles validation using the built in validation methods either through Form Requests or directly in controllers. Developers can define rules for input validation easily, ensuring data integrity before processing it.
16) What is Laravel Mix?
Laravel Mix is a build tool for compiling and optimizing frontend assets such as CSS and JavaScript. It offers a fluent API for defining webpack build steps for your application, making it easy to manage assets.
17) Describe the task scheduling feature in Laravel.
Laravel's task scheduling allows developers to define scheduled tasks directly in the application using a fluent, expressive syntax. This feature leverages Cron to run tasks at specific intervals, simplifying repetitive task management.
18) What are Laravel policies?
Policies in Laravel are a way to organize authorization logic around a particular model or resource. They define methods that determine whether a user can perform specific actions on that model, providing a clean approach to access control.
19) How does Laravel implement event broadcasting?
Laravel implements event broadcasting by allowing developers to create events and listeners that can be triggered and handled asynchronously. This enables real time functionalities through technologies like WebSockets, making it easier to build interactive applications.
20) What is the significance of the `php artisan` command?
The `php artisan` command is the command line interface included with Laravel, providing a variety of helpful commands for app development, such as creating migrations, controllers, models, and various tasks that automate project management.
21 - What are relationships in Eloquent ORM?
Relationships in Eloquent ORM define how different models are related to each other in the database. Laravel supports various relationship types, including one to one, one to many, many to many, and polymorphic relations, facilitating easier data retrieval and navigation.
22) Explain the concept of middleware groups.
Middleware groups in Laravel allow developers to group multiple middleware into a single alias. This feature enhances organization and simplifies route definitions by applying a set of middleware to specific routes or route groups.
23) What are job queues in Laravel?
Job queues in Laravel provide a way to delay the execution of tasks, moving them to a separate queue system. This feature is vital for improving application performance, especially while processing time consuming operations like sending emails or processing uploads.
24) How do you implement localization in Laravel?
Localization in Laravel is implemented using language files that store translations for your application. These files can be accessed easily across the app, allowing developers to create applications that support multiple languages.
25) What is the purpose of the `config` directory in Laravel?
The `config` directory in Laravel houses configuration files that define application settings and behavior. Each file corresponds to various application components, allowing developers to customize the framework's functionality to fit their needs.
26) How can you create and manage seeds in Laravel?
Seeding in Laravel allows developers to populate the database with test data using seeder classes. These classes can be executed through Artisan commands to establish initial data for development and testing purposes.
27) What is Tinker in Laravel?
Tinker is an interactive console that comes with Laravel, allowing developers to interact with their application’s database directly through a command line interface. This tool is beneficial for testing and experimenting with models and their methods.
28) Describe the concept of dependency management in Laravel.
Laravel utilizes the Composer dependency manager to manage package dependencies. Through Composer, developers can conveniently install, update, and manage external libraries required for their applications.
29) What is the role of the `public` directory in a Laravel application?
The `public` directory serves as the entry point for incoming web requests in a Laravel application. It contains assets like CSS, JavaScript, and images, as well as the `index.php` file that bootstraps the application.
30) Explain how session management works in Laravel.
Session management in Laravel is managed through a variety of session drivers, including files, cookies, databases, and cache. Laravel provides an easy way to store user session data and retrieve it across requests, enhancing user experience and state management.
