Laravel Interview Questions and Answers (2025 Updated)
1. What is Laravel and Why is it Used? [Beginner]
Laravel is a popular PHP framework that makes web development faster and easier. It provides built-in tools for routing, authentication, caching, and database management. Developers use Laravel because of its clean syntax, scalability, and strong community support.
2. Difference Between Laravel and Core PHP [Basic]
Core PHP requires writing code from scratch, while Laravel provides a structured MVC framework with ready-to-use features. Laravel is more secure, maintainable, and time-saving compared to raw PHP development.
3. Explain Artisan Commands in Laravel [Important]
Artisan is Laravel’s command-line tool that helps automate tasks. Common commands include php artisan serve for running the server, php artisan migrate for database migration, and php artisan make:model for generating models.
4. What is Middleware in Laravel?
Middleware in Laravel acts as a filter for HTTP requests. It can handle tasks like authentication, logging, and CSRF protection before the request reaches the controller.
5. Service Container and Service Providers Explained
The Service Container manages class dependencies, while Service Providers are responsible for bootstrapping and registering services in Laravel applications.
6. Laravel Eloquent ORM vs Query Builder
Eloquent ORM is an object-oriented way to interact with the database using models, while Query Builder provides a more direct SQL-like approach. Eloquent is more readable, but Query Builder is faster for complex queries.
7. What is CSRF Protection in Laravel?
CSRF (Cross-Site Request Forgery) protection ensures that malicious requests cannot be submitted from external sources. Laravel automatically generates CSRF tokens for form submissions to prevent attacks.
8. Explain Laravel Queues and Jobs
Queues in Laravel allow background task processing, such as sending emails or processing payments. Jobs are units of work that can be pushed into queues and executed later to improve performance.
9. What are Events and Listeners in Laravel?
Events represent an action (e.g., user registration), while Listeners handle the response (e.g., sending a welcome email). This helps create a decoupled and clean application architecture.
10. Laravel 10 vs Laravel 11 Features [Latest]
Laravel 10 introduced native type declarations, improved process handling, and Pest testing. Laravel 11 focuses on performance improvements, simplified configuration, and faster package updates.
11. Laravel Authentication & Authorization (Sanctum/Passport)
Laravel provides built-in authentication with login, registration, and password reset. For API authentication, Sanctum is lightweight, while Passport provides OAuth2-based secure authentication.
12. What is Dependency Injection in Laravel?
Dependency Injection allows classes to receive objects they depend on instead of creating them manually. Laravel’s Service Container automatically handles this, making code cleaner and testable.
13. Laravel Caching Strategies (Redis, File, Database)
Laravel supports multiple caching drivers such as File, Database, and Redis. Redis is the most powerful caching option, improving performance for large applications.
14. REST API Development with Laravel [Advanced]
Laravel is widely used for building REST APIs. It provides route handling, authentication (Sanctum/Passport), JSON responses, and resource controllers, making API development seamless.
15. Composer & Autoloading in Laravel
Composer is Laravel’s dependency manager that helps install packages. Autoloading ensures that classes are automatically loaded without manual require statements.
