Key Features

• Routing: Laravel provides a robust routing system that allows for flexible and expressive route definitions.
• Eloquent ORM: Laravel's Eloquent ORM (Object-Relational Mapping) system provides a simple and intuitive way to interact with databases.
• Blade Templating: Laravel's Blade templating engine provides a simple and concise way to write templates.
• Request and Response: Laravel provides a simple and intuitive way to handle HTTP requests and responses.
• Middleware: Laravel's middleware system allows for the execution of code before or after a route is called.
• Security: Laravel provides built-in security features, such as CSRF protection and password hashing.

Laravel Architecture

• Application: The application folder contains the core application logic.
• App: The app folder contains the application's namespace.
• Config: The config folder contains configuration files.
• Database: The database folder contains database migrations and seeds.

Laravel Request and Response

• Request: The request object contains information about the incoming request.
• Response: The response object contains information about the outgoing response.
• Request Lifecycle: The request lifecycle includes the following stages: request creation, routing, middleware execution, and response creation.

Laravel Middleware

• Types of Middleware: There are two types of middleware: global middleware and route middleware.
• Middleware Execution: Middleware is executed in the order it is listed in the kernel.
• Stopping Middleware Execution: Middleware execution can be stopped by calling the terminate method.

Laravel Security

• CSRF Protection: Laravel provides built-in CSRF protection.
• Password Hashing: Laravel provides built-in password hashing using the Bcrypt algorithm.
• Encryption: Laravel provides built-in encryption using the OpenSSL library.
