What is Laravel?

Laravel is a modern PHP framework that helps you build web applications quickly using the MVC architecture.

Example:
composer create-project laravel/laravel myApp

Example Description:

This creates a new Laravel project named myApp.
MVC Structure

MVC stands for Model-View-Controller — a design pattern that organizes code.

Example:
// routes/web.php Route::get('/hello', 'HelloController@index');

Example Description:

This defines a route /hello that is handled by the index method in HelloController.
Defining Routes

Routes define how your app responds to URLs.

Example:
Route::get('/about', function () { return 'About Page'; });

Example Description:

Displays a simple text response when visiting /about.
Creating a Controller

Controllers handle business logic and connect models to views.

Example:
php artisan make:controller BlogController

Example Description:

Creates a new controller named BlogController.
Blade Templates

Blade is Laravel's templating engine used to generate dynamic views.

Example:
<!-- resources/views/welcome.blade.php --> <h1>Hello, {{ $name }}</h1>

Example Description:

Displays a dynamic name in the header.
Database Migrations

Migrations help define and modify database schema in code.

Example:
php artisan make:migration create_posts_table

Example Description:

Generates a migration file to create a posts table.
Eloquent ORM

Eloquent allows you to interact with the database using models.

Example:
$post = Post::find(1); echo $post->title;

Example Description:

Fetches a post with ID 1 and displays its title.
Authentication

Laravel provides built-in authentication scaffolding.

Example:
php artisan ui bootstrap --auth

Example Description:

Generates login, register, and logout pages automatically.
Validation

Laravel simplifies input validation.

Example:
$request->validate([ 'title' => 'required|min:3' ]);

Example Description:

Validates that title is required and must be at least 3 characters long.
Database Seeding

Seeders allow inserting sample data into your database for testing.

Example:
php artisan make:seeder PostSeeder

Example Description:

Generates a seeder class to populate the posts table.
