Introduction to Laravel

Laravel is a modern PHP web framework that follows the MVC pattern, offering expressive syntax, built-in tools for routing, authentication, and caching, and a thriving ecosystem with packages and extensions to accelerate web application development.

  • Configure environment in .env (DB, app key, cache).
  • Run local server: php artisan serve.
Laravel MVC Architecture

Blade Templating

  • Use .blade.php files for views.
  • Leverage directives like @yield, @section, @include.

Eloquent ORM
