The Laravel framework is an open source PHP framework that improves development efficiency through many modern features and convenient syntax. It adopts the MVC (Model-View-Controller) architecture design pattern, can easily create RESTful APIs and Web applications, and has excellent database processing capabilities.

This article will introduce the basic knowledge and steps of using the Laravel framework to help novices quickly master the use of the Laravel framework.

  1. Installing Laravel

First, download the latest stable version of the Laravel framework from the Laravel official website and unzip it. In addition, you will also need to install PHP and Composer. These tools will help you run and manage Laravel projects on your local computer.

  1. Create Laravel Project

Next, run the following command in the terminal to create a new Laravel project:

composer create-project --prefer-dist laravel/laravel your-project-name-here
  1. Run the Laravel project

When the project is created, you can use the following command to start Laravel's built-in development server:

php artisan serve

In this way, you can run Laravel in your local computer project, and visit http://localhost:8000 through the browser to view the project's welcome page.

  1. Learn the basic structure and syntax of Laravel

The Laravel framework adopts the MVC (Model-View-Controller) design pattern, so you need to first understand the basics of the MVC pattern knowledge, and then learn how to use Laravel's models, views, and controllers.

In Laravel, controllers are used to handle HTTP requests and responses, models are used to handle business logic that interacts with the database, and views are used to render HTML pages and other data interactions.

  1. Using Laravel's routing

The Laravel framework provides a very convenient routing system for handling HTTP requests and responses. You can create a new route file in the terminal using the following command:

php artisan make:controller YourControllerName

In the route file, you can define the HTTP verb and URI, as well as the function in the controller to be called when the route is executed:

Route::get('/path', 'YourControllerName@index');
Route::post('/path', 'YourControllerName@store');
  1. Views using Laravel

The Laravel framework provides a very flexible and easy-to-use Blade template engine, which allows you to create HTML views and layouts using simple syntax.

Use the following code in the controller to render the view:

public function index()
{
    return view('your-view-name');
}

Use the following syntax to render the data in the view:

{{ $variable }}
  1. Use Laravel’s database processing capabilities

The Laravel framework has excellent database processing capabilities, and you can use Eloquent ORM to process the database quickly and conveniently.

Use the following code in the controller to query the database and render the data:

public function index()
{
    $data = YourModel::all();
    return view('your-view-name', compact('data'));
}

Use the following syntax in the view to render the data:

@foreach($data as $item)
    {{ $item->column }}
@endforeach
  1. Use Laravel's middleware and validators

The Laravel framework provides the functionality of middleware and validators to help you filter and validate web requests.

Use the following code in the controller to use the middleware:

public function __construct()
{
    $this->middleware('auth');
}

Use the following code in the controller to verify the request:

public function store(Request $request)
{
    $validatedData = $request->validate([
        'name' => 'required|max:255',
        'email' => 'required|email|unique:users',
        'password' => 'required|confirmed',
    ]);
}
  1. Using Laravel’s Error Handling

The Laravel framework provides a professional error handling mechanism to help you capture and handle exceptions in web applications.

Use the following code in the controller to trigger the exception:

abort(404, 'Page not found!');

Use the following syntax in the view to render the error:

@if ($errors->any())
    <div class="alert alert-danger">
        <ul>
            @foreach ($errors->all() as $error)
                <li>{{ $error }}</li>
            @endforeach
        </ul>
    </div>
@endif
