How to use Laravel6 framework in php?

PHP is a widely used server-side scripting language that can create dynamic web pages. Laravel is one of the PHP frameworks that helps developers build web applications and web services faster. It uses simple, elegant syntax, takes full advantage of PHP's latest features, and advanced ready-made PHP packages. This article will introduce you how to use the Laravel6 framework.

1. Installing Laravel6
   Before you start using Laravel6, you need to install PHP and Composer on your computer. Composer is a PHP dependency manager that helps you download and install PHP packages easily. Installing Laravel6 using Composer is very easy. Follow these steps:

1. Install PHP and Composer on your computer (if not already installed). You can download and install Composer from the official website (https://getcomposer.org/).

2. Open the terminal, go to the directory where you want to create the project, and run the following command:

composer create-project --prefer-dist laravel/laravel blog "6.*"

This command will download the latest version of Laravel6 on your computer and install it on your Create a new project in a directory named "blog".

3. Run the following command to start the local server:

php artisan serve

This will start a local development server and input its view files into the "http://localhost:8000" URL.

2. Creating Laravel6 Application Routes
   Routing is the way to specify the URL to access a web application. Laravel6 provides a convenient and easy-to-use routing system. You can open the "routes/web.php" file and see the following route definition:

   Route::get('/', function () {

    return view('welcome');

   });

This route handles the root URL from the web application. When the user accesses the root URL, Laravel6 will call an anonymous function and return the "welcome" view.

You can define additional URLs by adding routes. For example, if you want to create a route to handle the "about" page, you can add the following code to your routes file:

Route::get('/about', function () {
    return view('about');
});

This way when the user visits "http://localhost:8000/about" ", Laravel6 will call another anonymous function and return the "about" view.

3. Create Laravel6 Application Controller
   The controller is one of the core components of the Laravel6 application and is used to handle requests from users. You can create a new controller using the following command:

   php artisan make:controller UserController

This will be added in your Laravel6 application's "app/Http/ Create a new UserController class in the Controllers directory.

In this class, you can add multiple methods to handle different types of requests. For example, to handle login requests from users, you can add the following method:

public function login()
{
    // 处理登录请求
}

Then, you can create a route to associate this method with a specific URL:

Route::post('/login', 'UserController@login');

This The login() method in the UserController class will be called when the user submits the login form.

4. Create Laravel6 application tables
   Laravel6 comes with a database migration system, which has convenient methods to create, change and delete database tables. You can create a new migration using the following command:

   php artisan make:migration create_users_table

This will be in the "database/migrations" directory of your Laravel6 application Create a new "create_users_table" class in . You can use this class to define the schema of the table to be created. For example:

Schema::create('users', function (Blueprint $table) {
    $table->bigIncrements('id');
    $table->string('name');
    $table->string('email')->unique();
    $table->timestamp('email_verified_at')->nullable();
    $table->string('password');
    $table->rememberToken();
    $table->timestamps();
});

When you run migrations, Laravel6 will create a table named "users" based on this code.

5. Create Laravel6 Application Model
   Model is another one of the core components of Laravel6 application and is used to map database tables to PHP objects. You can create a new model using the following command:

   php artisan make:model User

This will be created in the "app" directory of your Laravel6 application A new User class. You can use this class to define a table to be accessed like an object. For example:

class User extends Model
{
    protected $fillable = [
        'name', 'email', 'password',
    ];
}

When you define modeled tables, you can use them just like regular PHP objects.
