How to use laravel

Laravel is a popular PHP web application framework that provides many useful features to help web developers quickly build and deploy high-quality web applications. Here are some basic steps to use Laravel:

1. Installing Laravel

First, you need to install Laravel on your local machine. You can use Composer to install Laravel on Windows, Mac, or Linux. Composer is a PHP dependency manager that automatically downloads and installs Laravel and its dependencies.

It’s very easy to install Laravel using Composer. Simply open a terminal or command prompt and enter the following command:

composer global require laravel/installer

This command will install the Laravel installer globally. Once the installation is complete, you can create a new instance of your Laravel project using the following command:

laravel new myproject

2. Configure Database

Laravel also requires a database to run. By default, Laravel uses the MySQL database, but it also supports other databases such as PostgreSQL, SQLite, and SQL Server. You need to configure the database connection information in the .env file. For example, if you are using a MySQL database, the .env file would look like this:

DB_DATABASE=your_database_name
DB_USERNAME=your_database_username
DB_PASSWORD=your_database_password

Be sure to replace these values ​​with your actual database name, username, and password.

3. Using Artisan Command Line Interface

Laravel comes with a command line interface tool called Artisan, which can help you perform various useful tasks such as code generation, Database migration, console commands and testing. The following are some commonly used Artisan commands:

• Generate controller: php artisan make:controller MyController
• Generate model: php artisan make:model MyModel
• Generate migration:php artisan make:migration create_users_table
• Run migration:php artisan migrate
• Generate seeder: php artisan make:seeder UserSeeder
• Run seeder:php artisan db:seed

4. Define route

Laravel uses routing to determine how to respond to requests from web browsers. In Laravel, routing is used to map URLs and request types to specific controller methods. To define a route, you open the routes/web.php file and add code similar to the following:

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

This code represents mapping the root URL to a view named welcome. You can also use other request types such as POST, PUT, PATCH, and DELETE. For example, the following code maps a POST request to the store method of a controller named UserController:

Route::post('/users', 'UserController@store');

5. Creating a Controller

The controller is used to handle requests for web applications , execute business logic and generate responses. You can create a controller using the Artisan command-line tools. For example, the following command will generate a controller named UserController:

php artisan make:controller UserController

This command will generate the UserController.php file in the app/Http/Controllers directory.

6. Creating Views

Views are the components in a Laravel application that handle the final HTML output. In Laravel, views are created using the Blade template engine. Views can contain static HTML, PHP code, and Laravel template syntax. You can create a new view using the following Artisan command:

php artisan make:view myview

This command will create a new file named myview.blade.php in the resources/views directory. You can add HTML, PHP code, and template tags (such as {{ $variable }} and @foreach) to generate views.

7. Run Laravel Application

When you are ready to run your Laravel application, you can enter the following command in the terminal or command prompt:

php artisan serve

This command will start the PHP built-in web server on localhost and run your Laravel application on http://localhost:8000.

Summary

Laravel is a simple and easy-to-use PHP web application framework that provides many useful features such as routing, controllers, views, and Artisan command line interface. By using Laravel, you can greatly speed up and simplify the development and deployment of web applications.
