How to quickly build laravel

Laravel is a popular PHP framework that provides convenient development tools and excellent performance, making it the first choice for many web developers. For developers who want to quickly learn and build Laravel projects, the following article will provide you with some basic guidance.

Environment setup

Before you start using Laravel, make sure that your computer has the two tools PHP and Composer installed. PHP is the core language that Laravel relies on, and Composer is PHP's dependency manager. After installing Composer, you can install Laravel through the following command:

composer global require laravel/installer

After the installation is completed, you can check whether the installation is successful through the following command:

laravel --version

Create project

In the installation After completing Laravel, you can create a new Laravel project with the following command:

laravel new my-project

where my-project is the name of the project you want to create. Laravel will create a new project in this directory.

You can also use the following command to create a Laravel project:

composer create-project --prefer-dist laravel/laravel my-project

This method will install Laravel from Packagist through Composer, and then create a new project in the my-project directory.

Start the project

After the Laravel project is created, you can use the following command to start the project:

php artisan serve

This command will start a Web server locally and listen to port 8000. Enter http://localhost:8000 in the browser to access the site.

Configuring the database

Laravel uses the SQLite database by default, but when we need to use other types of databases, we need to configure it accordingly. In Laravel, the database configuration file is located in config/database.php. We can configure the database here.

You can see a configuration similar to this in config/database.php. This is the default SQLite configuration:

'sqlite' => [
    'driver' => 'sqlite',
    'url' => env('DATABASE_URL'),
    'database' => env('DB_DATABASE', database_path('database.sqlite')),
    'prefix' => '',
    'foreign_key_constraints' => env('DB_FOREIGN_KEYS', true),
],

We can replace this configuration with the configuration of other types of databases, such as MySQL . For example, the following is a MySQL configuration:

'mysql' => [
    'driver' => 'mysql',
    'url' => env('DATABASE_URL'),
    'host' => env('DB_HOST', '127.0.0.1'),
    'port' => env('DB_PORT', '3306'),
    'database' => env('DB_DATABASE', 'laravel'),
    'username' => env('DB_USERNAME', 'root'),
    'password' => env('DB_PASSWORD', ''),
    'unix_socket' => env('DB_SOCKET', ''),
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
    'prefix' => '',
    'prefix_indexes' => true,
    'strict' => true,
    'engine' => null,
    'options' => extension_loaded('pdo_mysql') ? array_filter([
        PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
    ]) : [],
],

In the above configuration, the fields that need to be modified include host, port, database, username and password. These fields need to be set to your own database configuration.

Creating Controllers and Views

Creating a controller in Laravel can be done with the following command:

php artisan make:controller HomeController

Here a controller called HomeController is created. The role of the controller is to accept the user's request and return a response.

When you need to switch views in the controller, you can create a view file through the following command:

php artisan make:view home

A view named home is created here, which can be rendered in HomeController through the following code Home view:

return view('home');

In the web.php file, you can use the following code to bind the URL and the controller:

Route::get('/', 'HomeController@index')->name('home');

The above code binds the homepage (/) and the index method in HomeController together and use home as the name. Next, add the index method in the controller:

public function index()
{
    return view('home');
}

Here is a simple HomeController code that returns a home view:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class HomeController extends Controller
{
    public function index()
    {
        return view('home');
    }
}

Conclusion

Of course, in actual development, more in-depth study and understanding are needed to better use Laravel for development.
