How to use laravel

Laravel 简介

Laravel 是一种免费开源的 PHP Web 框架,以其优雅的语法和强大的功能而闻名。它旨在创建和维护复杂 Web 应用程序。

入门 Laravel

1. 安装 Laravel

  • 确保已安装 PHP 7.3 或更高版本。
  • 使用 Composer 安装 Laravel:composer global require laravel/installer
  • 创建一个新项目:laravel new project-name

2. 启动开发服务器

  • 导航到项目目录:cd project-name
  • 启动开发服务器:php artisan serve
  • 应用程序将在 http://localhost:8000 运行。

3. 创建模型

  • 模型代表应用程序中的数据。
  • 使用 Artisan 命令创建模型:php artisan make:model ModelName

4. 创建控制器

  • 控制器处理用户请求并与模型交互。
  • 使用 Artisan 命令创建控制器:php artisan make:controller ControllerName

5. 定义路由

  • 路由将 URL 映射到控制器方法。
  • routes/web.php 中定义路由:
Route::get('/route-name', 'ControllerName@method');

6. 渲染视图

  • 视图是应用程序的用户界面。
  • 在控制器中使用 view() 方法渲染视图:
return view('view-name');

7. 迁移数据库

  • Laravel 使用迁移来管理数据库架构。
  • 使用 Artisan 命令创建迁移:php artisan make:migration create_table_name
