非 Laravel 项目使用 Eloquent

什么是 Eloquent ？

Eloquent ORM 提供了漂亮、简洁的 ActiveRecord 实现来和数据库交互。每个数据库表都有一个对应的”模型“用来与该表交互。你可以通过模型查询数据表中的数据，并将新记录添加到数据表中。

Eloquent 使用方法

安装 Eloquent

使用 Composer 来安装

1

composer require illuminate/database

配置数据库连接

新建 bootstrap.php，内容如下：

<?php

require __DIR__.'/../vendor/autoload.php';

use Illuminate\Database\Capsule\Manager as Capsule;

$capsule = new Capsule;

$capsule->addConnection([
    "driver" => "mysql",
    "host" => "127.0.0.1",
    "database" => "test",
    "username" => "root",
    "password" => "root",
    'charset' => "utf8mb4",
    'collation' => "utf8mb4_general_ci"
]);

$capsule->setAsGlobal();
$capsule->bootEloquent();

创建表 Migration

新建 migrate-comments.php

use Illuminate\Database\Capsule\Manager as Capsule;

Capsule::schema()->create('comments', function ($table) {
       $table->increments('id');
       $table->string('nickname');
       $table->string('content');
       $table->timestamps();
   });

访问 migrate-comments.php 进行迁移

    public $timestamps = true;
}

这里实现了简单的示例，更多特性还需看 Laravel Eloquent 文档。
