Vật Giá Laravel (Lumen) 模型帮助轻松连接多个 MySQL 数据库（主从）。

功能

• 通过模型主从连接多个数据库
• 根据权重配置随机连接一个数据库从服务器

使用

配置如下

<?php

return [

    'default' => 'master',

    'connections' => [
        'master' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST'),
            'port' => env('DB_PORT'),

您的模型需要继承自 VatGia\Model\Model

如何更改数据库

MyModel::setConnection('master')
MyModel::setConnection('slavses')
MyModel::setConnection('slavses.web31')
