一 原理
laravel 里使用illuminate/config。 illuminate/config composer 地址illuminate/config - Packagist illuminate/config github 地址:GitHub - illuminate/config: [READ ONLY] Subtree split of the Illuminate Config component (see laravel/framework) 根据 illuminate/config 源码显示 illuminate/config/Repository.php 仅继承Illuminate\Contracts\Config\Repository没有其他操作。
所以编写Myconfig.php相同代码没有加入 illuminate/config。也可以直接执行命令添加。
composer require illuminate/config:版本
通过查看laravel源码发现先加入容器再重写容器中绑定的对象。
之所以不能直接绑定操作后的对象因为bind()、bindIf()等相关方法中被绑定的数据不能传对象而instance()没有此限制所以能传设置参数后的对象。
数据库管理对象构造传入容器对象会自动获取config对应参数。之后可以直接查询。
例子里对于设置容器后处理配置文件的流程与laravel不同。laravel中更复杂也更完善。
二 代码

- config/database.php
- Myconfig.php
