# ZMUtil 杂项工具类
|
|
|
|
|
|
|
|
|
|
|
|
调用前先 use：`use ZM\Utils\ZMUtil;`
|
|
|
|
|
|
|
|
|
|
|
|
## ZMUtil::stop()
|
|
|
|
|
|
|
|
|
|
|
|
停止框架运行。
|
|
|
|
|
|
|
|
|
|
|
|
## ZMUtil::reload()
|
|
|
|
|
|
|
|
|
|
|
|
重载框架，这会断开所有到框架的连接和重载所有 `src/` 目录下的用户源码并重新加载所有 Worker 进程。
|
|
|
|
|
|
|
|
|
|
|
|
## ZMUtil::getModInstance()
|
|
|
|
|
|
|
|
|
|
|
|
根据类名称拿到此类的单例（前提是目标的类的构造函数为空）。
|
|
|
|
|
|
|
|
|
|
|
|
```php
|
|
|
|
|
|
class ASD{
|
|
|
|
|
|
public $test = 0;
|
|
|
|
|
|
}
|
|
|
|
|
|
ZMUtil::getModInstance(ASD::class)->test = 5;
|
|
|
|
|
|
```
|

|
## ZMUtil::getReloadableFiles()
|
|
|
|
|
|
|
|
|
|
|
|
返回可通过热重启（reload）来重新加载的 php 文件列表。
|
|
|
|
|
|
|
|
|
|
|
|
以下是示例模块下的例子（直接拉取最新的框架源码并运行框架后获取的）。

|
> 为什么不能重载所有文件？因为框架是多进程模型，而重载相当于只重新启动了一次 Worker 进程，Manager 和 Master 进程未重启，所以被 Manager、Master 进程已经加载的 PHP 文件无法使用 reload 命令重新加载。详见 [进阶 - 进程间隔离](/advanced/multi-process/#_5)。
