PHP的 - 取消$这个 [英] php - unset $this

问题描述

我做了一个类似文件包装的类。当用户调用delete方法时，我想取消设置对象（实际上是$ this）。有没有办法（解决方法）来做到这一点？该手册说不，没有办法...

解决方案

据我所知，没有办法摧毁一个从类本身内部的类实例。

  $ myClass = new fooBar（）; 
 unset（$ myClass）; 
  

有点相关：做以上操作会自动调用任何现有的 __ destruct（）类的魔术方法，所以你可以做任何额外的清理。 更多信息

I've made a class that acts like an file wrapper. When user call delete method, i want to unset the object (actually $this). Is there a way (workaround) to do that? The manual said no, there is no way...

解决方案

As far as I know, there is no way to destroy a class instance from within the class itself. You'll have to unset the instance within its scope.

$myClass = new fooBar();
unset($myClass);

Somewhat related: Doing the above will automatically call any existing __destruct() magic method of the class so you can do any additional cleanup. More info
