This happens because the global user object is not available in the sess_write() session handler.

发生这种情况是因为在 sess_write() 会话处理程序中无法使用全局用户对象。

It is very similar to APC in function and sports a user cache component, as well as a built-in session handler to leverage Wincache directly as a session handler.

它在功能上非常类似于apc，且支持一个用户缓存组件，以及一个内置会话处理程序，以将Wincache作为一个会话处理程序直接加以利用。
