在PHP检测浏览器退出
问题描述：
我已经看过几个主题（这里和放大器;谷歌）关于PHP检测浏览器的退出和IM没有真正的更清楚如何做到这一点。
I have looked at a few topics (here & google) regarding detecting browser exit in php and im not really any clearer on how to do so.
我试过 register_shutdown_function 在PHP但是当我刷新浏览器页面正在执行偶数。
I tried the register_shutdown_function in PHP but that was executing even when i refreshed the browser page.
谁能帮助？
在此先感谢

PHP是一个服务器端语言。浏览器事件通过DOM事件来处理。在onunload的或onbeforeunload事件，发送一个AJAX调用的PHP文件。
PHP is a server side language. Browser events are handled by DOM events. On "onunload" or "onbeforeunload" events, sending an AJAX call to a PHP file.
And in this other question there is a flavored explanation of what I'm saying.
