$_SERVER的问题,我说为什么一直url重写失败,去不掉index.php
有的主机url重写后
$_SERVER['PATH_INFO']会消失,
取而代之的是
$_SERVER["ORIG_PATH_INFO"]
从而导致,根据$_SERVER['PATH_INFO']判断来去掉index.php会失效
我只是发现了这个现象,却不明白原理是为什么?
------解决方案--------------------PATH_INFO is missing but ORIG_PATH_INFO is there with the information PATH_INFO was supposed to have.
So the php code had to be changed to check for $_SERVER['ORIG_PATH_INFO'] when $_SERVER['PATH_INFO'] is absent
