这句判断的意义何在
if(isset($_SERVER['HTTP_X_REWRITE_URL'])){
$_SERVER['REQUEST_URI'] = $_SERVER['HTTP_X_REWRITE_URL'];
$___s = explode(".",$_SERVER['REQUEST_URI']);
$____s = explode("?",$_SERVER['REQUEST_URI']);
$_SERVER['PATH_INFO'] = $____s[0];
$GLOBALS['is_iis'] = true;
}
如果重定向了,那么..................
------解决思路----------------------
IIS环境下首先域名重定向用$_SERVER[“HTTP_X_REWRITE_URL”]代替$_SERVER[‘REQUEST_URI’],apache环境则相反。
看这段代码是为了屏蔽在不同环境下$_SERVER['REQUEST_URI']的值出现差异的情况，代码中可能会用到这个全局变量来路由
