为什么我打印不出来$_SERVER['PATH_INFO']呢
即然是全局数组,按说应该能啊,但是var_dump后是一个NULL,啥回事呢,
------解决思路----------------------
$_SERVER 是超全局数组,并不表示他的每一项都存在
比如 $_GET、$_POST 不都是有条件有值的吗
------解决思路----------------------
包含由客户端提供的、跟在真实脚本名称之后并且在查询语句(query string)之前的路径信息,如果存在的话。例如,如果当前脚本是通过 URL http://www.example.com/php/path_info.php/some/stuff?foo=bar 被访问,那么 $_SERVER['PATH_INFO'] 将包含 /some/stuff。
