在本机开发时是没有异常的，部署到服务器就各种问题了，REQUEST_URI的参数明明是有值的，但是QUERY_STRING却是空的...orz
在本机开发时是用apache，部署是用ngnix难道和配置有关？

]刚发现只是被隐藏index.php才找不到$_GET的值，以*.php结尾的可以正常取到$_GET的值...
phpinfo();
看看是否有value
在看看php.ini 中：variables_order 的值。 修改成为这样就OK了
variables_order="EGPCS"是有可能跟你的nginx 配置有关的。
我使用nginx 配置的时候遇到过这样的问题，POST 数据是OK 的，但是GET 却获取不到数据。
当时的原因始我用的 try_files，在try_files 中的uri 后面参数没写对引起的错误。
