如何从编码过的url中通过get获取参数
http://域名/?id%3D3%26server_id%3Ds1%26sign%3Df44f5ac51cbc95e13102cd5657082dc6

想从这个链接中$_GET到id  server_id  和 sign这三个参数
接收参数的php文件需要如何先处理一下这个链接呢

能不能稍微具体点儿
本人新手菜鸟,谢谢

通过$_GET应该是能获取的

需要获取的参数都是动态的,每次……

<br />$a = explode('&', $QUERY_STRING);<br />$i = 0;<br />while ($i < count($a)) {<br />    $b = split('=', $a[$i]);<br />    echo 'Value for parameter ', htmlspecialchars(urldecode($b[0])),<br />         ' is ', htmlspecialchars(urldecode($b[1])), "<br />\n";<br />    $i++;<br />}    <br />
Copy after login

这个是手册的例子 参考下吧
------解决方案--------------------
var_dump(($_SERVER['REQUEST_URI']));
var_dump(($_SERVER['SCRIPT_NAME']));
------解决方案--------------------
$str = urldecode($_SERVER['QUERY_STRING']);<br />parse_str($str, $get);<br />var_dump( $get['sign'] );
Copy after login
