php怎么获取url并且不要参数?

测试网址:

http://afish.cnblogs.com/p/3941211.html?id=1

PHP代码实现如下：

//获取域名或主机地址
echo $_server['HTTP_HOST']."
"; #afish.cnblogs.com
//获取网页地址
echo $_SERVER['PHP_SELF']."
"; #/p/3941211.html
//获取网址参数
echo $_SERVER["QUERY_STRING"]."
"; #id=1
//获取用户代理
echo $_SERVER['HTTP_REFERER']."
";
//获取完整的url
echo 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
echo 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].'?'.$_SERVER['QUERY_STRING'];
#http://afish.cnblogs.com/p/3941211.html?id=1
//包含端口号的完整url
echo 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
#http://afish.cnblogs.com:80/p/3941211.html?id=1
//只取路径
$url='http://'.$_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"];
echo dirname($url);
#http://afish.cnblogs.com/p
