javascript实现：
top.location.href 顶级窗口的地址
this.location.href 当前窗口的地址



PHP实现：http://localhost/PHP/XX.php?id=5

//获取域名或主机地址
echo $_SERVER['HTTP_HOST']; #localhost

//获取网页地址
echo $_SERVER['PHP_SELF']; #/PHP/XX.php

//获取网址参数
echo $_SERVER["QUERY_STRING"]; #id=5

//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://localhost/PHP/XX.php?id=5

//包含端口号的完整url
echo 'http://'.$_SERVER['SERVER_NAME'].':'.$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
#http://localhost:80/PHP/XX.php?id=5

//只取路径
$url='http://'.$_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"];
echo dirname($url);
#http://localhost/PHP
