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://获取域名或主机地址 echo $_SERVER[&#39;HTTP_HOST&#39;]."<br>"; #local
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:
//获取域名或主机地址 
echo $_SERVER['HTTP_HOST']."<br>"; #localhost

//获取网页地址 
echo $_SERVER['PHP_SELF']."<br>"; #/blog/testurl.php

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

//获取用户代理 
echo $_SERVER['HTTP_REFERER']."<br>"; 

//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/blog/testurl.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/blog/testurl.php?id=5

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





构造地址栏参数  

  
<?php
$data  = array( 'foo' => 'bar' ,
               'baz' => 'boom' ,
               'cow' => 'milk' ,
               'php' => 'hypertext processor' );

echo  http_build_query ( $data ) .  "\n" ;
echo  http_build_query ( $data ,  '' ,  '&amp;' );

?>

以上例程会输出:

foo=bar&baz=boom&cow=milk&php=hypertext+processor
foo=bar&amp;baz=boom&amp;cow=milk&amp;php=hypertext+processor
