获取当前url（收集）

<?php
 // 说明：获取完整URL
 
function curPageURL() 
{
     $pageURL = 'http';
 
    if ($_SERVER["HTTPS"] == "on") 
    {
         $pageURL .= "s";
     }
     $pageURL .= "://";
 
    if ($_SERVER["SERVER_PORT"] != "80") 
    {
         $pageURL .= $_SERVER["SERVER_NAME"] . ":" . $_SERVER["SERVER_PORT"] . $_SERVER["REQUEST_URI"];
     } 
    else 
    {
         $pageURL .= $_SERVER["SERVER_NAME"] . $_SERVER["REQUEST_URI"];
     }
     return $pageURL;
 }
 ?> 


     定义该函数之后就可以直接调用了：

<?php
 // 说明：获取无参数URL
 
function curPageURL() 
{
     $pageURL = 'http';
 
    if ($_SERVER["HTTPS"] == "on") 
    {
         $pageURL .= "s";
     }
     $pageURL .= "://";
 
    $this_page = $_SERVER["REQUEST_URI"];
     
    // 只取 ? 前面的内容
     if (strpos($this_page, "?") !== false) 
        $this_page = reset(explode("?", $this_page));
 
    if ($_SERVER["SERVER_PORT"] != "80") 
    {
         $pageURL .= $_SERVER["SERVER_NAME"] . ":" . $_SERVER["SERVER_PORT"] . $this_page;
     } 
    else 
    {
         $pageURL .= $_SERVER["SERVER_NAME"] . $this_page;
     }
     return $pageURL;
 }
 ?>

<?php
 // 说明：获取无参数URL
 
function curPageURL() 
{
     $pageURL = 'http';
 
    if ($_SERVER["HTTPS"] == "on") 
    {
         $pageURL .= "s";
     }
     $pageURL .= "://";
 
    if ($_SERVER["SERVER_PORT"] != "80") 
    {
         $pageURL .= $_SERVER["SERVER_NAME"].":" . $_SERVER["SERVER_PORT"] . $_SERVER['PHP_SELF'];
     } 
    else 
    {
         $pageURL .= $_SERVER["SERVER_NAME"] . $_SERVER['PHP_SELF'];
     }
     return $pageURL;
 }
 ?>

function request_uri()
 {
     if (isset($_SERVER['REQUEST_URI']))
     {
         $uri = $_SERVER['REQUEST_URI']; 
    }
     else
     {
         if (isset($_SERVER['argv']))
         {
             $uri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['argv'][0];
         }
         else
         {
             $uri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['QUERY_STRING'];
         }
     }
     return $uri;
 }
 ?>
