代码如下：
<?php
// php 获取当前访问的完整url
function GetCurUrl() {
$url = 'http://';
if(isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') {
$url = 'https://';
}
// 判断端口
if($_SERVER['SERVER_PORT'] != '80') {
$url .= $_SERVER['SERVER_NAME'] . ':' . $_SERVER['SERVER_PORT'] . ':' . $_SERVER['REQUEST_URI'];
} else {
$url .= $_SERVER['SERVER_NAME'] . ':' . $_SERVER['REQUEST_URI'];
}
return $url;
}
