本文实例讲述了php获取客户端IP及URL的方法。分享给大家供大家参考，具体如下：
function getonlineip(){//获取用户ip
if($_SERVER['HTTP_CLIENT_IP'])
{
$onlineip=$_SERVER['HTTP_CLIENT_IP']; //用户IP
}
else if($_SERVER['HTTP_X_FORWARDED_FOR'])
{
$onlineip=$_SERVER['HTTP_X_FORWARDED_FOR']; //代理IP
}
else
{
$onlineip=$_SERVER['REMOTE_ADDR']; //服务器IP
}
return $onlineip;
}
function curPageURL()//获取完整的url
{
$pageURL = 'http';
if ($_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;
