PHP如何检索远程ip地址？

Question

My scenario is I have binded one ip address with my local ip address i.e. AAA.BBB.CCC.DDD binded to XXX.YYY.ZZZ.AAA

Local IP: XXX.YYY.ZZZ.AAA
Remote IP: AAA.BBB.CCC.DDD

I have binded Remote IP to my Local Ip.

So my question is what if I have to get binded Remote Ip address using REMOTE_ADDR method instead of Local (my real) ip address.

Right now it is returning my local ip address.

Please help...

Use $_SERVER["REMOTE_ADDR"] like this

$remoteIp = $_SERVER['REMOTE_ADDR'];
if (array_key_exists('HTTP_X_FORWARDED_FOR', $_SERVER)) {
    $remoteIp = array_pop(explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']));
}

$_SERVER in php.net
