How can I get the IP address and port of a client with PHP?

How do I get the IP and port of a client with PHP?

I tried the script below but it only gives me the IP address.

<?php print $_SERVER['REMOTE_ADDR']; ?>

Answer

Port is defined in http server (Apache or other and mostly it is 80 or 443)

The php $_SERVER variables you can check at : http://www.php.net/manual/en/reserved.variables.server.php

I am sure that : REMOTE_ADDR' The IP address from which the user is viewing the current page.

But if your server is behind NAT:

If you are serving from behind a proxy server, you will almost certainly save time by looking at what these $_SERVER variables do on your machine behind the proxy.

$_SERVER['HTTP_X_FORWARDED_FOR'] in place of $_SERVER['REMOTE_ADDR']

$_SERVER['HTTP_X_FORWARDED_HOST'] and $_SERVER['HTTP_X_FORWARDED_SERVER'] in place of $_SERVER['SERVER_NAME']
