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

how ip , port of client php?

i tried script below gives me ip address.

<?php print $_server['remote_addr']; ?> 

port defined in http server (apache or other , 80 or 443)

the php $_server variables can check @ : http://www.php.net/manual/en/reserved.variables.server.php

i sure : remote_addr' ip address user viewing current page.

but if server behind nat:

if serving behind proxy server, save time looking @ these $_server variables on machine behind proxy.

$_server['http_x_forwarded_for'] in place of $_server['remote_addr']

$_server['http_x_forwarded_host'] , $_server['http_x_forwarded_server'] in place of $_server['server_name']
