How can I get IP address from client side?

[andrew10181]

Thank you for your attention.

I am doing a project which is a website involving server and client side. It is a web-teaching system with video-conferencing. I am in trouble of how to detect client's IP address when the client click the web page to request to connect to server side without typing their own IP, for receiving video and audio. I really have no idea, can anyone help me?

Cheers!

I am assuming you have PHP experience, although you have only posted 2 messages on this site.

The PHP code used to detect the client's IP is:

<?php 
$client_ip = ( !empty($HTTP_SERVER_VARS['REMOTE_ADDR']) ) ? $HTTP_SERVER_VARS['REMOTE_ADDR'] : ( ( !empty($HTTP_ENV_VARS['REMOTE_ADDR']) ) ? $HTTP_ENV_VARS['REMOTE_ADDR'] : $REMOTE_ADDR ); 
?>

Now you can print the IP address..

<?php 
print($client_ip);
 ?>

My first post here..hope this helps you.
