When using PHP and the environment variables you can only grab the IP Address of the client that is accessing your PHP file.

Hence that would be your computer.

By saving the IP addresses and the timestamps in a database, you can keep a log of what ip addresses accessed that page and at what time.

Thanks for your reply! Sample coding would be very useful for me.

You can use this:
$ip = $_SERVER['REMOTE_ADDR'];
