Sometimes you want to get the visitor’s IP address (e.g to show it to him or for logging purposes). This simple snippet does the job:

$ip = $_SERVER['REMOTE_ADDR'];

Also, if you have REGISTER_GLOBALS turned on on your server, you can use the shorter version:

$ip = @$REMOTE_ADDR;

Then you can easily use the variable called $ip for your needs.
