With this PHP IP Logging Snippet, it allows you to LOG the visitors IP address's which visit your website, and all you have to do is the following:

• Create A TXT File Called (ips.txt)
• Upload It To Your Server
• CHMOD The (ips.txt) File To 777
• The IP's Will Then Be Logged At (http://www.yourdomain.com/ips.txt)

<?php

$v_ip = $REMOTE_ADDR;
$v_date = date("l d F H:i:s");

$fp = fopen("ips.txt", "a");
fputs($fp, "IP: $v_ip - DATE: $v_date\n\n");
fclose($fp);

?>
