How to grab IP address with PHP

Today I’ll be showing you how to grab somebodies IP address when they visit a page. The variable to use is $_SERVER['REMOTE_ADDR'] - It’s that simple. You can use it for just about anything, here are a few examples. Printing the Users IP Address: <?php print ($_SERVER['REMOTE_ADDR'], "I'm Watching You!"); ?> Printing it to a File: <?php $ip = $_SERVER['REMOTE_ADDR']; $handle = fopen('ipaddresses.txt'', 'a+); fwrite($handle, $ip); fwrite($handle, "\n"); fclose($handle); ?> All you have to do, is to make a text file and insert any of these codes or one of your own and save it as anythingyouwant.php Then upload it to your website and it'll do the trick :P The Possibilities for what you can use this to are endless. Good luck :D
