[Tutorial] How to grab IP adress with PHP

[flAmingw0rm]

Hello Support Forums,

In this tutorial I will show you how to grab someone's IP Adress when they visit a website.


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 Code:

<?php 
print ($_SERVER['REMOTE_ADDR'], "I'm Watching You!"); 
?>

Printing it to a File:

PHP Code:

<?php 
$ip = $_SERVER['REMOTE_ADDR']; 
$handle = fopen('ipaddresses.txt'', 'a+); 
fwrite($handle, $ip); fwrite($handle, "\n"); 
fclose($handle); 
?>

Now, you have to make a new text file and insert any of these codes or your own and save it as "anything.php".

Good luck.
