IP Grabber
Tue, 2007/06/12 - 10:29 — Jamie
This simple script allows you to return the users IP address using getenv variables. Originally posted on 227net and works in PHP4 and up. Note: This will return your internal IP when running through a local server.
<?php
// ip_grabber
/* Note: You can also check against $_SERVER variables not included in this script */
function ipGrabber() {
if(getenv("HTTP_CLIENT_IP")) {
$ip = getenv("HTTP_CLIENT_IP");
} elseif (getenv("HTTP_X_FORWARDED_FOR")) {
$ip = getenv("HTTP_X_FORWARDED_FOR");
} else {
$ip = getenv("REMOTE_ADDR");
}
return $ip;
}
/* Example usage */
echo "<p>Your IP is: <b>". ipGrabber() ."</b>.</p>";
?>
