IP locator websites..?

[Proof]

There are several pre-defined functions in PHP.

To be honest I would just use a site rather than make one..

I was more wondering about the information gathered from the IP address. Such as ISP, Host, City, Country, Proxy, etc...

IP address

PHP Code:

<?php $_SERVER['REMOTE_ADDR'] ?>

Host

PHP Code:

<?php $_SERVER['REMOTE_HOST'] ?>

Browser info..

PHP Code:

<?php $_SERVER['HTTP_USER_AGENT'] ?>
