[Tutorial] How to grab IP adress with PHP

[Unwanted]

How would you exclude a specific IP from being detected?

Add an if statement to filter out the IP.
Then log anything that isn't equal to the IP specified.

PHP Code:

<?php
$ip = $_SERVER['REMOTE_ADDR'];
$filterip = "localhost";

if ($ip == $filterip)
{
echo("Welcome!");
}
else
{
echo("You are not welcome here!");
}
?>

Hope this helped
