You can:

1. First put this code to the top of your PHP scripts you want to encode:

<?php
$s_host_l = strtolower($_SERVER['HTTP_HOST']);
if (($s_host_l != "site.com") && ($s_host_l != "www.site.com")) { echo "wrong server"; exit(); }
?>

Note: site.com is the website that you'll allow your scripts to run.

2. Zip all your script you want to encode.
3. Go
http://www.ioncube.com/online_encoder.php
and upload your zip file then encode with ionCube encoder.

It is very effective way to protect your scripts.
You'll need Ioncube Loader to be installed to the server that your scripts will run on.
It is also very simple. Just look to the page http://www.ioncube.com/loaders.php
