Protect Source

[Echilon]

I'm looking for a way to obfuscate the source of a project I'm developing, and also to lock the script to a specified domain. I was thinking of using $_SERVER['HTTP_HOST'] somehow, but I'm not sure how I'd make it work. Does anyone have any suggestions?

Well, here is a website that will obfuscate your code: http://sls.web.psi.ch/goto.php/duo/obfuscate.php

But, I depending on your needs you may want to have a more professional application for the purpose: http://www.gridinsoft.com/protect.php

As for ensuring the program is running on the correct server just use something like:

if ($_SERVER['HTTP_HOST'] != "mydomain.com") {
    die ("This is the wrong domain");
}

You could use it at the top of each page or as an include file.
