After downloading abt 4 obfuscators for php, i realise they all can be easily reverse engineered. the protection is not thorough.

So i created a free high end obfuscator for php (Phplocker). Its 100% free (less than 3kb) and very good for securing your code if you dont want people to modufy or edit it.
download at: http://www.afrisoft.org/ng/index.php/downloads
Phplocker encodes, obfuscates and encrypts PHP code to make the output difficult to understand or reverse engineer. The application requires no pre-modifications to your code, no addition of files to your project and no additional components on your server. This product allows for total encoding of everything between your opening php tag (<?php or <?) and your closing php tag ( ?>.

please try it out and report any bugs or suggest improvements. You'll definitely need it for your php projects.
