POBS

POBS, stands for PHP Obfuscator/Obscurer, is a free and open PHP program that makes PHP sourcecode almost impossible to read and edit for ordinary users. It is a simple way to protect your PHP sourcecode from people who whould like to adjust it or who would like to know the inner workings of it. It allows you to deploy your application and feel pretty safe about it. POBS works by replacing User-defined functionnames, variables and constants with a MD5 key of 8 characters. It really removes information that humans would like to have but computers don't care about. It's not ideal but quite a good option in my idea. Advantages include: Really removes information from your sourcecode; Hard to reverse-engineer; Cross-platform, cross PHP version; Open Source. So it can be adjusted to your own needs; Works with PHP cachers like APC and ZEND Cache; and Works with Zend Encoder.
