A surefire way to encrypt your source code and protect.
Editor: As mentioned earlier, obfuscation is a surefire way to encrypt your source code and protect it from being stolen. CodeTangler Pro is a PHP Obfuscator and encoder for solving this problem. CodeTangler will perform everything from the simplest methods such as stripping out Whitespace to encoding your source code into a labyrinth of tangled yet runnable code. You have the option to choose what you wish to do with your source code and how you wish to obfuscate it.

CodeTangler Pro can scan your source code files for all comments, variables, functions, and classes as well as the statistics of their occupation within the total source code. Scanning source code is necessary in order to obfuscate it later. Once your project is scanned, you may modify any functions, classes, and variables scanned as well as their corresponding obfuscated replacement values.
