What are the key features of YAPHPO that makes it ideal for your PHP obfuscation?

• It uses the PHP tokenizer itself: YAPHPO does not attempt to parse your code. Instead, your code gets passed to PHP itself which analyses it, marks it up then returns it for YAPHPO to do its work.

• Obfuscation of constants: a feature that we have not found in any of the other PHP obfuscators.

• The powerful 'include' and 'exclude' lists. Choose exactly which files, directories, functions, variables, classes and so on to obfuscate.

• Exclude those that you import from your CMS or database library, for example, as well as any functions that you wish to make available to other developers.

• Step-by-Step obfuscation: throughout the process you are easily able to ensure that it is working as expected. If you like, you can run file comparisons between the results of each step of the obfuscation.

• Output is valid PHP: therefore, there is no requirement for any particular extensions to be installed on the server that your code is going to run on.

• It's Free and licensed under the GPL. Just to allay any fears: no, that does not mean that your program will have to be GPL, just because you use YAPHPO. Yes, you can use YAPHPO on your commercial products without any fear of being required to release the code to anyone.
