Encode And Optimize PHP: Obfuscate and compact PHP source files

This class can obfuscate and compact PHP source code files.

It can process a PHP source code file and replace characters in text strings by the corresponding hexadecimal representation, making the code harder to read and understand what it does.

It can also compact the PHP source code files by eliminating comments, white spaces and empty line, making the output smaller and even harder to read.
