    Thanks for your great work.

    I have a particular requirement for which I have not been able to find a solution.

    I already Minify my JS files satisfactorily but my inline jQuery and Javascript is invariably generated by a PHP Class. I need a PHP Obfuscation Class which compresses and obfuscates the string containing the collection of functions and Doc Ready code just before it is “return”ed or “echo”ed back to the browser.

    The closest I have come is phpJSO but this relies on the existence of a js file and is now quite old. Before I set about writing one, I wondered if you knew of such a Class?

      Hi webcliq, interesting idea, coding quite a bit of dynamic PHP myself i can see how useful it could be. Not seen anything good out there, might have a go myself at coding something, stay tuned. Sam
