I need to encrypt some PHP source that I\'ve released to the public.
Is this possible? Can PHP be \"compiled\" ?
I would say try ionCube also - they're one of the longest established and successful creators of PHP Encoding software. We use them for our Web development projects and while the need to install a "Loader" is a bit of a downside, they now provide the Loader Wizard script which we bundle to users and it gives them step by step instructions.
Also, I've always found their support to be more than helpful :)
