This is a great service. For a few cents our development team can "compile" our php and html/php code to prevent users from messing with the logic and protect our intellectual property. Once you have an account you simply upload and compile your php code and then download the compiled version. There is a great free option that works for 8 hours that allow you to test a new script before committing to the final version. Compared to the "other" encoders out there this is the best, the cheapest and easiest to use. Basically it rocks!
