Summary

You've spent months, years, developing the ultimate PHP application. It's time to take your product to market, but you want to make sure that all your hard work isn't going to be ripped off.

There are 3 ways to protect your PHP scripts: obfuscation, encoding/encryption, and pre-compilation. Most commercial products provide a combination of all 3 methods of protection.
