Zend Guard is a PHP encoding and obfuscation product. It protects an application from unlicensed use, reverse engineering and redistribution by providing comprehensive licensing support.
That's pretty much why I use Zend Guard on my systems and for protecting my framework. Nobody should actually ever have access to the system and be able to look at and forbid copy any code but it's all about the saying "better save than sorry", right? There is apparently also some performance benefit but quite frankly I could not measure or see any difference; in either direction.
The documents in this chapter are my experience with Zend Guard and how to prevent or fix problems. Following is the list with the available documents
As with all the documents in my KB this is primarily about sharing my experience and not a complete reference guide for the product.
