Zend Guard 6 | Zend by Perforce

December 2013

Encoding/obfuscation for PHP 5.4 is not compatible with PHP 5.3 and earlier releases, and vice versa. That is, a file encoded to run on PHP 5.3 will not be loaded on PHP 5.4 and vice versa. Workaround: Encode your application separately to run on PHP 5.3 and PHP 5.4.

Relative names do not work with --ignore and --exclude-file
Using inexact file names (different cases, / instead of \\, or not full paths) does not work with --ignore and --exclude-file (Windows only)
"Work only with encoded files" option does not work if it is not applied for all files
Extending stdClass gives a blank output when a file is encoded

Using mbstring.func_overload with obfuscation requires exporting functions that are overloaded.

Implementing PHP interfaces (such as Iterator) requires exporting interface methods
Autoloading does not work for obfuscated classes (due to different class names)
Obfuscating class and function names can break any code that accesses a function by string, such as calling a variable function like $func(), or calling a PHP internal function to access a class/function as a variable, such as call_user_func($func), etc.
--export-php may not automatically export some SPL iterator classes
