Known issues and Limitations

  • Encoding/obfuscation for PHP 5.3 is not compatible with PHP 5.2 and earlier releases, and vice versa. That is, a file encoded to run on PHP 5.3 will not be loaded on PHP 5.2 and vice versa. Workaround: Encode your application separately to run on PHP 5.3 and PHP 5.2.
User Interface
  • Zend Studio cannot initiate a few instances of Zend Guard and can integrate only with a new one.
  • 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.
Class Obfuscation
  • 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
