1 Changes in Zend Guard from version 5.5 to 6.0
=====================================================
* Full support for PHP 5.4
* Dropped Support for PHP 5.2 ( Guard 5.5 should be used )
================================
2. Known issues and Limitations
================================
General:
--------
* 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.
Encoding:
---------
* 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
Obfuscation:
------------
* 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
