December 2013Zend is pleased to announce the release of Zend Guard 6.0! You can download this release from: http://www.zend.com/en/products/guard/downloads ================== Table of Contents: ==================1. Changes in Zend Guard 2. Known Bugs 3. Installation Instructions 4. System Requirements ===================================================== 1. Changes in Zend Guard ===================================================== 1.1 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 encodedObfuscation: ------------ * 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============================ 3.
