Installation is initiated either by downloading the product from www.zend.com or by the Zend IDE during its installation (it will install from the web).
Regardless of installation method, Zend Guard provides a standalone solution for encoding files as well as electronic licensing for protecting intellectual property.
To view the Zend Guard system requirements, go to: http://www.zend.com/products/zend_guard/system_requirements
Please note that some requirements may change from time to time.
Encoded files which have obfuscated local variables are only compatible with Zend Optimizer version 3.3 and above.
Encoded files which have obfuscated variables and also have obfuscated functions, classes and/or PHP Internal symbols require the latest version of Zend Optimizer (PHP5 and PHP 5.3 - Optimizer 3.3 and above).
Encoded files can be used with PHP 5, PHP 5.3 or greater.
Obfuscation of entities other than local, requires that the latest version of Zend Optimizer be installed. The Zend Optimizer is available for download free of charge, from the Zend Store, at: https://www.roguewave.com/zend-store/.
PHP files encoded with Zend Guard 5.0 or Zend Guard 5.5 require Zend Optimizer 3.3 (or greater) in order to run. Encoded files can be used with PHP 5 and PHP 5.3 (or greater).
Note:
Newer PHP language features and constructs should be run on PHP versions that support them. This is true for both encoded and non-encoded PHP files.
Windows - Double-click on self-extracting archive, and follow the instructions in the installation wizard.
Linux - Extract the downloaded tar.gz file: ZendGuard-5_5_x.tar.gz. As soon as the extraction is done, run the following extracted binary: ./ZendGuard-5_5_x.bin and follow the instructions in the installation wizard.
Mac - Extract the zip file double clicking on it. Double click on the archive directory in order to start the Zend Guard installation executable and follow the instructions in the installation wizard.
The Zend Guard Loader is a PHP extension that runs PHP scripts encoded by Zend Guard. The Guard Loader extension must be installed on each Web server that runs files that were encoded with, or use, Zend Guard licenses. The Zend Guard Loader translates encoded files to a format that can be parsed by the Zend Engine. This runtime process uses the Zend engine as a trigger to start the Zend Guard Loader component.
Note:
This procedure pertains only to users attempting to run files that were encoded with Zend Guard, and who do not have Zend Guard installed on their machine.
