Knowledge Base Overview

I see a lot of questions about Zend Optimizer for PHP 5.4 in my analytics, hence I think it is a good idea when I address this topic here with an answer to this burning question.

Use Zend Guard Loader and PHP 5.3

First off real quick what you probably already know is that Zend Optimizer does not work with PHP 5.4. In fact Zend Optimizer also does not work on PHP 5.3. However, for PHP 5.3 you will have to use another decoder which is named Zend Guard Loader and this will work with PHP 5.3. Unfortunately that is the only version Zend Guard Loader supports and still not PHP 5.4.

Supported decoder for PHP 5.4

As of today 2/8/2013 and a short visit to the Zend download page for the decoders tells me that there is still no support for PHP 5.4 available. Also looking around their website I still see no sign or information when we can expect support PHP 5.4.

The only solution or latest version and combination that works is running PHP 5.3 with Zend Guard Loader. There's also IonCube but the latest info as of today is that they also don't have a 5.4 supported version yet.
