Basically, the Zend Engine is kind of like a macro scripting engine that PHP runs on top of. You can actually remove the Zend Engine and use it in other applications, like a macro engine for a work processing app, for instance.
The Zend Optimizer isn't a part of the Zend Engine or PHP; it's an extension that you can download from www.zend.com. It isn't part of the standard PHP build or distribution. To duplicate the error I posted, get PHP 4.2.1 and the Zend Optimizer. Install both, then follow the directions that accompany the ZO to enable the Optimizer. (It basically involves making a few changes to your php.ini file -- I believe the ZO setup script does this for you now.) After installing, start up PHP from a shell and you should get the error. If you're using PHP with a web server, check the server's error log.
