By "patch" I mean we installed the "PHP 4.2.0 to 4.2.2 patch" (file: http://www.php.net/do_download.php?download_file=php-4.2.0-to-4.2.2.patch.gz) available from php.net. This patch is described as the update to close the HTTP POST header parsing vulnerability discovered on July 21st (the "triggering" event for creation of the 4.2.2 version).. I assume from your response that you performed the Full PHP 4.2.2 install rather applying the Patch (as we did). If that is correct, then it does seem to confirm my belief that PHP 4.2.2 itself is not compatible with the Zend Encoded/Optimized files!

It is fully compatible. The only issue with the Optimizer and PHP 4.2.2, was that the Optimizer's installation program would not recognize PHP 4.2.2 as a supported PHP version. However, for people who already had PHP 4.2.1 installed and upgraded - this is not an issue at all, since as far as binary compatibility goes - the optimizer is fully compatible with 4.2.2. Either way, this installation issue was addressed as well, and the new package available on www.zend.com will recognize PHP 4.2.2 as well. You can take a look at phpinfo() to see whether the Optimizer was successfully loaded or not. If it wasn't, you can take a look at your server's error log for possible causes, or submit a trouble ticket on www.zend.com/helpdesk/. I'm not sure what was causing the access problems you had to www.zend.com - it hasn't been down since its last upgrade-related reboot 7 days ago. Zeev
