The improvements to PHP 5.3.3 should have no impact on existing code; however there are a few incompatibilities and new features that are worth noting:

  1. Zend Optimizer is no longer supported in PHP 5.3. Customers making use of Zend are required to change their Zend code to target the Zend Guard Decoder runtime, which is supported by PHP 5.3.3. For more information on this, visit the Zend site.

  2. register_globals and magic_quotes_gpc have reached end-of-life. Although still supported by PHP 5.3.3, they will be removed in future versions. Dependency on these features should be avoided in the long term.

  3. display_errors is now by default switched off in PHP 5.3.3 where it was by default on for PHP 5.2.6. This feature can be enabled via a ‘.htaccess’ file on PHP 5.3.3.

For further information regarding migrating to PHP 5.3, visit the PHP site. If you have any queries, please don’t hesitate to contact .(JavaScript must be enabled to view this email address).
