Around a month ago, version 5.3 of the popular scripting language PHP was released, and it is now available in the Control Center.
What's new in PHP 5.3
PHP 5.3 adds support for new features such as namespaces, closures, a native MySQL driver, and many others. Read more here.
Opt in per domain
PHP 5.3 is not enabled by default, because many web applications need to be modified or updated first. For example, warnings may arise about features that have been deprecated — functions that are being phased out and probably will not work in PHP 6.0. You can choose PHP 5.2 or PHP 5.3 for each domain individually, though new domains still default to PHP 5.2. This makes it easy to test whether a site works with PHP 5.3, with the option to quickly switch back to PHP 5.2 if any problems arise.
