Last June, we announced that we were no longer supporting PHP4. Following the announcement, many customers requested a deadline for the support of PHP 5.3 and 5.4. We had already planned putting more time in testing these versions on our Panelbox platform, and see if we could simultaneously support 5.2 (the current version), alongside 5.3 and 5.4. The testing period is now complete, and we have finalized the integration of the latest versions of PHP on our servers!
What does this mean?
The version of PHP you are using has certain variables, logic, or features that may not exist in previous versions. When you use a Content Management System (CMS) such as WordPress, Joomla, Magento, etc., they have predetermined features and settings that allows the whole web-program to function. Newer versions of these applications might have problems with previous PHP versions.
When a website is created, it is programmed with a version in mind. If that version is unavailable on the server you are hosted, the website might not be optimal, or functional at all. Therefore, choosing the right version of PHP is crucial, and you now have the opportunity to choose between 5.2, 5.3 and 5.4.
