Important
We highly suggest you to always using newest PHP version for your website. Besides permormance reasons (newer PHP version has much more higher performance and radically can speed-up your website loading time), its security reasons and support from developers. Older PHP versions are hard to carry on on newest operating systems with latest upgrades.
Important
PHP versions 5.6, 7.0, 7.1, 7.2, 7.3 are obsolete and no (or security) updates are released. We do not recommend using them, instead use one of the newer versions.

All PHP versions are available on all servers at all web hostings. There is no need to ask us to activate or move to another server. All you have to do is switch the version in the Hosting Control Panel.

How to change a PHP version for a website
Every hosting / website can use different PHP versions (within supported PHP versions). The change PHP version for a specific hosting you is simple fromHosting Control Panel.
In your Hosting Control Panel navigate to Sites and click on the website where you want to change PHP version on. In the PHP Version select a version you want to use and just click on the Save button.
