PHP runs most websites on our servers, and the version matters for both speed and security.
CHANGING IT
cPanel > MultiPHP Manager, tick the domain, choose the version, click Apply. The change is immediate, and each domain on the account can run a different version.
WHICH TO CHOOSE
Use the newest version your software officially supports. PHP 8.1 or 8.2 suits most current sites and is significantly faster than PHP 7.x. Running an unsupported version means no security patches, which is a genuine risk rather than a theoretical one.
Before switching, check your application's own compatibility screen. In WordPress that is Tools > Site Health.
TESTING AFTERWARDS
Load the homepage, an inner page, the admin area and any checkout. If you see a fatal error about deprecated functions or unexpected syntax, switch back one version immediately from the same screen, then update the software responsible before trying again.
MISSING EXTENSIONS
If an application reports a missing extension, enable it under Select PHP Version > Extensions. Commonly required ones are imagick, intl, zip, curl, gd, mbstring, soap and bcmath.
If something needs an extension not listed, open a ticket and we will advise whether it can be added.
