Every plan supports PHP 7.4 through 8.3, and you can run different versions on different sites in the same account, useful if you're maintaining an older project alongside something newer.
MultiPHP Manager
Open MultiPHP Manager
In cPanel, go to Software → MultiPHP Manager. You'll see every domain and subdomain on the account listed with its current PHP version.
Select the domain(s)
Check the box next to whichever domain you want to change, you can select multiple at once if they should all move together.
Choose a version and apply
Pick a version from the dropdown at the top and click Apply. The change takes effect immediately, no restart or downtime.
Fine-tuning with MultiPHP INI Editor
For per-site settings like memory_limit, upload_max_filesize, or max_execution_time, use MultiPHP INI Editor in the same section. Switch to Editor Mode for a domain to edit its php.ini directives directly.
Test before you switch a live site
Older plugins and libraries can break on a newer PHP version. If you're on Pro or above, spin up a staging copy first and confirm nothing throws deprecation errors before applying the change to production.
