You can choose which version of PHP each website uses, and adjust limits such as the maximum upload size or memory limit.
Tip: Use a currently supported PHP version for better speed and security. PHP 8.2 reaches end of life at the end of 2026, so we recommend PHP 8.3 or newer. Check that your themes and plugins support the new version first, and take a backup before switching.
Change the PHP version
Your cPanel will have one of the following tools under Software.
MultiPHP Manager
- Go to Software › MultiPHP Manager.
- Tick the domain(s) you want to change.
- Choose the version from the PHP Version menu and click Apply.
Inherit means the domain uses the server's default version.
Select PHP Version
- Go to Software › Select PHP Version.
- Choose from the Current PHP version menu. It saves automatically, or click Set as current.
- Use the Extensions tab to switch PHP extensions on or off (e.g.
intl,imagick).
Change PHP settings
In MultiPHP INI Editor (under Software), choose your domain in Basic Mode, adjust the values and click Apply. In Select PHP Version, use the Options tab instead.
