Different applications need different PHP versions. WordPress and most modern software run best on a recent, supported version. DirectAdmin lets you switch the PHP version for your site in a few clicks. Here is how.
Why the PHP version matters #
- Newer versions are faster and more secure.
- Some plugins or scripts require a minimum version.
- Very old versions may no longer receive security updates.
Step-by-step: change your PHP version #
- Log in to DirectAdmin (usually yourdomain.com:2222).
- Go to Account Manager and click Select PHP Version (sometimes under “PHP Selector” or “Domain Setup”).
- Choose the domain if you have more than one.
- Select the PHP version you want from the dropdown.
- Click Save or Set as current.
Enabling PHP extensions #
After choosing a version you can often enable extra modules:
- Look for a list of extensions on the same page.
- Tick the ones your application needs (for example, mbstring or curl).
- Save your changes.
Checking the active version #
- Create a PHP info page, or
- In WordPress, go to Tools > Site Health > Info > Server to see the PHP version.
Troubleshooting #
- Site breaks after switching: revert to the previous version, then update your software before trying again.
- A plugin needs an extension: enable it in the PHP settings.
- Change not applied: clear any caching and reload.
Recommended approach #
- Back up your site first.
- Move up one version at a time if you are on something very old.
- Test key pages and forms after each change.
