In cPanel's MultiPHP Manager, you can choose which PHP versions are available for users to select from in their account settings. If you want to disable certain alt-phpXX versions from the dropdown list, follow these steps:

1. Log in to WHM:

   Open your web browser and navigate to the WHM (Web Host Manager) dashboard.

2. Access MultiPHP Manager:

   In WHM, use the search bar or navigate to Home > Software > MultiPHP Manager.

3. Select PHP Versions:

   In the MultiPHP Manager, you'll see a list of available PHP versions. Locate the ones you want to disable.

4. Edit PHP Versions:

   To the right of each PHP version, there should be an "Edit" or "Edit PHP-FPM Settings" link. Click on it for the versions you want to disable.

5. Disable PHP Version:

   In the PHP Version Editor, uncheck the box next to "Allow users to select this PHP version" or a similar option that indicates user selection.

6. Save Changes:

   Scroll down and click on the "Save" or "Save PHP-FPM Settings" button.

7. Confirm Changes:

   You might need to confirm the changes you're making. Confirm that you want to disable the selected PHP version.

8. Repeat for Other Versions:

   Repeat the above steps for any other alt-phpXX versions you want to disable.

Keep in mind:

• Disabling PHP Versions means that users won't be able to select those versions for their websites. Existing websites using those PHP versions won't be affected, but new sites won't have the option.

• If you want to completely remove alt-phpXX versions from your server, you might need to do so from the command line or through package management, depending on your server's configuration.

Always ensure you have proper backups and a rollback plan in case any unintended issues arise from these changes. Additionally, consider communicating these changes to your users if they rely on specific PHP versions for their applications.
