1. Log into your DA account
2. Navigate to Account Manager >> Domain Setup
3. Select the domain you want to change the PHP version for.
4. On the right side click on the PHP Version Selector link and select the desired PHP version from the list.

To check the PHP version your site is using you can create a file phpversion.php with the following content and open it in your web browser:
<?php
// prints e.g. 'Current PHP version: 8.0.1'
echo 'Current PHP version: ' . phpversion() . '<br/>';
?>
