All Google Cloud based accounts may change their PHP versions for each of their sites individually. You can choose between PHP 5.6, PHP 7, and PHP 7.1. We highly recommend at least PHP 7 as it is much faster, resource-friendly, and more secure than its predecessors.
Change WordPress PHP Version
To change the WordPress PHP version you’ll need to take the following steps:
- Log in to your My Kinsta dashboard
- Go to Sites and select the site you’d like to change the PHP version on
- Go to the Tools tab and find the PHP Engine section
- From the dropdown select your preferred PHP version
Then click on the “Switch” button to confirm your choice.
This process may take up to 3 minutes. At the end of the process your PHP engine will be restarted which may result in a a couple of seconds of downtime for your WordPress backend only, your site visitors will not experience any downtime. While the PHP version is being changed you can navigate away from the above page but some actions like cache management will be unavailable until the new engine has been activated. You will receive a notification in the dashboard as soon as the change has been made.
