MultiPHP Manager is a powerful tool within cPanel that allows you to manage PHP versions across your domains. It is particularly useful for environments not using CloudLinux OS, or for add-on domains and sub-domains that need to run a different PHP version.

In your cPanel control panel you can manage the PHP settings for your website, including the PHP version, PHP extensions, and custom PHP variables like memory_limit and max_input_vars.
Many known PHP settings can be managed via the cPanel control panel on the "Select PHP Version" page, without the need to manually create a php.ini configuration file.

Step-by-Step Guide:

1. Navigate to MultiPHP Manager:

   • Find and click on the "MultiPHP Manager" icon under the "Software" section:
     
     
     
     

2. Select the Domain:

   • You will see a list of your domains. Select the checkbox next to the domain(s) for which you want to change the PHP version.

3. Choose the PHP Version:

   • From the drop-down menu at the top right corner labeled "PHP Version", select the desired PHP version.
   • If you select "inherit" as the PHP version, the default PHP version mentioned under "System PHP Version" will apply.
     • Please Note: If you have selected a different PHP version under the "Select PHP Version" page, that version will apply instead for all domains that have "inherit" selected.

4. Apply the PHP Version:

   • Click the "Apply" button to set the chosen PHP version for the selected domain(s):
     
     
     
     

5. Recommended: Repair the MySQL Database:

   • Different PHP versions work in conjunction with different MySQL database drivers. If your website is displaying a 404 error or content is missing, please repair the MySQL database.
   • Repairing the database will only take a moment, does not require advanced technical knowledge, and should normally not harm your website in any way.

6. Verify the Changes:

   • It’s a good practice to verify the PHP version change by trying to access your website.
   • If you notice any errors, such as "500 Internal Server Error", please refer to this guide: Troubleshooting a broken website after switching PHP version
   • You can create a phpinfo.php file temporarily containing <?php phpinfo(); ?> in the root directory of your domain and access it via your web browser. This will display the current PHP version and configuration details.
   • If you encounter any issues, please revert back to the old PHP version and settings. Should the issue persist, please contact our support team for assistance.

Additional Tips:

1. Check for Underlying Issues: If database corruption is a recurring problem, investigate the root cause, such as a PHP extension mismatch, resource usage overuse, software conflicts, faulty updates, or server-related issues.

2. Consider Professional Assistance: If you are uncomfortable performing database repairs or if issues persist, consider seeking assistance from your developer, a professional database administrator or our technical support team.
