Display or Change the PHP Version

The scripting language PHP is the engine that drives many great dynamic websites and web applications. WordPress, Joomla! and eCommerce platforms like Magento or PrestaShop use PHP.

This is how you determine the current configuration and set the desired PHP version for each of your domains:

Please note: Changing the PHP version may affect the functionality of your application or scripts. If you do not write your own applications, we recommend that you check the manufacturer's specifications beforehand. In case of a problem, you can switch back to the previous PHP version at any time.

  • Log in to My 1&1 IONOS and open the PHP settings.
  • You will now see an overview of your domains. In the column PHP version you can read the active PHP version.
  • If you want to change a domain or subdomain to another version of PHP, click on the domain you want to edit.
  • Select the PHP version you want.
    Hint: A current PHP version offers higher speed and new features. PHP 7, for example, speeds up many dynamic websites by over 100% compared to PHP 5.6 with OpCode caching and an optimized Zend engine.
  • Click on Save.

The new PHP version is now activated. This may take a moment.

Did you know that you can also move multiple domains in one step. Simply check the desired domains in the overview and then click on Select PHP version.
