1&1 PHP Extended Support

PHP 4, 5.2, 5.4 and 5.5 no longer receive support from the PHP community. For those who want to continue using older versions of PHP, 1&1 Extended Support offers interruption-free operation until you switch to a current PHP version.

Why is Extended Support Necessary?

Security checks, adjustments and operation of old PHP versions create a great deal of work for our administrators. PHP Extended Support is a special service we offer our customer base. Because maintaining the old PHP versions increases the administrative workload on our systems, we charge you a small monthly fee for this additional service.

Because we assume that you still need your PHP 4, 5.2, 5.4 or 5.5 scripts, we have already activated this enhancement for your contract. It ensures that your PHP scripts will remain functional in the future and we have also sent you more detailed information on this subject by e-mail.

When does 1&1 Extended Support Begin?

1&1 Extended Support starts immediately after support by the PHP community ends. The first 6 months of 1&1 Extended Support are free of charge for you. You will find further information of the various PHP support phases and the entire PHP lifecycle on the 1&1 Community website.

Regardless, we recommend that you always use the current PHP version if possible.

Check to See If You Need PHP Extended Support:
  • For testing we recommend you set up a subdomain.
  • Now link the page content to the subdomain.
  • Afterwards, you can switch to PHP 7 (recommended).

If everything works the way you want it to, you can cancel PHP Extended Support with just a few clicks using the contract service.

Why Am I Already Being Charged for PHP Extended Support?
  • You are still using PHP version 4, 5.2, 5.4 or 5.5 for one of your domains or websites. If you want to change this setting for each domain, please go back to your 1&1 Control Panel and change PHP version. We recommend that you always use a current PHP version like PHP 7.
  • It is possible that after switching your website or domain to a current PHP version, PHP Extended Support was not cancelled from your package. If you no longer need our Extended Support service, log in to our contract page and select cancellation of individual items to cancel it.
  • You did not receive information about our PHP Extended Support by e-mail in advance. Log into your Control Panel and make sure the correct e-mail address is connected to your account.
My Scripts No Longer Work After Changing Versions

Simply switch back to the original PHP version in the 1&1 Control Panel if you encounter issues after switching

I Need More Time to Adjust My Scripts for a Newer PHP Version

Please test first whether an adjustment of the scripts is necessary. Many scripts run smoothly even under PHP5.6. If this is not the case for you, and you need to make greater adjustments, please contact our customer support to coordinate the timing.
