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.
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.
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.
If everything works the way you want it to, you can cancel PHP Extended Support with just a few clicks using the contract service.
Simply switch back to the original PHP version in the 1&1 Control Panel if you encounter issues after switching
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.
