PHP 7.3 support to end soon
Time flies by. Here is yet another PHP version that will soon get no more security updates, so we will need to stop supporting it as well: PHP 7.3. Here is what our clients need to know about upcoming changes.
The final fore switch from PHP 7.3 to PHP 7.4 is now planned for 13th of April 2022. This will mark the end of the grace period. It will not be possible to switch back after that.
This is the simple way to update your App in 5 minutes. It should work for 90% of the Apps here:
- Make sure the software you are using is up-to-date
- In the fortrabbit Dashboard
- navigate to the App and then click on Settings > PHP
- Change to a newer PHP version and hit "save"
- Check if your website is still working after a few minutes
- You can safely switch back the version if it doesn't work (see below to continue)
If the above procedure is breaking your website or you don't want to risk your production environment, here is a better, more sophisticated way:
- Update your local development environment to at least
- Update the software you are using locally (think
- Push changes
- Change PHP version with our Dashboard (as described above)
Please see our old PHP upgrade path article; it was written for an older PHP version upgrade, but the steps are basically the same.
Please also see the official PHP 7.3 incompatible list.
We plan to force-update all Apps still running on
PHP 7.3 to
PHP 7.3 on the 21st of January 2022 (date is subject to change).
You will still be able to switch back your App to
PHP 7.3 with our Dashboard for an extended period of time after the first switch — this is what we consider the grace period. You can also ask us to exclude certain of your Apps (please include the App names) from the switch right away, so no switch will happen initially.
We plan to support the deprecated PHP version for one more month at least. The final switch off is planned to happen about a month later. We will announce that in our usual communication channels - status.fortrabbit.com.
For Apps in grace period, there will probably be no extra mailings. We reserve the right to do a force-update to PHP 7.4 at any time, in case serious security issues get revealed during the grace period. With the final switch, we will remove the PHP 7.3 binary so it will not be possible to switch back then any more.
Please reach out with questions and feedback. We are listening and happy to help.
Potentially asked questions
Which software version do I need to update to?
Sometimes it is difficult to find the time to upgrade an old project. Maybe you can get by with just a patch update? This is difficult to answer, projects rarely specify if their older releases support PHP 7.3, and there are plugins and custom code to consider.
To which PHP version shall I update?
Upgrade to PHP 7.4 if possible. The lowest version you need to update to now is
PHP 7.3, but since there are only minor differences between
PHP 7.3 and
PHP 7.4, it's likely that your App also runs on
PHP 7.4. So try the bigger jump right away.
Why do we need to do this?
Sorry, PHP deadlines are not set by us, see php.net. We cannot risk running unsupported PHP versions much longer for security reasons. See also the EOL document here.
Why can't we do the required updates for you?
It's your code, your website. You need to make sure that the project will run with a newer version of PHP. We cannot do that for you. We don't know your software and the inner workings of it. Check our support policies.
How can I test my code?
Please check out our old PHP testing article, highlighting strategies and tooling to test your code.
Thanks for taking the time to keep your software up-to-date. Have a question? Don't hesitate to ask us right away! We can also offer you a discount for running two versions of your Apps side by side.
