    We have the latest ISPconfig 3.1 with PHP 7.2.5 on Ubuntu 18.04 installed. We would like to install an additional older PHP version 5.6 for customer website which required the older PHP version.

    I have seen this tutorial "How to install PHP 5.6 as additional PHP-FPM & FastCGI for ISPConfig 3.1 on Ubuntu 16.04"

    First - does this tutorial also work with Ubuntu 18.04? In that tutorial there are various options to configure PHP. When I did this I got config errors. To fix it I removed the options from configure, but not sure it was a good idea.

    Thanks - A tutorial for 18.04 would be perfect or a hint what change is necessary for 18.04 vs 16.10. I like the idea to have a lower version of PHP as addition in ISPconfig. The other option would be to configure a server with PHP 5.6.

    And we normally don't configure a server to lower version (php5.6), especially when default for Ubuntu 18.04 is php7.2.

    thanks for the commands - This means I would need to change default to php5.6 in order to use it. Right?

    No, do not change default PHP. ISPConfig most likely stops working if you do that.
    ISPConfig can handle multiple PHP versions per website, so you can use the PHP version you want for each website. But ISPConfig needs the PHP version that comes with the OS distribution.
