PHP 7.4 support

I recently upgraded from a DietPi released based on Debian 10 to one that's based on Debian 11 (As the V10 release is losing all LTS in a couple of months) PHP in the process was upgraded from version 7.3 to 7.4.

I'm getting a lot of errors in my lighttpd error.log file; all related to PHP. I was wondering if this code has been tested verified on PHP7.4 as it's soon going to me the lowest supported version of PHP on the oldest supported distro.

I looked at /var/log/lighttpd/error.log and this thing is full of PHP errors. My microSD card with the stock image runs just fine, but on PHP 7.4, a lot of stuff is broken. For example, sending images to the NetDimm is stuck at 0%.
