Is there any tutorial on how to install php 7.4 using apt-get into debian 10? The one I got from google search is the following. Not sure if it is safe to use it. https://computingforgeeks.com/how-to-install-latest-php-on-debian/
It is not. ISPCOnfig on an operating system version only supports the default PHP version that comes with the OS. However, a website can be configured to use another PHP version, when there are additional PHP versions installed. Use this: https://www.howtoforge.com/tutorial...fig-3-from-debian-packages-on-debian-8-and-9/
Correct, and it's not just ISPConfig. All PHP applications that are installed via apt for that specific Debian version depend on the correct default PHP version, so other things like phpmyadmin, webmail, and others would fail as well. That's why one should never update the default version and always install older and newer PHP versions as additional PHP version.
All went well with the installation of php 7.4 Thank you @Taleman for the link and advice. Thank you @till for the advice.
