For a long time, I believed it was Virtualmin's fault that I couldn't choose to have multiple versions of PHP to choose from for virtual servers. That finally managed, eventually, to go through my thick skull, that this was actually Debian's fault, that as a principle, the distro only allows to run with one fixed PHP, thus making maintaining it simple, preventing errors and ensuring maximum security.
That said, it IS still possible, with DotDeb. Or with methods such as https://erdfisch.de/en/multiple-versions-php-apache-under-linux
And so: do you think it would be possible for Virtualmin to assist us Debian users in having several versions of PHP, both 5 and 7? Taking us by the hand, simply asking "choose which php secondary version to add: 5.5, 5.6, 5.7, 7?", and automagically doing all the work after this. (Context, if that matters: I'd love to switch to php7 some day, but a few websites I host are definitely php7-incompatible, so I'm stuck with PHP5 unless I can have multiple versions simultaneously.)
I fully realize am I asking too much here, and that, by all means, it should NOT be Virtualmin's responsibility to help with something that may make a system less stable or less secure. But, hey: maybe I'm mistaken, and it is simpler than it looks, and not risky! Operative expression being "just in case". I'm asking, just in case :)
Good day everyone!
