Install php 7.3 / 7.4 to Debian Stretch

Hi all,

I've two servers running on Debian Stretch with PHP 7.0 and PHP 7.2 enabled, and I followed these tutorials for these:

https://www.howtoforge.com/tutorial...-9-stretch-apache-bind-dovecot-ispconfig-3-1/

and this one:

https://www.howtoforge.com/tutorial/how-to-install-php-7-on-debian/

That all works great but I want to install support for PHP 7.3 and PHP 7.4 - can I use this tutorial to make this work:

https://www.howtoforge.com/tutorial...fig-3-from-debian-packages-on-debian-8-and-9/

It looks pretty straight forward but I wonder if I need to start from the very beginning - step 2 - to add a new version for the installed PHP version.

Is this the correct way to start or is there another working solution.

Thanks in advance for your reply,

Cheers,

Arie
