[arch-general] Installing php 7 and php56 at the same time?

[David C. Rankin]

All,

  I need to downgrade php from 7 to 5.6. I built the 5.6.19 package from AUR and
I'm now at the install stage. Before I do I thought I would ask if I need to
remove php7 before installing php5.6? The PKGBUILD has no 'conflicts' or
'replaces' specified and they are prefixed differently (e.g. php and php56), but
what I am unclear on is how my applications will know which one to use?

  This was necessitate when php7 broke part of my groupware package
(webdav/caldav/carddav) that I need working until those can be upgraded.

  Do I just install php56 along side php7 or remove php7 first?

If removed, then I set IgnorePkg in packman.conf
