Apart from what you described above, is it in general possible to force a
non-shell user to use a specific version of software when multiple
versions are installed on a machine, be it php, python or something else?
As I said, use the path. The path environment variable isn't part of a
shell, but shells provide nice ways to manipulate it. The scripts provided
with Software Collections modify the path and possibly other variables
before invoking a shell or a program. Environment variables are part of a
process' state and are inherited when a process spawns a child. A shell is
just a special kind of process that provides interactive support and may
provide a programming API.
