I use symlinks for that. I have a symlink /usr/local/php-active which
points to e.g /usr/local/php-5.2.6 (the stable version) (php is compiled
with --prefix=/usr/local/php-5.2.6) /usr/local/bin/php is a symlink which
points to /usr/local/php-active/bin/php.  So I am sure if I call php
from the commandline that the right php version gets called.
For the apache module my makefile with which I compile php renames the
.so file to another name and I have another symlink libphpactive.so
which points to that lib.  So if I want to upgrade I compile a new php
version, test it from the command line and fpr apache I use a test
process which has the same docroot as the production server but uses the
newly build php lib. If all goes well I change two symlinks, restart
Apache and am finished.  If I saw later problems I could easily jump
back to an earlier version by changing these two symlinks.

(I compile php as DSO; if you compile PHP as statically bound Apache
module it's the same. Just put every Apache version in an own directory
and have a symlink which points to the version you want for production.)
