if anyone knows of some details info on how to keep multiple installs of php around (including apache modules) and being able to switch between them with minimal fuss then I be very happy to learn!

the easiest option is to use different prefix-paths for php default installation: ./configure --prefix=/usr/local some custom installation: ./configure --prefix=/opt/php53-test

I do this already, only the apache module, if compiled, is always installed where apxs2 says it should be put ... ergo it overwrites the version that I consider/use as default/production.

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.

is it safe to use a different make file? are there gotchas? care to share the make file (or the changes you make/made)? thanks anyway for your explaination .. It makes it very clear how I'll go about it from now on :-)

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.) Bye KP
