Actually I read an article a couple of mos. ago where someone shared their
experience installing two versions on their box - 4 as the base (default)
install and 5 as the supplementary version. It was done as Apache modules.
The default was installed as any PHP version might be done, and 5 was
installed in the same $prefix but in the php5 directory - as opposed to the
php directory. This permitted the use of php version; by extension, per
directory, and/or by the use of .htaccess. Many others followed his article
and attempted to do it themselves. But reported failure. Turns out that the
one thing all failed attempts had in common was their OS (Linux). Linux
has a less efficient/flexible loading mechanism than *BSD(i). Which (as
you noted) causes symbol collision. The article was quite old, so I was
unable to get the beginnings of it. So perhaps Linux has since made some
provisions that overcome this problem (newer kernels). Anyway, I was hoping
that some with a similar (working) experience might share it here. As I'm
sure that ability would lend itself to generating an increased interest in
installing 5 (or 6) along with their base 4 install. It would also shorten
any attempt on my part to do the same. :)

Thanks for taking the time to respond.

P.S. Please don't top post. It buggers up the threads and breaks context.
