I'm working on an ongoing project that depends on a shared webserver running
an old version of PHP (4.1.2 I believe). Is there any good reason to stick
with an older version of PHP, or might it be a valid suggestion to have it
upgraded to something a bit more recent? I have a notion that upgrade
attempts may have been snubbed out by the way things like register_globals
are now handled by default, the perception being that newer versions of PHP
are incompatible with older code.
the register globals "event" happened on 4.1 (from memory), so any install over that should be straight forward. in any case, it's just one simple directive that needs to be changed in the php.ini file... can't see how this should be an issue.
i think the best reason to keep up-to-date on the versions is that each new release is "better, more stable, etc etc"... i haven't ever heard anyone on this list say "i prefer 4.2.3 over 4.2.4" :)
as a programmer, i hate it how some hosts refuse to keep on top of the upgrades... really useful functions in newer versions aren't available.
Mainly I'm concerned that code I test on our in-house server running
version-current PHP will depend on function calls and language constructs
that the production server's vintage PHP interpreter lacks.
exactly... there isn't a HUGE number of differences between the current release and what they've got on the live server, but there are exceptions... i was making good use of file_get_contents() on my LAN, but had to write a user-function to replicate it when running on the live server which is stuck at 4.2.3 for the moment.
it's almost a case of "don't upgrade your LAN until the production server upgrades", but I prefer "convince you host to upgrade, or move host" :)
