Personally I keep using PHP 4 and do not see the motivation

First because, for me, PHP 4 is already a feature complete
language for
Web development. Second, because I do not have the time nor
the patience
to chase all the backward incompatibilities of PHP 5 that
will break the
code of my sites.
Actually I am even scared to try PHP 5 in sites that I have
with large
code bases because it is very hard to fully test them in development
environment.
It is not impossible to test a large site in development
environment to
find the possible problems, but it would take a lot of time and still
many details could escape, so I am not interested to risk and
put a site
up malfunctioning due to PHP 5 incompatibilities, especially
when PHP 4
worked so well for all these years.
Last time this was debated here I pointed out that the upgrade from 4.x to
5.x will most certainly be less painful than upgrading from 4.x to 6.x (or
7.x, or 8.x) would be. That, in itself, is motivation to upgrade. Another
is that as time goes on and more people make the migration, fewer people
will be available to support 4.x.
Last time this was debated, someone posted instructions on how to have BOTH
versions on your server so that you can switch back and forth.
all good points IMHO, the 'someone' was Rasmus Lerdorf btw - worth remembering :-)
