We would not use features that can't be emulated. With this technique we can have quicker and smaller code on PHP5 and still keep compatible with PHP4. We might need to talk to the guys who have written PEAR PHP Compat -- what they think of GPL'ing a part of that work? The problem is that some functions can be --easily-- emulated only in one way and I do not want to appear as if we stolen their code.

Unless we begin to use some advanced OOP mojo of PHP5 it's very likely that with the compatibility include and some PECL extensions D7 would still run on PHP4 -- just it would not be supported. I had some list here of what I want to use in PHP5 but I simply do not want this thread to divulge into that. Let's pretend we have an agreement that we know there are stuff exclusivel to PHP5 which we want.

I'm for the move. Most of my servers are running php5.x / mysql5.x
already, with the rest scheduled for migration before the end of the
year. I like seeing the older versions of php dropped. There is better
XML support in php5. I really would love to forget that expat exists at
all. SimpleXML makes it easier to consume and implement quite a few web
services.

is anyone aware of the support roadmaps in the RedHat camps?
