It's simple. As I see it, there'll be no php4->php3 migration. That is
completely impractical; We've changed all of the core files, as well quite
a few modules, including source code, header files and directory structure.
 Right now, we have a php4 tree, which is php 3.0.6 based, and a ZendCore
tree that plugs in nicely to it. That php4 tree would be the base of the
php4 CVS; we'd have to migrate post-3.0.6 patches to it.
The point is very simple - don't invest time in restructuring the php3 tree
since you're going to dump it within a few days. Using it as a base for
php4 is simply an impractical waste of time.

About changing the API and directory structure at the same time, I'm not
sure if that was *the* problem of php 3.1 and the key to its lingering, I
happen to think that it didn't play a major role there. As long as we keep
the tree at a compilable state at all times, we can apply different kinds
of patches (structure and API) without significant problems. Another
difference from 3.1 is that I expect that php3 development would pretty
much slow to a halt once the php4 tree is available. It has definitely
been my recommendation all along, and still is.
