What might be nice is a patch to PHP4 that provides a bit in error_reporting that would cause warnings on stuff that might break on a move to PHP5.

Someone could then switch it on and look at what is logged. I suspect that many people would also be pleasantly surprised that 4 -> 5 is not as hard as it seems.

I think this is a good idea but might be hard to implement.... thinking about it couldn't we do something along these lines in userspace? IOW create a script which parses php files and flags up possible issues?

Replying again:

the other thing is that this mode does not need to do everything, it needs to focus on the things that are hard to do by other means; eg:

1) warn on assignment of an object -- this is hard do to by 'eye balling' the
code.

2) be silent on the use of a user defined function with the name 'clone' The user can find this by the use of grep.

A list of things like (2) should be given and it made clear that (1) WILL NOT point them out.
