The problem with your script is that nobody has the time to look into
it to understand what is does. If you can't create a real simple
self-contained script which reproduces this bug, it's likely to be an
error in your script, and not in PHP.
I really think it's a bogus, you're using foreach multiple times which
is messy if you don't reset() at appropriate times.
Reopen if this is not the case.

1. Actually doing a "reset()" doesn't work at all.
2. I thought that this was a duplicate of #5052 - but now I see that
there's too different variables there for each level of the nested
"foreach()" - and I use the same variable.
So it seems that this is not a duplicate after all (corrent me if I'm
wrong).

It seems that this has been pointed out before... Sorry.
But this is still not solved (although the other bug reports about this
are already marked as "closed"). :(
I only saw a solution of using "reset()" in the end of the loop, but
this doesn't seem to be a good solution.
Any chances that each "foreach()" will be made to work on a new copy of
the array, so that nested "foreach()" will work?
