[FX.php List] Very strange session variable problem

[DC]

Just a late follow up to this thread...

I just debugged a similar problem and I didn't have the luxury of moving 
to another server! ;-)

There seems to be a variable scoping "problem" (or just a difference) in 
PHP 4.3.10 where SESSION variables that once had their own scope overlap 
with local variables (and probably globals though i didn't test it).

i'll bet that this original issue described by Bob P. was a variable 
collision and the change from one version of PHP to the other resolved 
the problem because the SESSION variables got re-scoped properly.

just writin' what i've seen and worked through - no searching the PHP 
bug database...
