Re: Testing the existance of a value in an array

Benjamin,

Do you have the zend optimizer installed and if so did you upgrade it
the last time that you updated your php installation?  Also try
upgrading your php installation to the latest release and also
reinstalling your opimizer if you have one.

That may help.  I remember a while back I was having some big problems
with arrays not really working correctly and some extra data being
inserted into the array.
