The latter asks "Is this key in the array?" whereas isset() adds "and is its value not null?" While isset() is every-so-slightly faster, this should not be a concern. Use whichever makes sense for the context here.

Hi David,

	Thank you for the explanation.  It's nice to know the difference between them.  Since they are equivalent for my use, I went with array_key_exists, simply because it makes more sense to me in English. ;)

	Thanks again to everyone.  I got it to work _and_ there are no more errors!!!
