Well, the second call returns false because 'key' does not appear as a
value in the associative array. (Only as a key.) It also returns false
for values of 2, 3, etc.

I have no idea why the first call returns true, though... If you pass
true as the third parameter ("strict") to in_array, it will return false
as expected.
