Hi,
isset($array[$key]) is around 160% faster than array_key_exists($key, $array).
That's one of the changes we've benchmarked in Doctrine 1 that we
integrated into Doctrine 1.2.
Of course there're some situations that you cannot trust isset() and
you should still keep with array_key_exists.
Cheers,
