note 43861 deleted from function.array-key-exists by jome

Note Submitter: lordfarquaad at notredomaine dot net ---- This function is equivalent to <? isset($array[$key]); ?> The only difference seems to be in the warning messages: if you use an incorrect $key (= not a string or a number), isset would give you a "Illegal offset type" warning (in fact it is the passed expression that would generate it) and array_key_exists would say "array_key_exists(): The first argument should be either a string or an integer"...
