I my world where PHP is the glue between JSON requests and database queries, exists() would be a function I'd use way more the array_key_exists(), property_exists(), isset() and empty(). Further, in some scenarios exists($foo->bar) would replace isset($foo) && is_object($foo) && property_exists($foo, 'bar').
