mai chris_upjohn :: utc #. there are a lot of user comments in the php docs that can help you with questions such as this, see the below link. php.net/manual/en/function.arraysearch.php#  i have two comments. first, what is the purpose of $current_key ? since you're not changing it, just use $key . second, by your usage, i'd say that foreach ($haystack as $key => $item) if ($item["md"] === $needle) return $key; return false;. is quite enough. of course, if the above was just an example and you really want to  déc. <?php checks that the $news array has a key 'results' $this>array($news)>haskey('results'); or checks that the $news array has a 'results' key containing an array which has items in it $this>in($news) >array['results']>hassize(). in the last example, you can replace the >array['results'] by  checks if multiple keys exist in an array. . param array $array. param array|string $keys. . return bool. function array_keys_exist( array $array, $keys ) {. $count = ;. if ( ! is_array( $keys ) ) {. $keys = func_get_args();. array_shift( $keys );. } foreach ( $keys as $key ) {. if ( isset( $array[$key] )
