php - Searching Multi-Dimension Array With Multiple Results -


let's have array , want search value should return multiple results:

array(2) {   [0] => array(2) {     ["id"] => string(2) "1"     ["custom"] => string(1) "2"     }   [1] => array(2) {     ["id"] => string(2) "2"     ["custom"] => string(1) "5"     }   [2] => array(2) {     ["id"] => string(2) "3"     ["custom"] => string(1) "2"     } }

i want search key custom value = 2, following result:

array(2) {   [0] => array(2) {     ["id"] => string(2) "1"     ["custom"] => string(1) "2"     }   [1] => array(2) {     ["id"] => string(2) "3"     ["custom"] => string(1) "2"     } }

is possible without looping through array? there such class or built in function this?

the array_filter function want.

$array = [     [         'id' => '1',         'custom' => '2'     ],     [         'id' => '2',         'custom' => '5'     ],     [         'id' => '3',         'custom' => '2'     ] ];  $customs = array_filter(     $array,     function ($arr) {         return is_array($arr) && array_key_exists('custom', $arr) && $arr['custom'] === '2';     } );
