PHP How to get the intersection of two or more arrays -


i trying intersection of 2 or more arrays kind of structure:

first array:

array(     [0] => array(         ['room_id'] => 21         ['room_name'] => 'gb 101'         ['capacity'] => 40     )     [1] => array(         ['room_id'] => 22         ['room_name'] => 'h 114'         ['capacity'] => 20     )     [2] => array(         ['room_id'] => 23         ['room_name'] => 'gb 203'         ['capacity'] => 20     )     [3] => array(         ['room_id'] => 25         ['room_name'] => 'h 100'         ['capacity'] => 30     )     [4] => array(         ['room_id'] => 26         ['room_name'] => 'gb 206'         ['capacity'] => 40     ) )

second array:

array(     [0] => array(         ['room_id'] => 21         ['room_name'] => 'gb 101'         ['capacity'] => 40     )     [1] => array(         ['room_id'] => 23         ['room_name'] => 'gb 203'         ['capacity'] => 20     )     [2] => array(         ['room_id'] => 26         ['room_name'] => 'gb 206'         ['capacity'] => 40     ) )

resulting array:

array(     [0] => array(         ['room_id'] => 21         ['room_name'] => 'gb 101'         ['capacity'] => 40     )     [1] => array(         ['room_id'] => 23         ['room_name'] => 'gb 203'         ['capacity'] => 20     )     [2] => array(         ['room_id'] => 26         ['room_name'] => 'gb 206'         ['capacity'] => 40     ) )

i tried using array_intersect_assoc intersection using following code:

$result = call_user_func_array('array_intersect_assoc', $arrays);

it trick gives following warning expected according here:

a php error encountered

severity: notice

message: array string conversion

i making ajax based system error messes up. there way intersection of arrays?

try serializing them:

$result = array_map('unserialize',               array_intersect(                   array_map('serialize', $first), array_map('serialize', $second)));
