PHP How To Find the Keys of A Value In Multidimensional Array -


i have been working on problem, have had no result current functions of php.

i have multidimensional array, like:

array (     [3] => array         (             [16] => 0             [17] => 1             [18] => 2         )      [4] => array         (             [22] => 3             [23] => 4         )      [5] => array         (             [1] => 5         )  )

if first keys of array static, have been easy fix, keys dynamical data. (3, 4, 5 etc...). have function finds keys of value.

myfunction($myarray, 3) // 3 = value.

if there value "3", want function give me keys of it. (4, 22). array on top.

thanks in advance.

suppose want array of keys index of array contains searched value (3), , index of 3 value in array, should works:

$matched = []; foreach($object $extindex => $array){     foreach($array $intindex => $value){         if($value == 3){             $matched[] = [$extindex, $intindex];         }     } } var_dump($matched);

edit: $object object described in question.
