80% of success is a normally formulated question))). Moreover, often when you formulate , you find the answer yourself)))
I will assume that from one array you need to get another, where the first subarray contains the keys, and the second contains the values. For example :

$testArray = ['1'=>'ОДЫН', '2'=>'ДЫВА' , '3'=>'ТРЫ',  '4'=>'ЧЯТЫРЯ' ];
$result =[];
foreach($testArray as $k=>$v){
    $result[0][] =  $k;
    $result[1][] =  $v;
 }

var_dump($result);
