Assosiative array, assosiation names as first array index

I am trying to get the assosiation names of my array into the first index of the array without having to repeat the 50 "columns" Is that possibles. I was looking at
array_combine, array_merge, array_fill_keys.
But somehow that does seem to be the way I would want it. I can´t find the right function.

Array example:

loop some queryresult

    $array1 = array(
        "a" => $first,
        "b" => $second,
        "c" => $third
    }

Desired Output:

Array(
    [0] => Array(
        [a] => a,
        [b] => b,
        [c] => c
    ),
    [1] => Array(
        [a] => first,
        [b] => second,
        [c] => third
    ),

There's no way without iterating over the array keys.

$output = array(array(), $array1);
foreach(array_keys($array1) as $key)
    $output[0][$key] = $key;

It can be easily accomplished using array_keys() and array_combine():

$input = array(
    'a' => 'first',
    'b' => 'second',
    'c' => 'third',
);

$output = array(
    array_combine(array_keys($input), array_keys($input)),
    $input,
);
