Adding Array of values to a multidimentional Array in PHP

I would like to add values from a $secondArray to $firstArray:

$firstArray = [
    0 => [
        'prodID' => 101,
        'enabled' => 1,
    ],
    1 => [
        'prodID' => 105,
        'enabled' => 0,
    ],
   ];

The $secondArray will always have the same amount of array items and will be in the same order as the $firstArray: 

$secondArray = [34, 99];

This is what I have tried but I keep getting the wrong stockQT values after the exercise:

foreach ($secondArray as $value) {
    foreach ($firstArray as &$firstArray) {
        $firstArray['stockQT'] = $value;
    }
}

Incorrect Result for a var_dump($firstArray):

array (size=2)
  0 => 
    array (size=3)
      'prodID' => int 101
      'subscribed' => int 1
      'stockQT' => int 99
  1 => 
    array (size=3)
      'prodID' => int 105
      'subscribed' => int 0
      'stockQT' => int 99

I have looked at similar posts but cant seem to get the correct vales after using different suggestions like while() loops. Below is what I need the $firstArray to look like:

array (size=2)
  0 => 
    array (size=3)
      'prodID' => int 101
      'subscribed' => int 1
      'stockQT' => int 34
  1 => 
    array (size=3)
      'prodID' => int 105
      'subscribed' => int 0
      'stockQT' => int 99

You just need one foreach() using the key since $secondArray will always have the same amount of array items and will be in the same order as the $firstArray. Notice the & to modify the actual value in the array:

foreach($firstArray as $key => &$value) {
    $value['stockQT'] = $secondArray[$key];
}

Or alternately loop $secondArray and use the key to modify $firstArray:

foreach($secondArray as $key => $value) {
    $firstArray[$key]['stockQT'] = $value;
}
