Merge row data from a 2d array into the objects of an array related by an id and an object value within the row's range

I have an array:

$array1 = [
    (object)[
        'driver_id' => 2,
        'total' => 308,
        'total_driver' => 5,
        'score1' => 61.6000,
        'score2' => 62,
    ],
    (object)[
        'driver_id' => 3,
        'total' => 354,
        'total_driver' => 5,
        'score1' => 70.8000,
        'score2' => 71,
    ],
];

$array2 = [
    [
        'driver_id' => 2,
        'recommendation_min' => 0,
        'recommendation_max' => 50,
        'recommendation_key_range' => 'Low',
        'recommendation_observation' => 'Low',
        'recommendation_' => 'Low',
    ],
    [
        'driver_id' => 2,
        'recommendation_min' => 51,
        'recommendation_max' => 78,
        'recommendation_key_range' => 'Moderate',
        'recommendation_observation' => 'Moderate',
        'recommendation_' => 'Moderate',
    ],
];

How do I merge array to so that the driver_id 2 object looks like this:

[driver_id] => 2
[recommendation_min] => 51
[recommendation_max] => 78
[recommendation_key_range] => Moderate
[recommendation_observation] => Moderate
[recommendation_] => Moderate
[total] => 308
[total_driver] => 5
[score1] => 61.6000
[score2] => 62

A row should be merged with an object when it has the same driver_id and the score2 is between recommendation_min and recommendation_max.

Basically just need to use array_merge and a couple of predicate statements to decide which array to merge based on score1 & score2. Something like this should serve:

$drivers = array();
$drivers[0] = array('driver_id' => 2, 'total' => 308, 'total_driver' => 5, 'score1' => 61.6, 'score2' => 62 );
$drivers[1] = array('driver_id' => 3, 'total' => 354, 'total_driver' => 5, 'score1' => 70.8, 'score2' => 71 );

$recommends = array();
$recommends[0] = array('driver_id' => 2, 'recommendation_min' => 0, 'recommendation_max' => 50, 'recommendation_key_range' => "Low", 'recommendation_observation' => "Low", 'recommendation_' => "Low" );
$recommends[1] = array('driver_id' => 2, 'recommendation_min' => 51, 'recommendation_max' => 78, 'recommendation_key_range' => "Moderate", 'recommendation_observation' => "Moderate", 'recommendation_' => "Moderate" );

$results = array();
foreach($drivers as $driver) {
    if($driver['score1'] > 50 || $driver['score2'] > 50) {
        $driver = array_merge($driver,$recommends[1]);
    } else {
        $driver = array_merge($driver, $recommends[0]);
    }
    $results[] = $driver;
}
