Assuming you would have the first array and the second like this:

$firstArray = ['a' => 3, 'b' => 9];
$secondArray = ['c' => 7, 'd' => 1];

PHP allows you to concatenate the results by using the plus symbol +:

$test = $firstArray + $secondArray;
//$test = [
//    'a' => 3,
//    'b' => 9,
//    'c' => 7,
//    'd' => 1,
//];

And after that, to sort by values:

asort($test);
//$test = [
//    'd' => 1,
//    'a' => 3,
//    'c' => 7,
//    'b' => 9,
//];
