Need to create descending order through loop

Question

I have two arrays. I am comparing those arrays through loop and calculating results but It is always making ascending order by the array indexes. I need to create order after calculation with those values in descending order.

<?php
$correctAnswers = [
['name'=> 1, 'value'=> 4],
['name'=> 1, 'value'=> 1]
];

$submittedStudentData =[
[101, 0, 1, 1],
[102, 0, 4, 1]
];

if(!is_array($submittedStudentData))
{
    $submittedStudentData = json_decode($submittedStudentData);
}


for ($index = 0; $index < count($submittedStudentData); $index++){

   // get each student data
   $studentData = $submittedStudentData[$index];

   // get the student roll number
   $studentId = $studentData[0];


   // initialize the total result with zero pre value
   $totalResult = 0;

// loop through the student's submitted answer
for ($i = 2; $i < count($studentData); $i++) 
{
   if ((int)$studentData[$i] === (int)$correctAnswers[$i - 2]["value"])
  {
    $totalResult++;
  }
}


// final result for this student
echo 'Student with roll number '. $studentId .' scores '. $totalResult."\n";


}
?>

The output is

Student with roll number 101 scores 1
Student with roll number 102 scores 2

I need the output by descending order with scores.

Student with roll number 102 scores 2
Student with roll number 101 scores 1
