Need Help With Displaying Info

This is a multiplication test for students to take and when they finish they click the score button. after they click the score button it tells them what their score is, with the opportunity to take it again.

 

What I am trying to do is make this able to keep the recent score and just post the next score. Right now my app just gives the first score and then when I take the test again it just refreshes and gives the new score. I want it to play the new score under the old score. I can't seem to figure out how to do this. If someone could help point me in the right direction. Would appreciate the help.

 

 

Here is my code for my app....

 

 

 

<?php

	require_once('database.php');






define ('ROWS', 3);
define ('COLS', 3);
define ('MAX_NUMBER', 12);
date_default_timezone_set('America/New_York');



if (isset($_POST['btn_score']))
{

	$result_name= $_POST['result_name'];

	$correct = 0;


	//print_r ($_POST);
	$time1 = $_POST['ts'];
	$time1_object = new DateTime($time1);
	$now = new DateTime();
	$time_span = $now->diff($time1_object);

	$minutes = $time_span->format('%i');
	$seconds = $time_span->format('%s');
	$seconds+= $minutes * 60;

	echo "It took $seconds seconds to complete the test<hr />";



	foreach ($_POST as $problem => $answer)
	{
		if ($problem <> "btn_score" && $problem <> "ts" && $problem <> "result_name")
		{
			//echo "$problem -- $answer <br />";
			$problem = explode('_', $problem);
			$num1 = $problem[2];
			$num2 = $problem[3];



			$right = $num1 * $num2;


			if ($answer != $right)
			{
			echo "$num1 * $num2 = $answer , The right answer is $right<br />";
			}else 
			{
				$correct = $correct + 1;

			}




			}
	}
	$result_score= 0;
	$result_score= ($correct / 9) * 100;

	echo "your score is <br/>$result_score<br/>";

}


$sql = "INSERT INTO results (result_name, result_score, result_date_time) VALUES ('$result_name','$result_score', NOW());";










?>

once you have the old score, add it to a session which can be called later when needed.
