I have the following code and what I need help with is changing the line marked below were I am dividing by 3, the size of the array , to be able to divide no matter what size the array. So I guess I am asking how to put that array into a variable to divide it.
Code: Select all
<html>
<?php
$student = array ( array (92,100,91),
array(96,82,77),
array(60,80,70),
array(90,90,90) );
$test_avg = array ();
foreach ($student as $name =>$identity){
$counter = 0;
foreach ($identity as $score){
$counter+=$score;
}
/**
* THIS LINE HERE IS THE ONE I AM TALKING ABOUT
*/
$test_avg [] = $counter / 3;
};
arsort($test_avg);
echo "<pre>";
echo 'Student Grade';
echo "<br/>";
foreach ($test_avg as $name => $test_avg){
printf ("%u %17s %.1f\n",$name, " ", $test_avg);
echo "<br/>";
};
echo "</pre>"
?>
