$_SESSION variable only stores one value

I have this code:

// Values of drop-down lists (cmbPosition)
$studPosition = array();
$i = 0;
foreach ($_SESSION['arrayNamePosition'] as $value) {
    $studPosition[$i] = $_GET[$value];
    $i++;
// Calculates the points for each student in the event
    $points = ($_SESSION['noStudents']+1) - $_GET[$value]; 
    echo $points;
    $_SESSION['points'] = $points;
}

The code above loops through $_SESSION['arrayNamePosition'] which contains an array. Every thing works but $_SESSION['points'] = $points; is where the problem is (This is the $_SESSION variable which contains $points).

When I echo $points in the current php form, it outputs: 583276

But when I echo $_SESSION['points'] inside a while loop in a different php form it only outputs the last element stored in $echo $_SESSION['points']points which is 6.

How can I fix this so that echo $_SESSION['points'] outputs all the values of $points in a different php form.

NOTE: I have also put echo $_SESSION['points'] inside a for loop but it still outputs the last value stored in $points. e.g. output: 666666

Thanks in advance.

I guess you mean that the loop with echo $points; outputs you 583276. Like the $_SESSION['points'], it stores only one value, but you print the value each time. I would suggest following changes:

$studPosition = array();
$i = 0;
$points = '';
foreach ($_SESSION['arrayNamePosition'] as $value) {
  $studPosition[$i] = $_GET[$value];
  $i++;
  $points = $points.(($_SESSION['noStudents']+1) - $_GET[$value]); 
}
echo $points;
$_SESSION['points'] = $points;

Variable points is not an array, therefore it contains only last calculated element. Change it to array, then save each value as new element in array.

It's because $_SESSION['points'] itself is not an array. You should change your line to:

$_SESSION['points'][] = $points;
