I am trying to display scores by what the user is requesting either 'Average','Total',or 'Both'. The following is my code for the looper.php and below is the code for my index.php.

This is my index.php page.....


if (isset($_POST['action'])) {
    $action =  $_POST['action'];
} else {
    $action =  'start_app';

switch ($action) {
    case 'start_app':
        $scores = array();
        $scores[0] = 70;
        $scores[1] = 80;
        $scores[2] = 90;
    case 'process_scores':
        $scores = $_POST['scores'];

        // validate the scores
        // TODO: Convert this if statement to a for loop
        if (empty($scores[0]) ||
            empty($scores[1]) ||
            empty($scores[2]) ||
            !is_numeric($scores[0]) ||
            !is_numeric($scores[1]) ||
            !is_numeric($scores[2])) {
                $scores_string = 'You must enter three valid numbers for scores.';

        // process the scores
        // TODO: Add code that calculates the score total
        $scores_string = '';
        foreach ($scores as $s) {
            $scores_string .= $s . '|';
        $scores_string = substr($scores_string, 0, strlen($scores_string)-1);

        // calculate the average
        $score_average = $score_total / count($scores);

        // format the total and average
        $score_total = number_format($score_total, 2);
        $score_average = number_format($score_average, 2);

    case 'process_rolls':
        $number_to_roll = $_POST['number_to_roll'];

        $total = 0;
        $count = 0;
        $max_rolls = -INF;

        // TODO: convert this while loop to a for loop
        while ($count < 1000) {
            $rolls = 1;
            while (mt_rand(1, 6) != 6) {
            $total += $rolls;
            $max_rolls = max($rolls, $max_rolls);
        $average_rolls = $total / $count;

include 'loop_tester.php';

I am kind of stuck as to what to do. I want to use a 'switch statement'. Would someone help me? Please?

Thank you for the nicely indented post. I am confused as to where you are stuck. Can you point out the exact line numbers and reason why you are stuck?
