    How to split correct and incorrect answers for certain option types

    Code below seperate correct letters and incorrect letters from each other if option type is letter. E.g If option type is A-D and correct letter is B, then it removes B from A B C D using the `$wrong` variable making it A C D for `$incorrect_ans` variable.

    Now what I want to do is that if option type is `Yes or No` and correct answer is `Yes`, then it should seperate `Yes` from `Yes, No` so that I can display `No` in `incorrect_ans` variable. Problem is that at the moment it is not spilt both these options, so it is displaying bother this answers as incorrect answers when in this example `No` should be incorrect. But how can this be achieved?

    I want the same to work for `True or False` option as well. As I mentioned my code works for letter answers, just not `Yes or No` or `True or False`.

    Below is code:
    PHP Code:
       $specialOptionTypes = array('Yes or No' => array( 'Yes''No' ),'True or False' => array( 'True''False' ));
        while (
    $stmt->fetch()) {
    // Do this for each row:
    if ( array_key_exists$dbOptionType$specialOptionTypes ) ) {
    $options $specialOptionTypes[$dbOptionType];
        } else if ( 
    preg_match'/^([A-Z])-([A-Z])$/'$dbOptionType$match ) ) {
    $options range$match[1], $match[2] );
        } else {
    // issue warning about unrecognized option type
    $options = array();
    $right $dbAnswer// $right = 'True';
    $wrong array_diff$options$right );  
    $incorrect_ans[] = $wrong;

    my question would be... why? But whatever.

    What type does $dbAnswer have?
    Never grow up. The instant you do, you lose all ability to imagine great things, for fear of reality crashing in.
