the error i get is

 Parse error: syntax error, unexpected '[' in /xxx/xxx/xxx/xxx/user/htdocs/quizzme.php on line 57

Answer 1

Array dereferencing is not supported on the earlier version of PHP. You need to do something like this:

<?php 
    $temp = $_SESSION['monster']->getQuestionNumber();
    echo "Num #  : " . $temp[$q] ."&nbspof&nbsp". $_SESSION['monster'] -> getTotalQuestions() . "<BR>";
?>
