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

on the local host i have PHP Version 5.4.4-14+deb7u5

on the remote server i have PHP Version 5.2.6

the error i get is

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

It's called array dereferencing, and was introduced in PHP 5.4 — Mark Baker

I'm not sure why nobody has mentioned this yet, but this is called array dereferencing and was introduced in PHP 5.4. See Example #7. — Pekka

@Pekka웃 There's something about dereferencing in one of the answers now. Perhaps that'll help. — user1864610

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>";
?>
