why $count when you already have $number

function display_result($module_no, $max = null)
{
	if (is_string($module_no) && $module_no)
		$module_no = unserialize($module_no); // god knows why your using this
	if (!is_array($module_no)) return;

	if (!$max || !is_int($max)) $max = count($module_no);

	$count = 0;
	foreach ($module_no as $number => $data) {
		if ($count > $max) break;
		echo "Q.", $count++,' - <strong>',$data,'</strong><br />';
	}
}


PS - generally is better when function don't echo stuff... it makes them
more flexible.
