Trivia Quiz

[webtoon]

I want to be able to load random questions into a Flash 5 movie like this http://www.webtoonist.com/triviaquiz/triviaquiz.swf using PHP/MySQL, can anyone tell me how I might do this, please?
Thanks!

$q = mysql_query("SELECT id FROM trivia",$conn_id);
$counter =0;
while($foo = mysql_fetch_row($q)) {
$idArray[$counter] = $foo[0];
$counter++;
}

$currentQid = $idArray[rand(0,count($idArray))];
