你可以试试这个代码。我是在早些时候遇到一个和你类似的问题时发现的。

if (isset($_GET['q1mrks']) && isset($_GET['marks']) && isset($_GET['qt1'])) {
$Q1mrks = $_GET['q1mrks'];
$marks = $_GET['marks'];
$qt1 = $_GET['qt1'];

$qtype_qry = mysql_query("
    SELECT *
    FROM s_questiontypes
    WHERE quetype_id = '$qt1'
");
$row = mysql_fetch_assoc($qtype_qry);
$qcode = $row['quetype_code'];

$sq_qry = "
    SELECT *
    FROM s_question
    WHERE quetype_code = '$qcode'
    ORDER BY RAND() LIMIT $Q1mrks
";
$sq_qry = mysql_query("
    SELECT *
    FROM s_question
    WHERE quetype_code = '$qcode'
    LIMIT $Q1mrks
");
while ($qrow = mysql_fetch_array($sq_qry)) {
    $qm = $qrow['marks'] . "<br />";
    $total += $qm . "<br />";
}
echo $total . "/" . $marks;
}
