如果发生sql错误，

mysql_query可以返回布尔值false 

    if($result === false) {
        var_dump(mysql_error());
    }
    else {
        if (mysqli_num_rows($result) > 0) {
            if (mysqli_num_rows($result) > 0) {
                while ($row = mysqli_fetch_assoc($result)) {
                    echo "<tr>";
                    echo "<td>$row[soalan1]</td>";
                    echo "<td>$row[soalan2]</td>";
                    echo "<td>$row[soalan3]</td>";
                    echo "<td>$row[soalan4]</td>";
                    echo "<td>$row[soalan5]</td>";
                    echo "<td>$row[soalan6]</td>";
                    echo "<td>$row[soalan7]</td>";
                    echo "<td>$row[nota]</td>";
                    echo "</tr>";
                }
            } else {
                echo "0 results";
            }
        }
    }

您也可以更改行

if (mysqli_num_rows($result) > 0) {

为：

if ($result !== false && mysqli_num_rows($result) > 0) {

但是你需要var_dump mysql错误才能看到你的查询出了什么问题
