只使用while循环一次遍历结果

知道为什么这只循环一次吗?我试图有嵌套面板从DB的每个结果。我知道这里可能有很多不好的做法，但我只是需要它为一门课工作。这永远不会投入生产。

while($row = mysql_fetch_array($result)) {
    echo sizeof($row);
    $resId=$row[reservationId];
    $counter++;
    try {
        $startDate = new DateTime($row[startDate]);
    } catch (Exception $e) {
        echo $e->getMessage();
        exit(1);
    }
    try {
        $endDate = new DateTime($row[endDate]);
    } catch (Exception $e) {
        echo $e->getMessage();
        exit(1);
    }
    echo "
