Answer 1

您可以让SQL查询为您排序。假设该列是Date格式。如果没有，请查看：SQL ORDER BY date problem。

在查询中进行排序后，您只需将其转换为时间，然后根据需要格式化日期。这可能会给你你想要的东西：

<?

$datetime = strtotime($row->createdate);
$mysqldate = date("m/d/y g:i A", $datetime);

$result = mysqli_query($con,"SELECT Date FROM pallettracker GROUP BY Date");

foreach($result as $date){
    $datetime = strtotime($result);
    $date = date("M d, y", $datetime);
    echo $date . '/';
}

?>

我不明白，为什么在不使用分组功能时使用GROUP BY。更好的方法是DISTINCT

我会以这种方式更新你的代码：

$result = mysqli_query($con,"SELECT DISTINCT `Date` FROM `pallettracker` ORDER BY `Date` DESC");
while($date = mysqli_fetch_assoc($result)
{
    echo date('',strtotime($date['Date'])).'<br />';
}

重要的是，mysql中的“Date”col的格式为Date或Datetime
