Php fetch_array（）不保留查询的顺序

这是我的代码：

该表如下所示：

well_id     int(11)

well_name   varchar(50)

last_pull   datetime

hrs_to_fill datetime

它不像应该的那样按日期时间字段排序。在PHPMyadmin上运行查询工作正常，但此代码不是。。。有什么想法吗

谢谢

您的数据实际上是有序的；如果你仔细观察，你会发现每口井都是根据日期/时间排序的。原因是你有两个循环，内部循环运行三次，每口井一次

---

您可能需要在外循环之后移动内循环，以便在第一个循环中填充

临时井

表，并在第二个循环中查询它。

您可以发布正在查询的表的设计视图吗？要填写的hrs_的数据类型是什么？很可能您执行的代码与发布的代码不同。确保您执行的PHP文件是您想要的。另一个选项是浏览器缓存的页面。@LouieV，根据您的代码，每次运行insert后都会截断temp_wells表。你怎么会有不止一行呢？@Andy因为我需要计算$projected_datetime->insert to temp->fetch with order by的数据性质。同样在我截短之前，我正在进行提取，但没有提取订单如果

$company

是

O'Crockety's Bucket Co.

？不消毒不是为了防止攻击者，而是为了防止bug。对这件事马虎是没有理由的。对！对于每个

井

，

hrs\u-to\u-fill

（参见哈姆雷特和丹尼尔）我将一些代码从一个循环移动到另一个循环几次，最后混合了代码。无论如何，谢谢大家的意见

well_id     int(11)

well_name   varchar(50)

last_pull   datetime

hrs_to_fill datetime
