Php 24小时时间仅显示12小时时间

我正在开发我的PHP，因为我正在为我的脚本制作一个24小时格式，包括年、月和日的日期格式。然而，我的代码有一个小问题

在我的代码中，它显示我有24小时的时间，我可以得到12、13、14、15、16、17、18、19、20、21、22和23的时间，它显示为中午12点、下午1点、下午2点……等等。当我有24小时，我应该有12点，但我只能得到12点

凌晨1点（小时显示为1）、凌晨2点（小时显示为2）、凌晨3点（小时显示为3）的情况也一样

以下是输出：

这段代码很难读懂，但您已经

((int)($hours) + 12)

我会用这样的东西来代替

getPaddedHour((int)$hours, $time9[1]);

并将函数定义为

function getPaddedHour($hour, $meridian) {
  $ret = $hour;
  if ($meridian == 'AM' && $ret == 12) { 
    $ret = 0;
  } else if ($meridian == 'PM' && $ret != 12) { 
    $ret += 11;
  }
  if ($ret < 10) {
    $ret = '0'.$ret;
  }
  return $ret;
}

然后，后来

if ($start_time !== FALSE) {
  $program_list[$count]['start_time1'] = date('YmdHis', $time);
} else {
  $program_list[$count]['start_time1'] = 'Not Available';
}

if/else语句是b/c如果您期望从输入中得到的信息没有传递，那么您需要对此进行说明，strotime将返回false。
Use DateTime（）当使用日期时，AW时间和日期操纵是一个糟糕的想法。你真的需要将其简化为一个更简明的示例，以便任何人都能提供帮助。@johncode和Dagon谢谢你的建议，你能告诉我为了获得24小时时钟，我需要做哪些更改吗？非常感谢，非常抱歉。我不认为我应该在哪里输入代码。看来我现在拿到了，我想我知道它在哪里了。我不知道应该在哪里输入代码。我想我找到了。所以我已经记下了你的答案。：）@Jeremey Miller对此非常感谢，那么我用什么正确的代码来替换
getPaddedHour（（int）$hours，$time9[1]）使用
$time1[0]=日期（“Ymd”）。（（整数）（$hours）+12）$分钟"00";？我明白，但你能给我一个你收到的实际数据的例子吗？然后我可以建议一个合适的替代方案。我如何才能为您提供我收到的实际数据的输出？在您对其进行任何更改之前，我需要将echo放入哪一行以获取输出？
$time1
。我需要将echo$time1放入哪一行？
if ($start_time !== FALSE) {
  $program_list[$count]['start_time1'] = date('YmdHis', $time);
} else {
  $program_list[$count]['start_time1'] = 'Not Available';
}
