24小时的时间只显示12小时的时间

我正在处理我的PHP，因为我为我的脚本制作了24小时格式，包括年，月和日日期格式。但是，我的代码有点问题。

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的小时，它显示为中午12点，下午1点，下午2点等。当我有24个小时，我应该在早上12点有00，但我只能得到12个。

同样的事情是凌晨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）。

这是输出：

正如您在开始时间标记上看到的那样，例如：20140406183000。2014年是年份，04是月份，06是月份的日子，18是小时，30是分钟，00是秒。如果你查看时间，你会知道什么时间是正确的，什么时间是不正确的。你可以看到，我有一些时间没有设置正确。不正确的时间是早上12点（假设是00），凌晨1点（假设是01），凌晨2点（假设是02）等等。

您能告诉我解决问题需要做些什么吗？

1 个答案:

答案 0 :(得分：0)

这段代码很难阅读，但你有

的地方 
((int)($hours) + 12)

我会用这样的东西替换

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;
}

但我完全赞同这些评论者。试图自己解析日期/时间是一件痛苦而且不可靠的事情，这就是我们为这些语言使用函数的原因。

编辑：假设$time2的格式为h:mm a（例如5:30 PM），那么strtotime可用于转换为可靠的当前日期的格式（您在帖子中使用的格式）。

例如：

$start_time = strtotime($html_two->find('span[id=time1]',0)->plaintext);

然后，稍后...... 

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，如果你没有传递你对输入的期望，那么你将需要考虑它并且strtotime将返回false。
