获取日期时间格式之间的持续时间

使用DateTime类：

$start_date = new DateTime('2012-03-23 11:58:14');
$end_date = new DateTime('2012-03-24 11:54:29');
$dd = date_diff($end_date, $start_date);

要获得小时数，请使用$dd->h、分钟-$dd->i、秒-$dd->s。

echo "Hours = $dd->h, Minutes = $dd->i, Seconds = $dd->s";

我会

$start_time = strtotime($start_date);
$end_time = strtotime($end_date);
$difference = $end_time - $start_time;
echo date('H:i:s', $difference);

编辑

我在假设时差小于一天时犯了一个错误，所以如果时差大于一天，你只会看到小时：分钟：秒，这可能不是你想要的（如果忽略这个）

所以我现在会

$seconds = $difference % 60;            //seconds
$difference = floor($difference / 60);
$min = $difference % 60;              // min
$difference = floor($difference / 60);
$hours = $difference;  //hours
echo "$hours : $min : $seconds";

抱歉更正

这个函数会帮助你

function datediff($interval, $datefrom, $dateto, $using_timestamps = false) {
 /*
  $interval can be:
  yyyy - Number of full years
  q - Number of full quarters
  m - Number of full months
  y - Difference between day numbers
   (eg 1st Jan 2004 is "1", the first day. 2nd Feb 2003 is "33". The datediff is "-32".)
  d - Number of full days
  w - Number of full weekdays
  ww - Number of full weeks
  h - Number of full hours
  n - Number of full minutes
  s - Number of full seconds (default)
 */

1. 将这些字符串格式化为日期
2. 将这些日期转换为毫秒
3. 做日期 - 星日期
4. 根据结果计算 h：mm：ss。

在这里看到它的工作：http://codepad.viper-7.com/FPuOks

$start_date="2012-03-22 11:58:14";
$end_date="2012-03-24 11:54:29";
$start_time = strtotime($start_date);
$end_time = strtotime($end_date);
$difference = $end_time - $start_time;
echo sprintf("%02d%s%02d%s%02d", floor($difference/3600), ':', ($difference/60)%60, ':', $difference%60); // outputs 47:56:15
