Question

我有两次$InTime：12:55:10而另一次是$OutTime：12:56:10

所以我认为计算时差应该是：

$TotalTimeInOffice = $OutTime - $InTime

我想要几个小时，所以我认为这应该是结果00:01，但我得到了错误的结果。通过这个计算，我在结果中得到0，但为什么？

以下是数据库中的一些示例：

InTime is: 12:55:10
OutTime is: 12:56:09
Result Is: 0
InTime is: 12:24:45
OutTime is: 00:00:00
Result Is: -12
InTime is: 10:05:48
OutTime is: 10:06:11
Result Is: 0

和PHP代码将是。

$timestart = $time_sheets->in_time;
$timestop = $time_sheets->out_time;
$time_diff = $timestop - $timestart ;
    echo "InTime is: $timestart <br />";
    echo "OutTime is: $timestop <br />";
    print_r('Result Is: '.$time_diff."<br />");

Answer 1

您的代码在涉及午夜时失败，例如12:24:45 - 00:00:00返回-12:24:45。如果它们位于午夜的任何一侧，则需要更正时间：

function getDuration($timestart, $timestop) {
    $time1 = new DateTime("today " . $timestart);
    $time2 = new DateTime("today " . $timestop);
    if ($time2 < $time1) {
        $time2 = new DateTime("tomorrow " . $timestop);
    }
    $time_diff = $time1->diff($time2);
    echo " InTime is: $timestart\n";
    echo "OutTime is: $timestop\n";
    echo " Result is: " . $time_diff->format("%r%H:%I:%S") . "\n\n";
}
getDuration("12:55:10", "12:56:09");
getDuration("12:24:45", "00:00:00");
getDuration("10:05:48", "10:06:11");
getDuration("11:00:00", "01:00:00");

输出：

 InTime is: 12:55:10
OutTime is: 12:56:09
 Result is: 00:00:59

 InTime is: 12:24:45
OutTime is: 00:00:00
 Result is: 11:35:15

 InTime is: 10:05:48
OutTime is: 10:06:11
 Result is: 00:00:23

 InTime is: 11:00:00
OutTime is: 01:00:00
 Result is: 14:00:00

Answer 2

我猜你应该使用strtotime（）将它转换为time（）; 然后使用$ timeOutTime - $ timeInTime;

   $timestart = $time_sheets->in_time;
    $timestop = $time_sheets->out_time;
    $timestart = strtotime($timestart);
    $timestop = strtotime($timestop);
    $time_diff = $timestop - $timestart ;
    echo data("h:i:s",$time_diff);

这应该有效。

// Change It
$time1 = new DateTime($timestart);
$time2 = new DateTime($timestop);
// $time_diff = $timestop - $timestart ;
$time_diff = $time1->diff($time2);
echo "InTime is: $timestart <br />";
echo "OutTime is: $timestop <br />";
print_r('Result Is: ' . $time_diff->format('%H:%I:%s') . "<br />");
// End of Change

使用DateTime函数解决问题，但如果还有其他好/更好的方法，那么请发布该答案..
