php - 计算每 2 行的时间戳之间的时间

Question

我有下表，正如您在表中看到的，用户对每个休息都有一个“休息”和“休息”条目，但我正在努力计算每次休息所花费的时间。 你们能帮忙吗？ 谢谢。

ID  Name      Action     Datetime
 2  John Doe  BREAK OUT  2018-05-24 09:00:41
 3  John Doe  BREAK IN   2018-05-24 09:10:45
 4  John Doe  BREAK OUT  2018-05-24 13:00:49
 5  John Doe  BREAK IN   2018-05-24 13:30:52
 6  John Doe  BREAK OUT  2018-05-24 15:30:56
 7  John Doe  BREAK IN   2018-05-24 15:40:59

Answer 1

好吧，由于您没有真正说明如何获取这些数据以及您想在哪里显示结果，因此您可以通过以下方式获得您想要的结果:

function getDateDiff($breakOut, $breakIn) {
    $dateStart = new DateTime($breakOut);
    $dateEnd   = new DateTime($breakIn); 

    $dateDiff  = $dateStart->diff($dateEnd); 

    return $dateDiff->format("%H:%I:%S");
}

现在您只需使用该函数并返回 diff :

2   John Doe    BREAK OUT   2018-05-24 09:00:41
3   John Doe    BREAK IN    2018-05-24 09:10:45

var_dump(getDateDiff("2018-05-24 09:00:41", "2018-05-24 09:10:45")); // '00:10:04'

4   John Doe    BREAK OUT   2018-05-24 13:00:49
5   John Doe    BREAK IN    2018-05-24 13:30:52

var_dump(getDateDiff("2018-05-24 13:00:49", "2018-05-24 13:30:52")); // '00:30:03'

6   John Doe    BREAK OUT   2018-05-24 15:30:56
7   John Doe    BREAK IN    2018-05-24 15:40:59

var_dump(getDateDiff("2018-05-24 15:30:56", "2018-05-24 15:40:59")); // '00:10:03'

因此，如果您想在 PHP 循环中获得这些结果，也许您可​​以尝试以下操作:

// your data array, I assume it looks like this since I have no info
$array(
    2 => array(
        "name" => "John Doe",
        "break" => "2018-05-24 09:00:41",
    ),
    3 => array(
        "name" => "John Doe",
        "break" => "2018-05-24 09:10:45",
    ),
    4 => array(
        "name" => "John Doe",
        "break" => "2018-05-24 13:00:49",
    ),
    5 => array(
        "name" => "John Doe",
        "break" => "2018-05-24 13:30:52",
    ),
    ...
); 

$array_break_time = array();
foreach ($array as $key => $data) {
    if ($key % 2 == 0) {
        if(isset($array[$key + 1])) {
            $array_break_time[] = getDateDiff($data["break"], $array[$key + 1]["break"])
        }
    }
}

输出是:

$array_break_time = array(
    0 => '00:10:04',
    1 => '00:30:03'
    ....
);

但是由于我没有更多详细信息，因此不知道它是否适合您的情况!
