PHP: 时间段，早上和晚上分别是多少时间？

Question

假设我有两个字符串，例如“08:50”（开始）和“23:50”（结束）。现在我知道早上是从 06:00 到 22:00，晚上是从 22:00 到 06:00。

问题是，我怎么知道早上几点钟，晚上几点钟？早上应该是9小时，晚上应该是1小时50分钟。

我做了一个代码，但有时（具有特定值）它会崩溃，并且会损失几分钟：

function analizza_mattina_sera($result2) 
{
    $inizio_giorno = oreToMinuti("06:00");
    $fine_giorno = oreToMinuti("22:00");
    $inizio_notte = oreToMinuti("22:00");
    $fine_notte = oreToMinuti("06:00");
    $conto_minuti_giorno = "";
    $conto_minuti_notte = "";

    while ($row2 = mysql_fetch_array($result2)) {

        $data1 = strtotime($row2["anno"] 
            ."-". $row2["mese"]
            ."-". $row2["giorno"]
            ." ". $row2["ora_effettiva"]);

        $data2 = strtotime($row2["anno"]
            ."-". $row2["mese"]
            ."-". $row2["giorno"]
            ." ". $row2["ora_teorica"]);

        $differenza = (($data2 - $data1) / 3600) / (1 / 60);

        if ($row2["verso"] == "entrata") {
            $ora_usa = $row2["ora_effettiva"];
            if (oreToMinuti($ora_usa) < $inizio_giorno) {
                $conto_minuti_notte = $fine_notte - oreToMinuti($ora_usa);
            }
            if (oreToMinuti($ora_usa) > $inizio_giorno) {
                $conto_minuti_giorno = oreToMinuti($ora_usa) - $inizio_giorno;
            }
        }
        else {
            $ora_usa = $row2["ora_effettiva"];
            if (oreToMinuti($ora_usa) < $fine_giorno) {
                if (oreToMinuti($ora_usa) < $fine_notte) {
                    $conto_minuti_notte = ($fine_notte - oreToMinuti($ora_usa)) - $conto_minuti_notte;
                }
                else {
                    $conto_minuti_giorno = oreToMinuti($ora_usa) - $inizio_giorno - $conto_minuti_giorno;
                }
            }
            else {
                $conto_minuti_notte = oreToMinuti($ora_usa) - $inizio_notte;
                $conto_minuti_giorno = $fine_giorno - $conto_minuti_giorno - $inizio_giorno;
            }
        }
    }

    return str_replace("-", "", ($conto_minuti_giorno == "" ? 0 : $conto_minuti_giorno)
        ."_". ($conto_minuti_notte == "" ? 0 : $conto_minuti_notte)) ."<br />";
}

Answer 1

我希望这是你要找的..我已经转换为小时..

举个例子

Start - 4.30 and End - 21.30 then morning 15.5 hours and night 1.5 hours
Start - 4.30 and End - 22.30 then morning 16 hours and night 2 hours
Start - 6.30 and End - 21.30 then morning 15 hours and night 0 hours
Start - 6.30 and End - 22.30 then morning 15.5 hours and night 0.5 hours

以下脚本可能对您有所帮助。

        <?php
    //Get the timeslote how many hours spent in the morning and how many hours spent in the night
    $start = "00:00";
    $end = "00:00";
    $morningSlote = "06:00 - 22:00";
    $nightSlote = "22:00 - 06:00";
    $startTime = strtotime($start);
    $endTime = strtotime($end);
    $startDate = date("m/d/Y");
    $endDate = date("m/d/Y");
    if($startTime > $endTime) {
        //Date will be changed
        //i.e. 11.30 PM - 2.30 AM
        //i.e. 11.30 PM - 6.20 PM
        $startDate = date("m/d/Y H:i:s",strtotime($start));
        $endDate = date("m/d/Y H:i:s",strtotime("+1 day".$end));

你可以试试这个（你应该添加一些验证）。

这里是如何使用它，它会return一个以分钟为单位的早晨时段和以分钟为单位的夜间时段的数组：

categorizePeriod('08:50', '23:50');

函数如下：

function minutesDiff($startTime, $endTime)
{
    $isNextDay = ($startTime > $endTime) ? 1 : 0;
    $start = explode(':', $startTime);
    $end = explode(':', $endTime);
    $diffInSeconds = abs(mktime($start[0], $start[1], 0, null, date('j'), null) - mktime($end[0], $end[1], 0, null, date('j') + $isNextDay, null));

    return floor($diffInSeconds/60);
}

function inMorning($time, array $morning)
{
    return ($morning[0] <= $time && $time <= $morning[1]);
}

function categorizePeriod($startTime, $endTime, array $morning = array('06:00', '22:00'))
{
    if ($startTime == $endTime) {
        return array(0, 0);
    } else if ($startTime > $endTime) {
        $beforeMidnight = categorizePeriod($startTime, '23:59', $morning);
        $afterMidnight = categorizePeriod('00:00', $endTime, $morning);

        return array(
                $beforeMidnight[0] + $afterMidnight[0] + (int)inMorning('00:00', $morning),
                $beforeMidnight[1] + $afterMidnight[1] + (int)!inMorning('00:00', $morning),
        );
    }

    if (inMorning($startTime, $morning) && inMorning($endTime, $morning)) {
        return array(
                minutesDiff($startTime, $endTime),
                0
        );
    } elseif (!inMorning($startTime, $morning) && !inMorning($endTime, $morning)) {
        return array(
                0,
                minutesDiff($startTime, $endTime)
        );
    } elseif (inMorning($startTime, $morning) && !inMorning($endTime, $morning)) {
        return array(
                minutesDiff($startTime, $morning[1]),
                minutesDiff($morning[1], $endTime)
        );
    } elseif (!inMorning($startTime, $morning) && inMorning($endTime, $morning)) {
        return array(
                minutesDiff($morning[0], $endTime),
                minutesDiff($startTime, $morning[0])
        );
    }
}

PHP: 时间段，早上和晚上分别是多少时间？

PHP: Time slot, how much time on morning and on night?
