Question

我想计算出勤表中的小时数但是我不想计算不是这两次之间的小时和分钟：08：00到14:00

例如：员工A在09:00到达工作，在16:00离开结果应该是5个小时如果员工B在8:30到达工作岗位并在14:00离开结果应该是5小时30分钟

亲切的问候

Answer 1

您可以使用Datetime对象来执行此操作。有文档：http://php.net/manual/en/datetime.diff.php

<?php
$datetime1 = new DateTime('2009-10-11');
$datetime2 = new DateTime('2009-10-13');
$interval = $datetime1->diff($datetime2);
echo $interval->format('%R%a days');
?>

Answer 2

这是你的答案

<?php
$restriction_start = strtotime("30-Mar-2015 08:00:00");
$restriction_end = strtotime("30-Mar-2015 14:00:00");

$start_time = strtotime("30-Mar-2015 09:00:00");
$end_time = strtotime("30-Mar-2015 16:00:00");


echo calculateTime($start_time, $end_time, $restriction_start, $restriction_end);


function calculateTime($start_time, $end_time, $restriction_start, $restriction_end)
{
    $start = $restriction_start;
    if($start_time>$restriction_start)
    {
        $start = $start_time;
    }

    $end = $restriction_end;
    if($end_time<$restriction_end)
    {
        $end = $end_time;
    }

    $time_diff = $end-$start;

    $output = gmdate("H:i:s", $time_diff);

    return $output;
}
?>

Answer 3

var $NbrSec = mktime($hour1, $minute1, $second1, $month1, $day1, $year1)
               - mktime($hour2, $minute2, $second2, $month2, $day2, $year2);

var $Hr = ((int)($NbrSec / 60)) * 60;
var $Mn = $NbrSec % 60;

echo $Hr . ":" . $Mn;

如何在两个固定时间之间计算两次？
