计算营业天数我需要一个在PHP中添加“业务天数”的方法。例如,周五12/5+3个工作日=周三12/10。至少,我需要这些代码来理解周末,但理想情况下,它也应该考虑到美国联邦假日。如果有必要的话,我相信我可以用暴力来解决问题,但我希望有一种更优雅的方法。有人吗?谢谢。

<?php//The function returns the no. of business days between two dates and it skips the holidaysfunction getWorkingDays($startDate,$endDate,$holidays){ // do strtotime calculations just once $endDate = strtotime($endDate); $startDate = strtotime($startDate); //The total number of days between the two dates. We compute the no. of seconds and divide it to 60*60*24 //We add one to inlude both dates in the interval. $days = ($endDate - $startDate) / 86400 + 1; $no_full_weeks = floor($days / 7); $no_remaining_days = fmod($days, 7); //It will return 1 if it's Monday,.. ,7 for Sunday $the_first_day_of_week = date("N", $startDate); $the_last_day_of_week = date("N", $endDate); //---->The two can be equal in leap years when february has 29 days, the equal sign is added here //In the first case the whole interval is within a week, in the second case the interval falls in two weeks. if ($the_first_day_of_week <= $the_last_day_of_week) { if ($the_first_day_of_week <= 6 && 6 <= $the_last_day_of_week) $no_remaining_days--; if ($the_first_day_of_week <= 7 && 7 <= $the_last_day_of_week) $no_remaining_days--; } else { // (edit by Tokes to fix an edge case where the start day was a Sunday // and the end day was NOT a Saturday) // the day of the week for start is later than the day of the week for end if ($the_first_day_of_week == 7) { // if the start date is a Sunday, then we definitely subtract 1 day $no_remaining_days--; if ($the_last_day_of_week == 6) { // if the end date is a Saturday, then we subtract another day $no_remaining_days--; } } else { // the start date was a Saturday (or earlier), and the end date was (Mon..Fri) // so we skip an entire weekend and subtract 2 days $no_remaining_days -= 2; } } //The no. of business days is: (number of weeks between the two dates) * (5 working days) + the remainder //---->february in none leap years gave a remainder of 0 but still calculated weekends between first and last day, this is one way to fix it $workingDays = $no_full_weeks * 5; if ($no_remaining_days > 0 ) { $workingDays += $no_remaining_days; } //We subtract the holidays foreach($holidays as $holiday){ $time_stamp=strtotime($holiday); //If the holiday doesn't fall in weekend if ($startDate <= $time_stamp && $time_stamp <= $endDate && date("N",$time_stamp) != 6 && date("N",$time_stamp) != 7) $workingDays--; } return $workingDays;}//Example:$holidays=array("2008-12-25","2008-12-26","2009-01-01"); echo getWorkingDays("2008-12-22","2009-01-02",$holidays)// => will return 7?>

使用示例:
echo number_of_working_days('2013-12-23', '2013-12-29');
产出:
3
职能:
function number_of_working_days($from, $to) { $workingDays = [1, 2, 3, 4, 5]; # date format = N (1 = Monday, ...) $holidayDays = ['*-12-25', '*-01-01', '2013-12-23']; # variable and fixed holidays $from = new DateTime($from); $to = new DateTime($to); $to->modify('+1 day'); $interval = new DateInterval('P1D'); $periods = new DatePeriod($from, $interval, $to); $days = 0; foreach ($periods as $period) { if (!in_array($period->format('N'), $workingDays)) continue; if (in_array($period->format('Y-m-d'), $holidayDays)) continue; if (in_array($period->format('*-m-d'), $holidayDays)) continue; $days++; } return $days;}
