我需要一种在PHP中添加“工作日”的方法。例如，星期五12/5 + 3个工作日= 12月12日星期三。
至少我需要代码来理解周末，但理想情况下它也应该考虑到美国联邦假期。我敢肯定，如果有必要，我可以通过蛮力提出解决方案，但我希望那里有更优雅的方法。任何人吗？
感谢。

这是PHP手册中date（）函数页面上user comments的函数。这是评论中早期功能的改进，增加了对闰年的支持。
输入开始日期和结束日期，以及可能介于两者之间的任何假期数组，并以整数形式返回工作日：
<?php
//The function returns the no. of business days between two dates and it skips the holidays
function 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--;
}
return $workingDays;

//Example:

date()函数有一些应该有用的参数。如果你检查日期（“w”）它会给你一个星期几的数字，从星期日的0到星期六的6。所以..也许就像..
$busDays = 3;
$day = date("w");
if( $day > 2 && $day <= 5 ) { /* if between Wed and Fri */
$day += 2; /* add 2 more days for weekend */
}
$day += $busDays;
这只是一种可能性的粗略例子..

以下是将商务天添加到日期的功能
function add_business_days($startdate,$buisnessdays,$holidays,$dateformat){
$i=1;
$dayx = strtotime($startdate);
while($i < $buisnessdays){
$day = date('N',$dayx);
$date = date('Y-m-d',$dayx);
if($day < 6 && !in_array($date,$holidays))$i++;
$dayx = strtotime($date.' +1 day');
}
return date($dateformat,$dayx);
}
//Example
date_default_timezone_set('Europe\London');
$startdate = '2012-01-08';
$holidays=array("2012-01-10");
echo '<p>Start date: '.date('r',strtotime( $startdate));
echo '<p>'.add_business_days($startdate,7,$holidays,'r');
另一篇文章提到了getWorkingDays（来自php.net的评论并包含在这里），但我认为如果你从一个星期天开始并在一个工作日结束就会中断。
使用以下内容（您需要包含上一篇文章中的getWorkingDays函数）
date_default_timezone_set('Europe\London');
//Example:
$holidays = array('2012-01-10');
$startDate = '2012-01-08';
$endDate = '2012-01-13';
echo getWorkingDays( $startDate,$endDate,$holidays);
结果为5而不是4
Sun, 08 Jan 2012 00:00:00 +0000 weekend
Mon, 09 Jan 2012 00:00:00 +0000
Tue, 10 Jan 2012 00:00:00 +0000 holiday
Wed, 11 Jan 2012 00:00:00 +0000
Thu, 12 Jan 2012 00:00:00 +0000
Fri, 13 Jan 2012 00:00:00 +0000
以下函数用于生成上述内容。
function get_working_days($startDate,$endDate,$holidays){
$debug = true;
$work = 0;
$nowork = 0;
$dayx = strtotime($startDate);
$endx = strtotime($endDate);
if($debug){

我的版本基于@mcgrailm的工作...因为报告需要在3个工作日内进行审核，如果在周末提交，计数将在下周一开始：
function business_days_add($start_date, $business_days, $holidays = array()) {
$current_date = strtotime($start_date);
$business_days = intval($business_days); // Decrement does not work on strings
while ($business_days > 0) {
if (date('N', $current_date) < 6 && !in_array(date('Y-m-d', $current_date), $holidays)) {
$business_days--;
}
if ($business_days > 0) {
$current_date = strtotime('+1 day', $current_date);
}
}
return $current_date;
}
根据工作日计算两个日期的差异：
function business_days_diff($start_date, $end_date, $holidays = array()) {
$business_days = 0;
$current_date = strtotime($start_date);
$end_date = strtotime($end_date);
while ($current_date <= $end_date) {
if (date('N', $current_date) < 6 && !in_array(date('Y-m-d', $current_date), $holidays)) {
$business_days++;
}
if ($current_date <= $end_date) {
$current_date = strtotime('+1 day', $current_date);
}
}
return $business_days;
}
作为一个注释，每个使用86400或24 * 60 * 60的人请不要......你的遗忘时间从冬季/夏季时间变化，其中一天不是24小时。虽然它比strtotime（'+ 1天'，$ timestamp）慢一点，但它更可靠。

* Requires PHP 5.1 (Using ISO-8601 week)
*/

if($timestamp === false) $timestamp = time();
while ($bDays>0) {
$timestamp += 86400;
if (date('N', $timestamp)<6) $bDays--;
}
return $timestamp;
}
变式2：
<?php
/*
* Does not count current day, the date returned is a business day
* following the last business day
* Requires PHP 5.1 (Using ISO-8601 week)
*/
function businessDays($timestamp = false, $bDays = 2) {
if($timestamp === false) $timestamp = time();
while ($bDays+1>0) {
$timestamp += 86400;
if (date('N', $timestamp)<6) $bDays--;
}
return $timestamp;
}
变式3：
<?php
/*
* Does not count current day, the date returned is
* a date following the last business day (can be weekend or not.
* See above for alternatives)
* Requires PHP 5.1 (Using ISO-8601 week)
*/
function businessDays($timestamp = false, $bDays = 2) {
if($timestamp === false) $timestamp = time();
while ($bDays>0) {
$timestamp += 86400;
if (date('N', $timestamp)<6) $bDays--;
}
return $timestamp += 86400;
}
通过执行以下操作，可以使用上述变体进行额外的假期考虑。注意！确保所有时间戳都是一天的同一时间（即午夜）。
制作一系列假日日期（作为unixtimestamps），即：
$holidays = array_flip(strtotime('2011-01-01'),strtotime('2011-12-25'));
修改行：
if (date('N', $timestamp)<6) $bDays--;
是：
if (date('N', $timestamp)<6 && !isset($holidays[$timestamp])) $bDays--;
完成！

这是另一种解决方案，它比使用in_array检查假期快了近25％：

* @param array(string) $holidayDates -- OPTIONAL. Array of holidays dates, formatted as Y-m-d. (e.g. array("2016-08-15", "2016-12-25"))
* @return int -- Number of working days.
*/
function getWorkingDays($startDate, $endDate, $holidayDates=array()){
$dateRange = new DatePeriod(new DateTime($startDate), new DateInterval('P1D'), (new DateTime($endDate))->modify("+1day"));
foreach ($dateRange as $dr) { if($dr->format("N")<6){$workingDays[]=$dr->format("Y-m-d");} }
return count(array_diff($workingDays, $holidayDates));

我有同样的需要，我开始使用bobbin的第一个例子，最后得到了这个
function add_business_days($startdate,$buisnessdays,$holidays=array(),$dateformat){
$enddate = strtotime($startdate);
$day = date('N',$enddate);
while($buisnessdays > 1){
$enddate = strtotime(date('Y-m-d',$enddate).' +1 day');
$day = date('N',$enddate);
if($day < 6 && !in_array($enddate,$holidays))$buisnessdays--;
}
return date($dateformat,$enddate);

计算两个日期之间的工作日，包括假期和自定义工作周
答案不是那么简单 - 因此我的建议是使用一个类，你可以配置更多依赖于简单化的功能（或假设一个固定的语言环境和文化）。要在一定数量的工作日之后获得日期，您需要：
功能方法
/**
* @param days, int
* @param $format, string: dateformat (if format defined OTHERWISE int: timestamp)
* @param start, int: timestamp (mktime) default: time() //now
* @param $wk, bit[]: flags for each workday (0=SUN, 6=SAT) 1=workday, 0=day off
* @param $holiday, string[]: list of dates, YYYY-MM-DD, MM-DD
*/
function working_days($days, $format='', $start=null, $week=[0,1,1,1,1,1,0], $holiday=[])
{
if(is_null($start)) $start = time();
if($days <= 0) return $start;
if(count($week) != 7) trigger_error('workweek must contain bit-flags for 7 days');
if(array_sum($week) == 0) trigger_error('workweek must contain at least one workday');
$wd = date('w', $start);//0=sun, 6=sat
$time = $start;
while($days)
{
if(
$week[$wd]
&& !in_array(date('Y-m-d', $time), $holiday)
&& !in_array(date('m-d', $time), $holiday)
) --$days; //decrement on workdays
$wd = date('w', $time += 86400); //add one day in seconds
}
$time -= 86400;//include today
return $format ? date($format, $time): $time;
}
//simple usage
$ten_days = working_days(10, 'D F d Y');
echo '<br>ten workingdays (MON-FRI) disregarding holidays: ',$ten_days;
//work on saturdays and add new years day as holiday
$ten_days = working_days(10, 'D F d Y', null, [0,1,1,1,1,1,1], ['01-01']);
echo '<br>ten workingdays (MON-SAT) disregarding holidays: ',$ten_days;

对于假期，以date（）可以生成的某种格式制作一系列日期。例如：
// I know, these aren't holidays
$holidays = array(
'Jan 2',
'Feb 3',
'Mar 5',
'Apr 7',
// ...
);
然后使用in_array()和date()函数检查时间戳是否代表假期：
$day_of_year = date('M j', $timestamp);
$is_holiday = in_array($day_of_year, $holidays);

尽管在撰写本文时，这个问题有超过35个答案，但是有一个更好的解决方案。
@flamingLogos提供了一个基于数学的答案，不包含任何循环。该解决方案的时间复杂度为Θ(1)。但是，其背后的数学运算非常复杂，尤其是the年的处理。
@Glavić提供了一个极好的，优雅的解决方案。但是它不能在固定的时间内进行计算，因此，如果以10天或100年之类的大周期使用，则它可能会产生拒绝服务（DOS）攻击或至少超时，因为它以1天为间隔循环。 >
因此，我提出了一种数学方法，该方法具有固定的时间并且非常易读。
这个想法是计算整整几周的天数。
<?php
function getWorkingHours($start_date, $end_date) {
// validate input
if(!validateDate($start_date) || !validateDate($end_date)) return ['error' => 'Invalid Date'];
if($end_date < $start_date) return ['error' => 'End date must be greater than or equal Start date'];
//We save timezone and switch to UTC to prevent issues
$old_timezone = date_default_timezone_get();
date_default_timezone_set("UTC");
$startDate = strtotime($start_date);
$endDate = strtotime($end_date);
//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 include both dates in the interval.
$days = ($endDate - $startDate) / 86400 + 1;
$no_full_weeks = ceil($days / 7);
//we get only missing days count to complete full weeks
//we take modulo 7 in case it was already full weeks
$no_of_missing_days = (7 - ($days % 7)) % 7;
$workingDays = $no_full_weeks * 5;
//Next we remove the working days we added, this loop will have max of 6 iterations.
for ($i = 1; $i <= $no_of_missing_days; $i++){
if(date('N', $endDate + $i * 86400) < 6) $workingDays--;
}
$holidays = getHolidays(date('Y', $startDate), date('Y', $endDate));
//We subtract the holidays
foreach($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)
$workingDays--;
}
date_default_timezone_set($old_timezone);
return ['days' => $workingDays];
}
该函数的输入采用php中的Y-m-d格式或常规日期格式的yyyy-mm-dd格式。

如果您需要获取两个日期之间有多少时间，可以使用https://github.com/maximnara/business-days-counter。
它很简单，但现在仅适用于laravel $diffInSeconds = $this->datesCounter->getDifferenceInSeconds(Carbon::create(2019, 1, 1), Carbon::now(), DateCounter::COUNTRY_FR);
它不计算公众假期和周末，您可以设置工作间隔，例如从9到18，有启动时间或没有发布时间。
或者如果您只需要周末并且使用Carbon，则可以使用内置功能：
$date1 = Carbon::create(2019, 1, 1)->endOfDay();
$date2 = $dt->copy()->startOfDay();
$diff = $date1->diffFiltered(CarbonInterval::minute(), function(Carbon $date) {
return !$date->isWeekend();
}, $date2, true);
但是它将每隔一分钟间隔一次，对于位间隔可能需要一段时间。

我刚刚创建了这个函数，它似乎运行得很好：
function getBusinessDays($date1, $date2){
if(!is_numeric($date1)){
$date1 = strtotime($date1);
}
if(!is_numeric($date2)){
$date2 = strtotime($date2);
}
if($date2 < $date1){
$temp_date = $date1;
$date1 = $date2;
$date2 = $temp_date;
unset($temp_date);
}
$diff = $date2 - $date1;
$days_diff = intval($diff / (3600 * 24));
$current_day_of_week = intval(date("N", $date1));
$business_days = 0;
for($i = 1; $i <= $days_diff; $i++){
if(!in_array($current_day_of_week, array("Sunday" => 1, "Saturday" => 7))){
$business_days++;
}
$current_day_of_week++;
if($current_day_of_week > 7){
$current_day_of_week = 1;
}
}
return $business_days;
}
echo "Business days: " . getBusinessDays("8/15/2014", "8/8/2014");

就个人而言，我认为这是一个更清洁，更简洁的解决方案：
function onlyWorkDays( $d ) {
$holidays = array('2013-12-25','2013-12-31','2014-01-01','2014-01-20','2014-02-17','2014-05-26','2014-07-04','2014-09-01','2014-10-13','2014-11-11','2014-11-27','2014-12-25','2014-12-31');
while (in_array($d->format("Y-m-d"), $holidays)) { // HOLIDAYS
$d->sub(new DateInterval("P1D"));
}
if ($d->format("w") == 6) { // SATURDAY
$d->sub(new DateInterval("P1D"));
}
if ($d->format("w") == 0) { // SUNDAY
$d->sub(new DateInterval("P2D"));
}
return $d;
}
只需将建议的new日期发送到此功能。

感谢Bobbin，mcgrailm，Tony，James Pasta和其他一些发布在这里的人。我编写了自己的函数来将日期添加到工作日，但是使用我在此处找到的一些代码对其进行了修改。这将处理周末/假日的开始日期。这也将处理营业时间。我添加了一些注释并分解代码以便于阅读。
<?php
function count_business_days($date, $days, $holidays) {
$date = strtotime($date);
for ($i = 1; $i <= intval($days); $i++) { //Loops each day count
//First, find the next available weekday because this might be a weekend/holiday
while (date('N', $date) >= 6 || in_array(date('Y-m-d', $date), $holidays)){
$date = strtotime(date('Y-m-d',$date).' +1 day');
}
//Now that we know we have a business day, add 1 day to it
$date = strtotime(date('Y-m-d',$date).' +1 day');
//If this day that was previously added falls on a weekend/holiday, then find the next business day
while (date('N', $date) >= 6 || in_array(date('Y-m-d', $date), $holidays)){
$date = strtotime(date('Y-m-d',$date).' +1 day');
}
}
return date('Y-m-d', $date);
}
//Also add in the code from Tony and James Pasta to handle holidays...

$bankHolidays = array(
'New Years Day' => $year . "-01-01",
'Martin Luther King Jr Birthday' => "". date("Y-m-d",strtotime("third Monday of January " . $year) ),
'Washingtons Birthday' => "". date("Y-m-d",strtotime("third Monday of February " . $year) ),
'Memorial Day' => "". date("Y-m-d",strtotime("last Monday of May " . $year) ),

return $bankHolidays;
}
//Now to call it... since we're working with business days, we should
//also be working with business hours so check if it's after 5 PM
//and go to the next day if necessary.

if (date(G) >= 17) {
$start_date = date("Y-m-d", strtotime("+ 1 day")); //Tomorrow

add_business_days有一个小bug。使用现有功能尝试以下操作，输出将是星期六。
Startdate =星期五 要添加的工作日= 1 假期数组=添加下一个星期一的日期。
我在下面的函数中修正过。
function add_business_days($startdate, $buisnessdays, $holidays = array(), $dateformat = 'Y-m-d'){
$i= 1;
$dayx= strtotime($startdate);
$buisnessdays= ceil($buisnessdays);
while($i < $buisnessdays)
{
$day= date('N',$dayx);
$date= date('Y-m-d',$dayx);
if($day < 6 && !in_array($date,$holidays))
$i++;
$dayx= strtotime($date.' +1 day');
}
## If the calculated day falls on a weekend or is a holiday, then add days to the next business day
$day= date('N',$dayx);
$date= date('Y-m-d',$dayx);
while($day >= 6 || in_array($date,$holidays))
{
$dayx= strtotime($date.' +1 day');
$day= date('N',$dayx);
$date= date('Y-m-d',$dayx);
}
return date($dateformat, $dayx);}

$day = date('N',$enddate);
while($buisnessdays > 0){ // compatible with 1 businessday if I'll need it
$enddate = strtotime(date('Y-m-d',$enddate).' +1 day');
$day = date('N',$enddate);
if($day < 6 && !in_array(date('Y-m-d',$enddate),$holidays))$buisnessdays--;
}
return date($dateformat,$enddate);
}

https://github.com/Arbitr108/useful_php这是一个可以估算日历工作日的课程。因此，估算后只需将日历期添加到您需要的日期
答案 36 :(得分：-1)
有一个公式：
number_of_days - math_round_down(10 * (number_of_days / (business_days_in_a_week * days_in_a_week)))
多田！你可以用你想要的任何方式计算一个月，一个星期，一天中的工作日数。
math_round_down（）是一种假设的方法，它实现了向下舍入的数学函数。
