PHP에서 “영업일”을 추가하는 방법이 필요합니다. 예를 들어 금요일 12/5 + 영업일 3 일 = 수요일 12/10입니다.
최소한 주말을 이해하려면 코드가 필요하지만 이상적으로는 미국 연방 공휴일도 고려해야합니다. 필요한 경우 무차별 대입으로 해결책을 찾을 수 있다고 확신하지만 더 우아한 접근 방식이 있기를 바랍니다. 누군가?
감사.

다음 은 PHP 매뉴얼의 date () 함수 페이지에 대한 사용자 의견의 함수입니다. 윤년 지원을 추가하는 주석의 이전 기능을 개선 한 것입니다.
시작일과 종료일을 그 사이에있을 수있는 공휴일 배열과 함께 입력하면 작업 일이 정수로 반환됩니다.

두 날짜 사이에 휴일 이 없는 근무일 수를 가져옵니다 .
사용 예 :

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

도움이 될 date () 함수에 대한 몇 가지 인수가 있습니다 . 날짜 ( “w”)를 체크하면 일요일은 0부터 토요일은 6까지 요일에 대한 숫자가 표시됩니다. 그래서 .. 아마도 ..
$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;이것은 하나의 가능성에 대한 대략적인 예일뿐입니다 ..

휴일 계산은 각 주에서 비표준입니다. 어려운 비즈니스 규칙이 필요하지만 여전히 대략적인 표준 만 얻을 수있는 은행 신청서를 작성 중입니다.

날짜에 영업일을 추가하는 기능입니다.
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');또 다른 게시물은 getWorkingDays (php.net 주석에서 여기에 포함됨)에 대해 언급했지만 일요일에 시작하여 근무일에 끝내면 중단되는 것 같습니다.
다음 사용 (이전 게시물의 getWorkingDays 함수를 포함해야 함)
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);결과를 4가 아닌 5로 제공합니다.

더 간단한이 기능을 사용해 볼 수 있습니다.
function getWorkingDays($startDate, $endDate)
{
$begin = strtotime($startDate);
$end = strtotime($endDate);
if ($begin > $end) {
return 0;
} else {
$no_days = 0;
while ($begin <= $end) {
$what_day = date("N", $begin);
if (!in_array($what_day, [6,7]) ) // 6 and 7 are weekend
$no_days++;
$begin += 86400; // +1 day
};
return $no_days;
}
