Calculer les jours ouvrables

J'ai besoin d'une méthode pour ajouter des "jours ouvrables" en PHP. Par exemple, vendredi 12/5 + 3 jours ouvrables = mercredi 12/10.

Au minimum, j'ai besoin du code pour comprendre les week-ends, mais idéalement, il devrait également tenir compte des jours fériés fédéraux américains. Je suis sûr que je pourrais trouver une solution par la force brute si nécessaire, mais j'espère qu'il existe une approche plus élégante. N'importe qui?

Merci.

Voici une fonction des commentaires des utilisateurs sur la page de fonction date () dans le manuel PHP. C'est une amélioration d'une fonction antérieure dans les commentaires qui ajoute un support pour les années bissextiles.

Entrez les dates de début et de fin, ainsi qu'un tableau de tous les jours fériés qui pourraient être entre les deux, et il renvoie les jours ouvrables sous forme d'entier:

<?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 = $no_full_weeks * 5;
    if ($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
?>

Obtenez le nombre de jours ouvrables sans jours fériés entre deux dates:

Utilisez l'exemple:

echo number_of_working_days('2013-12-23', '2013-12-29');

Production:

3

Fonction:

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;
}

Il y a quelques arguments pour la fonction date () qui devraient aider. Si vous cochez la date ("w"), il vous donnera un numéro pour le jour de la semaine, de 0 pour dimanche à 6 pour samedi. Alors ... peut-être quelque chose comme ...

$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;

Ceci n'est qu'un exemple approximatif d'une possibilité.

Le calcul des vacances n'est pas standard dans chaque État. J'écris une application bancaire pour laquelle j'ai besoin de règles commerciales strictes, mais je ne peux toujours obtenir qu'une norme approximative.

Voici une fonction pour ajouter des jours d'affaires à une date

 echo '<p>'.add_business_days($startdate,7,$holidays,'r');

Un autre article mentionne getWorkingDays (à partir des commentaires de php.net et inclus ici) mais je pense que cela se brise si vous commencez un dimanche et que vous finissez un jour de travail.

En utilisant ce qui suit (vous devrez inclure la fonction getWorkingDays du post précédent)

 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);

Donne le résultat comme 5 pas 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 

La fonction suivante a été utilisée pour générer ce qui précède.

     function get_working_days($startDate,$endDate,$holidays){
      $debug = true;
      $work = 0;
      $nowork = 0;
      $dayx = strtotime($startDate);
      $endx = strtotime($endDate);
      if($debug){
       echo '<h1>get_working_days</h1>';
       echo 'startDate: '.date('r',strtotime( $startDate)).'<br>';
       echo 'endDate: '.date('r',strtotime( $endDate)).'<br>';
       var_dump($holidays);
       echo '<p>Go to work...';
      }
      while($dayx <= $endx){
       $day = date('N',$dayx);
       $date = date('Y-m-d',$dayx);

     if($debug){
      if($day > 5)echo 'weekend';
      else echo 'holiday';
     }
       } else $work++;
       $dayx = strtotime($date.' +1 day');
      }
      if($debug){
      echo '<p>No work: '.$nowork.'<br>';
      echo 'Work: '.$work.'<br>';
      echo 'Work + no work: '.($nowork+$work).'<br>';
      echo 'All seconds / seconds in a day: '.floatval(strtotime($endDate)-strtotime($startDate))/floatval(24*60*60);
      }
      return $work;
     }

    date_default_timezone_set('Europe\London');
     //Example:
     $holidays=array("2012-01-10");
     $startDate = '2012-01-08';
     $endDate = '2012-01-13';
//broken
     echo getWorkingDays( $startDate,$endDate,$holidays);
//works
     echo get_working_days( $startDate,$endDate,$holidays);

Apportez les vacances ...

Vous pouvez essayer cette fonction qui est plus simple.

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;
    }
}

Une fonction pour ajouter ou soustraire des jours ouvrés à une date donnée, cela ne tient pas compte des jours fériés.

function dateFromBusinessDays($days, $dateTime=null) {
  $dateTime = is_null($dateTime) ? time() : $dateTime;
  $_day = 0;
  $_direction = $days == 0 ? 0 : intval($days/abs($days));
  $_day_value = (60 * 60 * 24);

  while($_day !== $days) {
    $dateTime += $_direction * $_day_value;

    $_day_w = date("w", $dateTime);
    if ($_day_w > 0 && $_day_w < 6) {
      $_day += $_direction * 1; 
    }
  }

  return $dateTime;
}

utiliser comme ça ...

echo date("m/d/Y", dateFromBusinessDays(-7));
echo date("m/d/Y", dateFromBusinessDays(3, time() + 3*60*60*24));

Ma version basée sur le travail de @mcgrailm ... a été modifiée car le rapport devait être révisé dans les 3 jours ouvrables, et s'il était soumis un week-end, le comptage commencerait le lundi suivant:

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;
}

Et calculer la différence de deux dates en termes de jours ouvrables:

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;
}

En guise de note, tous ceux qui utilisent 86400 ou 24 * 60 * 60, s'il vous plaît ne le faites pas ... votre heure d'oubli change de l'heure d'hiver / d'été, où un jour n'est pas exactement 24 heures. Bien que le strtotime soit un peu plus lent ('+ 1 day', $ timestamp), il est beaucoup plus fiable.

Tentative brutale de détection du temps de travail - du lundi au vendredi de 8h à 16h:

if (date('N')<6 && date('G')>8 && date('G')<16) {
   // we have a working time (or check for holidays)
}

Vous trouverez ci-dessous le code de travail pour calculer les jours ouvrables à partir d'une date donnée.

<?php
$holiday_date_array = array("2016-01-26", "2016-03-07", "2016-03-24", "2016-03-25", "2016-04-15", "2016-08-15", "2016-09-12", "2016-10-11", "2016-10-31");
$date_required = "2016-03-01";

function increase_date($date_required, $holiday_date_array=array(), $days = 15){
    if(!empty($date_required)){
        $counter_1=0;
        $incremented_date = '';
        for($i=1; $i <= $days; $i++){
            $date = strtotime("+$i day", strtotime($date_required));
            $day_name = date("D", $date);
            $incremented_date = date("Y-m-d", $date);
            if($day_name=='Sat'||$day_name=='Sun'|| in_array($incremented_date ,$holiday_date_array)==true){
                $counter_1+=1;
            }
        }
        if($counter_1 > 0){
            return increase_date($incremented_date, $holiday_date_array, $counter_1);
        }else{
            return $incremented_date;
        }
    }else{
        return 'invalid';
    }
}

echo increase_date($date_required, $holiday_date_array, 15);
?>

//output after adding 15 business working days in 2016-03-01 will be "2016-03-23"

Voici une autre solution sans boucle for pour chaque jour.

$from = new DateTime($first_date);
$to = new DateTime($second_date);

$to->modify('+1 day');
$interval = $from->diff($to);
$days = $interval->format('%a');

$extra_days = fmod($days, 7);
$workdays = ( ( $days - $extra_days ) / 7 ) * 5;

$first_day = date('N', strtotime($first_date));
$last_day = date('N', strtotime("1 day", strtotime($second_date)));
$extra = 0;
if($first_day > $last_day) {
   if($first_day == 7) {
       $first_day = 6;
   }

   $extra = (6 - $first_day) + ($last_day - 1);
   if($extra < 0) {
       $extra = $extra * -1;
   }
}
if($last_day > $first_day) {
    $extra = $last_day - $first_day;
}
$days = $workdays + $extra

Pour les vacances, créez un tableau de jours dans un format que date () peut produire. Exemple:

// I know, these aren't holidays
$holidays = array(
    'Jan 2',
    'Feb 3',
    'Mar 5',
    'Apr 7',
    // ...
);

Utilisez ensuite les fonctions in_array () et date () pour vérifier si l'horodatage représente un jour férié:

$day_of_year = date('M j', $timestamp);
$is_holiday = in_array($day_of_year, $holidays);

J'ai eu ce même besoin, j'ai commencé avec le premier exemple de Bobbin et j'ai fini avec ça

  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);
  }

hth quelqu'un

Variante 1:

<?php
/*
 * Does not count current day, the date returned is 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>0) {
        $timestamp += 86400;
        if (date('N', $timestamp)<6) $bDays--;
    }
    return $timestamp;
}

Variante 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;
}

Variante 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;
}

Les considérations supplémentaires relatives aux vacances peuvent être prises en compte en utilisant des variantes de ce qui précède en procédant comme suit. Remarque! assurez-vous que tous les horodatages sont à la même heure de la journée (c'est-à-dire minuit).

Faites un tableau de dates de vacances (sous forme d'horodatage unixtimestamp), c'est-à-dire:

$holidays = array_flip(strtotime('2011-01-01'),strtotime('2011-12-25'));

Modifier la ligne:

if (date('N', $timestamp)<6) $bDays--;

être :

if (date('N', $timestamp)<6 && !isset($holidays[$timestamp])) $bDays--;

Terminé!

<?php
/*
 * Does not count current day, the date returned is the last business day
 * Requires PHP 5.1 (Using ISO-8601 week)
 */

function businessDays($timestamp = false, $bDays = 2) {
    if($timestamp === false) $timestamp = strtotime(date('Y-m-d',time()));
    $holidays = array_flip(strtotime('2011-01-01'),strtotime('2011-12-25'));
    while ($bDays>0) {
        $timestamp += 86400;
        if (date('N', $timestamp)<6 && !isset($holidays[$timestamp])) $bDays--;
    }
    return $timestamp;
}

<?php 
function AddWorkDays(){
$i = 0;
$d = 5; // Number of days to add

    while($i <= $d) {
    $i++;
        if(date('N', mktime(0, 0, 0, date(m), date(d)+$i, date(Y))) < 5) {
            $d++;
        }
    }
    return date(Y).','.date(m).','.(date(d)+$d);
}
?>

Voici une solution récursive. Il peut facilement être modifié pour ne conserver et renvoyer que la dernière date.

//  Returns a $numBusDays-sized array of all business dates, 
//  starting from and including $currentDate. 
//  Any date in $holidays will be skipped over.

function getWorkingDays($currentDate, $numBusDays, $holidays = array(), 
  $resultDates = array())
{
  //  exit when we have collected the required number of business days
  if ($numBusDays === 0) {
    return $resultDates;
  }

  //  add current date to return array, if not a weekend or holiday
  $date = date("w", strtotime($currentDate));
  if ( $date != 0  &&  $date != 6  &&  !in_array($currentDate, $holidays) ) {
    $resultDates[] = $currentDate;
    $numBusDays -= 1;
  }

  //  set up the next date to test
  $currentDate = new DateTime("$currentDate + 1 day");
  $currentDate = $currentDate->format('Y-m-d');

  return getWorkingDays($currentDate, $numBusDays, $holidays, $resultDates);
}

//  test
$days = getWorkingDays('2008-12-05', 4);
print_r($days);

calculer les jours ouvrables entre deux dates, y compris les jours fériés et la semaine de travail personnalisée

La réponse n'est pas si triviale - donc ma suggestion serait d'utiliser une classe où vous pouvez configurer plus que de compter sur une fonction simpliste (ou en supposant une locale et une culture fixes). Pour obtenir la date après un certain nombre de jours ouvrables, vous:

1. vous devez spécifier les jours de la semaine où vous travaillerez (par défaut MON-VEN) - la classe vous permet d'activer ou de désactiver chaque jour de la semaine individuellement.
2. besoin de savoir que vous devez tenir compte des jours fériés (pays et état) pour être précis
   • par exemple https://github.com/khatfield/php-HolidayLibrary/blob/master/Holidays.class.php
   • ou coder en dur les données: par exemple à partir de http://www.feiertagskalender.ch/?hl=fr
   • ou payez pour data-API http://www.timeanddate.com/services/api/holiday-api.html

Approche fonctionnelle

/**

 * @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;

C'est une autre solution, c'est près de 25% plus rapide que de vérifier les vacances avec in_array:

/**
 * Function to calculate the working days between two days, considering holidays.
 * @param string $startDate -- Start date of the range (included), formatted as Y-m-d.
 * @param string $endDate -- End date of the range (included), formatted as Y-m-d.
 * @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));
}

Cet extrait de code est très facile à calculer le jour ouvrable sans week-end ni jours fériés:

function getWorkingDays($startDate,$endDate,$offdays,$holidays){
$endDate = strtotime($endDate);
$startDate = strtotime($startDate);
$days = ($endDate - $startDate) / 86400 + 1;
$counter=0;
for ($i = 1; $i <= $days; $i++) {
    $the_first_day_of_week = date("N", $startDate);
    $startDate+=86400;
if (!in_array($the_first_day_of_week, $offdays) && !in_array(date("Y-m-
d",$startDate), $holidays)) {
$counter++;
}

}   
return $counter;
}
//example to use
$holidays=array("2017-07-03","2017-07-20");
$offdays=array(5,6);//weekend days Monday=1 .... Sunday=7
echo getWorkingDays("2017-01-01","2017-12-31",$offdays,$holidays)

Je sais que je suis en retard à la fête, mais j'utilise cet ancien ensemble de fonctions de Marcos J. Montes pour déterminer les jours fériés et les jours ouvrables. Il a pris le temps d'ajouter un algorithme de 1876 pour Pâques et il a ajouté toutes les grandes vacances américaines. Cela peut facilement être mis à jour pour d'autres pays.

Le add_business_days a un petit bogue. Essayez ce qui suit avec la fonction existante et la sortie sera un samedi.

Date de début = vendredi Jours ouvrables à ajouter = 1 Tableau des jours fériés = Ajouter la date du lundi suivant.

J'ai corrigé cela dans ma fonction ci-dessous.

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);}

Je fais juste fonctionner ma fonction sur la base du code Bobbin et mcgrailm, en ajoutant des choses qui ont fonctionné parfaitement pour moi.

function add_business_days($startdate,$buisnessdays,$holidays,$dateformat){
    $enddate = strtotime($startdate);
    $day = date('N',$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);
}

// as a parameter in in_array function we should use endate formated to 
// compare correctly with the holidays array.

Une amélioration de la fonction offerte par James Pasta ci-dessus, pour inclure tous les jours fériés fédéraux, et pour corriger le 4 juillet (a été calculé comme 4 juin ci-dessus!), Et pour inclure également le nom du jour férié comme clé du tableau ...

Je viens de terminer d'écrire une API qui peut être utilisée pour manipuler les jours ouvrables (aucune de ces solutions n'a vraiment fonctionné pour ma situation :-); lien vers lui ici au cas où quelqu'un d'autre le trouverait utile

Classe PHP pour calculer les jours ouvrables

Merci à Bobbin, mcgrailm, Tony, James Pasta et quelques autres qui ont posté ici. J'avais écrit ma propre fonction pour ajouter des jours ouvrables à une date, mais je l'ai modifiée avec du code que j'ai trouvé ici. Cela gérera la date de début étant un week-end / jour férié. Cela gérera également les heures d'ouverture. J'ai ajouté quelques commentaires et décomposé le code pour le rendre plus facile à lire.

<?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...

function getNationalAmericanHolidays($year) {
$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) ),
    'Independance Day' => $year . "-07-04",
    'Labor Day' => "". date("Y-m-d",strtotime("first Monday of September " . $year) ),
    'Columbus Day' => "". date("Y-m-d",strtotime("second Monday of October " . $year) ),
    'Veterans Day' => $year . "-11-11",
    'Thanksgiving Day' => "". date("Y-m-d",strtotime("fourth Thursday of November " . $year) ),
    'Christmas Day' => $year . "-12-25"
);
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.

//Go to next day if after 5 pm (5 pm = 17)
if (date(G) >= 17) {
    $start_date = date("Y-m-d", strtotime("+ 1 day")); //Tomorrow
} else {
    $start_date = date("Y-m-d"); //Today
}

//Get the holidays for the current year and also for the next year
$this_year = getNationalAmericanHolidays(date('Y'));
$next_year = getNationalAmericanHolidays(date('Y', strtotime("+12 months")));
$holidays = array_merge($this_year, $next_year);

//The number of days to count
$days_count = 10;

echo count_business_days($start_date, $days_count, $holidays);

?>

Personnellement, je pense que c'est une solution plus propre et plus concise:

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;
}

Envoyez simplement la newdate proposée à cette fonction.
