Get date range between two dates excluding weekends - php

Question

Given the following dates:
6/30/2010 - 7/6/2010
and a static variable:
$h = 7.5
I need to create an array like:
Array ( [2010-06-30] => 7.5 [2010-07-01] => 7.5 => [2010-07-02] => 7.5 => [2010-07-05] => 7.5 => [2010-07-06] => 7.5)
Weekend days excluded.
No, it's not homework...for some reason I just can't think straight today.

Answer 1

For PHP >= 5.3.0, use the DatePeriod class. It's unfortunately barely documented.
$start = new DateTime('6/30/2010');
$end = new DateTime('7/6/2010');
$oneday = new DateInterval("P1D");
$days = array();
$data = "7.5";
/* Iterate from $start up to $end+1 day, one day in each iteration.
We add one day to the $end date, because the DatePeriod only iterates up to,
not including, the end date. */
foreach(new DatePeriod($start, $oneday, $end->add($oneday)) as $day) {
$day_num = $day->format("N"); /* 'N' number days 1 (mon) to 7 (sun) */
if($day_num < 6) { /* weekday */
$days[$day->format("Y-m-d")] = $data;
}
}
print_r($days);

Answer 2

The simplest method:
$start = strtotime('6/30/2010');
$end = strtotime('7/6/2010');
$result = array();
while ($start <= $end) {
if (date('N', $start) <= 5) {
$current = date('m/d/Y', $start);
$result[$current] = 7.5;
}
$start += 86400;
}
print_r($result);
UPDATE: Forgot to skip weekends. This should work now.

Answer 3

This is gnud's answer but as a function (also added an option to exclude the current day from the calculation):
(examples below)
public function getNumberOfDays($startDate, $endDate, $hoursPerDay="7.5", $excludeToday=true)
{
// d/m/Y
$start = new DateTime($startDate);
$end = new DateTime($endDate);
$oneday = new DateInterval("P1D");
$days = array();
/* Iterate from $start up to $end+1 day, one day in each iteration.
We add one day to the $end date, because the DatePeriod only iterates up to,
not including, the end date. */
foreach(new DatePeriod($start, $oneday, $end->add($oneday)) as $day) {
$day_num = $day->format("N"); /* 'N' number days 1 (mon) to 7 (sun) */
if($day_num < 6) { /* weekday */
$days[$day->format("Y-m-d")] = $hoursPerDay;
}
}
if ($excludeToday)
array_pop ($days);
return $days;
}
And to use it:
$date1 = "2012-01-12";
$date2 = date('Y-m-d'); //today's date
$daysArray = getNumberOfDays($date1, $date2);
echo 'hours: ' . array_sum($daysArray);
echo 'days: ' . count($daysArray);

Answer 4

This is OOP approach, just in case. It returns an array with all of dates, except the weekends days.
class Date{
public function getIntervalBetweenTwoDates($startDate, $endDate){
$period = new DatePeriod(
new DateTime($startDate),
new DateInterval('P1D'),
new DateTime($endDate)
);
$all_days = array();$i = 0;
foreach($period as $date) {
if ($this->isWeekend($date->format('Y-m-d'))){
$all_days[$i] = $date->format('Y-m-d');
$i++;
}
}
return $all_days;
}
public function isWeekend($date) {
$weekDay = date('w', strtotime($date));
if (($weekDay == 0 || $weekDay == 6)){
return false;
}else{
return true;
}
}
}
$d = new Date();
var_dump($d->getIntervalBetweenTwoDates('2015-08-01','2015-08-08'));
