Get date range between two dates excluding weekends

Question

Given the following dates:

6/30/2010 - 7/6/2010

and a static variable:

$h = 7.5

I need to create an array

Answer 1

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);
