:) hi evrybody

i found this scripts that calculate diference between 2 dates not includind sunday and holidays

 

function getWorkingDays($startDate,$endDate,$holidays){
    //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.
    $days = (strtotime($endDate) - strtotime($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
    $the_first_day_of_week = date("N",strtotime($startDate));
    $the_last_day_of_week = date("N",strtotime($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) $no_remaining_days--;
    }
    else{
        if ($the_first_day_of_week <= 6) $no_remaining_days--;
        //In the case when the interval falls in two weeks, there will be a Sunday for sure
        $no_remaining_days--;
    }

    //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 (strtotime($startDate) <= $time_stamp && $time_stamp <= strtotime($endDate) && date("N",$time_stamp) != 6 && date("N",$time_stamp) != 7)
            $workingDays--;
    }

    return $workingDays;
}

//Example:

$holidays=array("2006-12-25","2006-12-26","2008-01-01");

echo getWorkingDays("2008-01-01","2008-01-31",$holidays);

so as yu see i wil have result  22 days

but i'm looking for is display resulut like this

week 1: 3 days;

week 2: 5days;

week 3; 5 days;

week 4  5 days;

week 5  4 days;

and i can't see how i use this functions if i have many days

for exemple

start days      |    end days   

2008-01-01            2008-01-31

2008-01-05            2008-02-02

 

thank for helping :)
