Answer 1

You can use the "while statement", looping until get enough 5 days. Each time looping get & check one next day is in the holiday list or not.

Here is the the example:

$holidayDates = array(
    '2016-03-26',
    '2016-03-27',
    '2016-03-28',
    '2016-03-29',
    '2016-04-05',
);

$count5WD = 0;
$temp = strtotime("2016-03-25 00:00:00"); //example as today is 2016-03-25
while($count5WD<5){
    $next1WD = strtotime('+1 weekday', $temp);
    $next1WDDate = date('Y-m-d', $next1WD);
    if(!in_array($next1WDDate, $holidayDates)){
        $count5WD++;
    }
    $temp = $next1WD;
}

$next5WD = date("Y-m-d", $temp);

echo $next5WD; //if today is 2016-03-25 then it will return 2016-04-06 as many days between are holidays
