yii2 How to count days between dates exclude weekends and holiday - php

Question

Okay first of all, before some of you might put this question into a duplicate question. i have been go through many questions related to my question. But it seems like those questions cannot solve my problem. i want to find days between 2 dates excluding weekend and holidays. the questions that i have been go through declare the variable of $holiday in array and initialize the value in that array.
Below is my code in LeaveapplicationController.phpfor finding days exclude weekends
$date1 = $model->startDate;
$date2 = $model->endDate;
$date1 = strtotime($date1);
$date2 = strtotime($date2);
//Initialized public holiday
$holidays = array("2020-01-21", "2020-01-22", "2020-01-23");
$days = ($date2 - $date1)/86400 + 1;
$fullWeek = floor($days/7);
$remainDay = fmod($days,7);
$firstDay = date("N", $date1);
$lastDay = date("N", $date2);
if($firstDay <= $lastDay){
if($firstDay <= 6 && 6 <= $lastDay) $remainDay--;
if($firstDay <= 7 && 7 <= $lastDay) $remainDay--;
}
else
{
if($firstDay == 7){
$remainDay--;
if($lastDay == 6){
$remainDay--;
}
}
else{
$remainDay -= 2;
}
}
$workDay = $fullWeek * 5;
if($remainDay > 0)
{
$workDay += $remainDay;
}
foreach($holidays as $holiday){
$timeStamp = strtotime($holiday);
if($date1 <= $timeStamp && $timeStamp <= $date2 && date("N", $timeStamp) != 6 && date("N", $timeStamp) != 7)
$workDay--;
}
$model->no_of_days=$workDay;
$model->save();
So, i have tried with holiday that has been initialized with some values. In my case, i want to replace that $holiday=array() with data from another table of database. Is there any best way to do it?

Using DateTime
$start = new \DateTime($model->startDate); //2020-01-01
$end = new \DateTime($model->endDate); //2020-01-31
$endDate = $end->format('Y-m-d');
$interval = new \DateInterval('P1D');
$end->add($interval);
$period = new \DatePeriod($start, $interval, $end);
foreach ($period as $date) {
$allDates[] = [
'date' => $date->format('Y-m-d'),
'dayNo' => $date->format('N'),
];
}
//Initialized public holiday
$holidays = HolidayModelName::find()
->select('date')
->where(['between', 'date', $start->format('Y-m-d'), $endDate])
->indexBy('date')
->column();
$workDay = 0;
foreach ($allDates as $value) {
$isWeekOff = $value['dayNo'] == 6 || $value['dayNo'] == 7;
if (!$isWeekOff && !isset($holidays[$value['date']])) {
$workDay++;
}
}
// Result : 20 Work Days
