$borrowdate = new Datetime($row['date_return'],new DateTimeZone('Asia/Manila'));
$returndate = new Datetime($row['due_date'],new DateTimeZone('Asia/Manila'));
$currentdate = new Datetime('Asia/Manila');
$returndate->setTime(0,0);
$currentdate->setTime(0,0);
$borrowdate->setTime(0,0);
$interval = DateInterval::createFromDateString('1 day');
$period = new DatePeriod($returndate, $interval, $borrowdate);
$borrowdate->format("D");
$weekendDays = 0;
$totalDays = 0;
$holiDays = 0;
$query_holiday =mysqli_query($dbcon,"SELECT * FROM holiday_tbl");
while($row=mysqli_fetch_array($query_holiday)){
$holi = $row ['holiday'];
foreach ($period as $p )
{
$totalDays++;
if($p->format( "w" )== 0 or $p->format( "w" )==6 ) $weekendDays++;
if($p->format('Y-m-d') == $holi) $holiDays++;
}
}
echo "<p>Total days: $totalDays</p><p>Weekend days: $weekendDays </p> <p> Holidays: $holiDays </p>";
$fines = ($totalDays - $weekendDays - $holiDays) * 5;
echo "₱ ". $fines;
$fi = $row['borrow_details_id'];
mysqli_query($dbcon,"update borrowdetails set fines='$fines' where borrow_details_id = '$fi'");
