Answer 2

function total_week_between_two_dates($dt1, $dt2) {
    $date1 = new DateTime($dt1);
    $date2 = new DateTime($dt2);

    $interval = $date1->diff($date2);

    return floor(($interval->days) / 7);
}

$dt1 = '1/1/2019';
$dt2 = '3/12/2019';

echo total_week_between_two_dates($dt1, $dt2);

 
/*
run:
      
10
     
*/
