Question

im trying to create a function that takes a $start_date as parameter and it should calculate which week number we are in i.e

for instance $start_date equals 2012-08-16

private function get_week_number($start_date){
        // get current date
        // caluculate the difference between start_date and current_date
        // determine which week we are in 1, 2 or 3
        // return $week 
    }

how can i implement this in php? thanks

Answer 1

function get_week_number($start_date){
    $date = date('U', strtotime($start_date));
    $now = date('U');
    return ceil(($now-$date)/60/60/24/7);
}

echo get_week_number('2012-08-16');
