Answer 1

I solved this like this:

function getWeekOfYear( DateTime $date ) {

        $dayOfweek = intval( $date->format('w') );

        if( $dayOfweek == 0 ) {
            $date->add(new DateInterval('P1D'));
        } 

        $weekOfYear = intval( $date->format('W') );

        return $weekOfYear;
}
