$year='2014';//год
echo date('W',mktime(0,0,0,12,31,$year));

Writing great

function getCountWeek($year)
{
    $date=date('w',mktime(0,0,0,12,31,$year));
    $day=($date<4?31-$date:31);
    return date('W',mktime(0,0,0,12,$day,$year))+($date<4?1:0);    
}

Update

Who cares. According to ISO 8601, the first week is not the one that starts on the first of January, but the one that contains the first Thursday of the year. I'm in shock myself)
