"Windows users cannot use the %V specifier for strftime as it is not implemented in the OS.
Following is a possible workaround to get the ISO weeknumber:
function ISOWeek($y, $m, $d)
{
$week=strftime("%W", mktime(0, 0, 0, $m, $d, $y));
$dow0101=getdate(mktime(0, 0, 0, 1, 1, $y));
if ($dow0101["wday"]>1 &&
$dow0101["wday"]<5)
$week++;
elseif ($week==0)
$week=53;
return(substr("00" . $week, -2));
}"
This function, however, does not take into concideration that a week starts on monday and not sunday
according to that ISO-standard. Also for weeks having Jan 1 as later than Thursday the week number
is not 1 but the number of the last week in the previous year. I´m working on a solution.
