Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
http://php.net/date, see the "W" modifier, which
returns the ISO week
of the year. There is nothing wrong here.

For example the function give for sunday, 01.01.2006 the week number

$aHour = 60*60; $aDay = $aHour * 24;
for ($d = 0; $d <= 5; $d++) {
$Day00 = $Dez05 + $d * $aDay;
for ($ih = 0; $ih < 3; $ih++) {
$h=8*$ih;
$TS = $Day00 + $h * $aHour;
$DAY = date("D",$TS); $nrDAY = date("d",$TS);
$HR = date("H",$TS); $MIN = date("i",$TS);
$MNTH = date("m",$TS); $YEAR = date("y",$TS);
$WEEK = date("W",$TS); $WEEK = sprintf ("%02d", $WEEK);
$sd = sprintf ("%02d", $d);
$sh = sprintf ("%02d", $h);
echo "$TS ($sd, $sh) --> week = <b>$WEEK</b>, $DAY,
$nrDAY.$MNTH.$YEAR, $HR.$MIN </br>";
}
}
?>
