Php.Advance weekly calendar one week

I have written a script that displays a calendar week by week that the user can chose to go back or forward a week at a time. Everything works great except the first week of every year still displays the wrong year and the 31st December shows as 02/01. It seems that only week 1 is affected, the days are correct again in week and onwards

<?
if(isset($_POST['add_week'])){
     $last_week_ts = strtotime($_POST['last_week']);
     $display_week_ts = $last_week_ts + (3600 * 24 * 7);
} else if (isset($_POST['back_week'])) {
     $last_week_ts = strtotime($_POST['last_week']);
     $display_week_ts = $last_week_ts - (3600 * 24 * 7);
} else {
    $display_week_ts = floor(time() / (3600 * 24)) * 3600 * 24;
}

    $week_start = date('d-m-Y', $display_week_ts);
    $week_number = date("W", $display_week_ts);
    $year = date("Y", $display_week_ts);

echo $week_start.' '.$week_number.' '.$year;
?>

<table name="week">
    <tr>
<?
for($day=1; $day<=7; $day++)
{
    echo '<td>';
    echo date('d-m-Y', strtotime($year."W".$week_number.$day))." | \n";
    echo '</td>';
}
?>
</tr>
<tr>
<form name="move_weeks" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="hidden" name="last_week" value="<? echo $week_start; ?>" />
<td colspan="7"><input type="submit" name="back_week" value="back_week" /><input type="submit" name="add_week" value="add_week" />
</td>
</form>
</tr>
</table>

Any help will be appreciated

Answer 1

As suggested in the answer to the original question, you need to not use the week number and year number stuff.

If at the end of the day, you want to be able to list seven days for the week, just do not use this section of code at all:

$week_number = date("W", $display_week_ts);
$year = date("Y", $display_week_ts);

echo $week_start.' '.$week_number.' '.$year;

And replace the loop that echos out with the loop suggested in the original question.
