Sasha ... I'm sending this again to the list as it seemed to bounce from
your address
the way I was doing it prevents unique values from being created in the
first place. The only array that gets overwritten is one that would be the
same any way
while ($row = mysql_fetch_array($result))
{ $month = date("m", $row['timestamp']);
$year = date("Y", $row['timestamp']);
$archive_date = mktime(1,1,1,$month,1,$year);
$archive_nav[$archive_date] = $archive_date;
}
... ensures that if the date has already been added to the array then it
overwrites the existing one instead of adding a new element.
