You're not sorting the total results, you are sorting every 'row' in the
field by value, of which it has only one:
print_r($order_list_array):
gives:
Array{
[0] => 'order_06-03-2006-001'
}
You COULD:
$list = array();
while ($order_list_array = mysql_fetch_array($order_list_query)){
$list[] = $order_list_array[0];
}
rsort($list);
foreach($list as $order){
echo $order.'<br />';
}
Unfortunately, as far as I know, it's not possible to sort the tables in the
query directly.
I wonder what the use is to have a table per order though, any special
reason? I don't know wether it's possible for you, but I'd consider using a
different table structure, where orders a rows (perhaps with links to other
tables). That would save a lot of fiddling about, and makes querying the
database also a bit faster I'd believe.
