since you are getting your information from a db, use
SELECT DISTINCT order_number,
This will ensure that only unique order_numbers are returned
sort($order_data);
if ($count = count($order_data)) {
for ($i = 2; $i < $count; $i++) {
if ($order_data[$i]['order_number'] ==

I'm firly certain array unique won't can't handle dimensional arrays. This
is what I have for code it almost works
$order_data = array();
while ($row = $db->fetchRow($result)) {
$order_data[] = '' .
$row['order_payment_first_name'] . ' ' . $row['order_payment_last_name'] .
'';
}
$db->freeresult($result);
sort($order_data);
if ($count = count($order_data)) {
for ($i = 2; $i < $count; $i++) {
if ($order_data[$i]['order_number'] ==
$order_data[$i-1]['order_number']) {
unset($order_data[$i-1]);

It looks like the array is sorted.
In pseudo code
for i = 2 to n
if x[1].order = x[i-1].order then
unlink x[i-1]
