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[] = '<a href="'.setup_uri('orders').'?id=' . $row['order_number'] .

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'] == $order_data[$i-1]['order_number']) {

        			unset($order_data[$i-1]);

} if (count($order_data) > 0) { $order_list = implode(', ', $order_data); } else { $order_list = ''; } } } -----Original Message----- From: tedd [mailto:tedd.sperling@gmail.com] Sent: Tuesday, July 15, 2008 12:12 PM To: php-general@lists.php.net Subject: Re: [PHP] Removeing duplicates inside for/foreach loop.

My question is I want to remove duplicate order numbers in other words

ditch

*one* of the Mike Smith rows there's a duplicate order number there. And I need to do it in either a for/foreach loop. Somehow there's got to be a simple way to check and only output non duplicate order numbers while I'm looping thru the data. Any help would be greatly appreciated.
