RE: [PHP] Removeing duplicates inside for/foreach loop.

[Niccolo Machiavelli]

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]);
}

if (count($order_data) > 0) {
$order_list = implode(', ',
$order_data);
} else {
$order_list = '';
}

}
}

[PHP] Removeing duplicates inside for/foreach loop.

[Niccolo Machiavelli]

$array = array(

  1 => array("order_number" => "10DA0DDEDAF97DB", "order_payment_first_name"
=>  "Mike", "order_payment_last_name" =>  "Smith"),

  2 => array("order_number" => "10DA0DDEDAF97DB", "order_payment_first_name"
=>  "Mike", "order_payment_last_name" =>  "Smith"),

  3 => array("order_number" => "45Y3453245T23T5", "order_payment_first_name"
=>  "Steve", "order_payment_last_name" =>  "Jobs"),

  4 => array("order_number" => "34RTB345T45T456", "order_payment_first_name"
=>  "Frank", "order_payment_last_name" =>  "Capra"),

  5 => array("order_number" => "567U457645645Y6", "order_payment_first_name"
=>  "John", "order_payment_last_name" =>  "Doe"),

  6 => array("order_number" => "7698234T456M963", "order_payment_first_name"
=>  "Bill", "order_payment_last_name" =>  "Williams"));

 

echo('');

print_r($array);

echo('');

 

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. 

 

 

Thanks
