數組排序多維的關鍵PHP

Question

我有此數組：

Array 
(
    [26] => Array 
    (
     [total_auctions] => 1 
     [total_price] => 0 
    ) 

    [24] => Array 
    (
     [total_auctions] => 0 
     [total_price] => 0 
    ) 

    [25] => Array 
    (
     [total_auctions] => 0 
     [total_price] => 0 
    ) 
) 

我想這個數組排序是：

Array 
(
[24] => Array 
(
    [total_auctions] => 0 
    [total_price] => 0 
) 
[25] => Array 
(
    [total_auctions] => 0 
    [total_price] => 0 
) 

[26] => Array 
(
    [total_auctions] => 1 
    [total_price] => 0 
) 
) 

我試着用array_multisort，但不起作用。你能幫我嗎 ？ Thx提前。我不明白問題出在哪裏，應該正常工作

只需使用kso​​rt（）對任何數組鍵

<?php 
$arr = array(
    '26' => array('total_auctions' => 1,'total_price' => 0), 
    '24' => array('total_auctions' => 0,'total_price' => 0), 
    '25' => array('total_auctions' => 0,'total_price' => 0) 
); 
ksort($arr); 
print '<pre>';print_r($arr); 
exit; 
?>
