PHP：排序多维数组

Question

我有多维数组，如：

Array 
(
    [name] => Array 
     (
      [0] => South Africa 
      [1] => Australia 
      [2] => Egypt 
     ) 

    [img] => Array 
     (
      [0] => sa-flag.jpg 
      [2] => au-flag.jpg 
      [1] => eg-flag.jpg 
     ) 
) 

，我想对它进行排序按字母顺序，使得其输出将完全一样：

Array 
(
    [name] => Array 
     (
      [0] => Australia 
      [1] => Egypt 
      [2] => South Africa 
     ) 

    [img] => Array 
     (
      [0] => au-flag.jpg 
      [2] => eg-flag.jpg 
      [1] => sa-flag.jpg 
     ) 
) 

我做不到能够对两个键进行排序以使国名与国旗同步。

请在下面找到解决方案

$kd = array(
'name' => array(
     '0' => 'South Africa', 
     '1' => 'Australia', 
     '2' => 'Egypt', 
    ), 

'img' => array 
    (
     '0' => 'sa-flag.jpg', 
     '2' => 'au-flag.jpg', 
     '1' => 'eg-flag.jpg', 
    ), 
); 
array_multisort($kd['name'], SORT_ASC, SORT_STRING,$kd['img'], SORT_ASC, SORT_STRING); 
echo '<pre>'; 
print_r($kd); 

查找下面的核心理念

试试这个

$arr = array_multisort($array);
