按列升序排列php數組

Question

Array 
(
    [content_type] => Array 
     (
      [0] => story 
      [1] => delhi 
      [2] => tez 
     ) 

    [type] => Array 
     (
      [0] => video_id 
      [1] => subcategory 
      [2] => story_id 
     ) 

    [fetch_id] => Array 
     (
      [0] => 32 
      [1] => 32 
      [2] => 2 
     ) 

    [order] => Array 
     (
      [0] => 6 
      [1] => 4 
      [2] => 5 
     ) 

    [label] => Array 
     (
      [0] => dsfs fdsf dsf sdf 
      [1] => dfsdfs 
      [2] => sdfsdfsd 
     ) 

    [link] => Array 
     (
      [0] => fsd fsdf sdf 
      [1] => fsdfsdfdsf 
      [2] => fsdfdsfds 
     ) 

    [record] => Array 
     (
      [0] => 10 
      [1] => 8 
      [2] => 12 
     ) 

) 

上面是數組我必須在order域的基礎上對這個數組進行排序，它應該縮短所有字段，如下面的例子。

$arr['order'][0] = 4; 
$arr['order'][1] = 5; 
$arr['order'][2] = 6; 

$arr['type'][0] = 'subcategory'; 
$arr['type'][1] = 'story_id'; 
$arr['type'][2] = 'video_id'; 

等等.....

Answer 1

你可以試試這個 -

$new = array(); 
// Extract and get the keys as values 
$order = array_flip($array['order']); 
// sort them according to keys 
ksort($order); 
// loop through main array 
foreach($array as $key => $sub_array) { 
    // loop through order 
    foreach ($order as $o) { 
    // store the new value according to order 
    $new[$key][] = $sub_array[$o]; 
    } 
}

Answer 2

一些鮮爲人知的解決方案：

asort($array['order']); 
foreach ($array as $key => $subArray) { 
    $array[$key] = array_replace($array['order'], $subArray); 
} 

對於復位按鍵順序你可能會st使用array_values（）。
