排序多維數組由不同的值有條件

Question

我的下一個multidimensioanl陣列（這是相當長的，但我在這裏複製的第一個元素）：

[0] => Array 
    (
     [cpt] => Product 
     [tax] => Type A 
     [year] => 2012 
    ) 

[1] => Array 
    (
     [cpt] => Product 
     [tax] => Type B 
     [year] => 2012 
    ) 

[2] => Array 
    (
     [cpt] => Product 
     [tax] => Type C 
     [year] => 2011 
    ) 

[3] => Array 
    (
     [cpt] => Product 
     [tax] => Type C 
     [year] => 2011 
    ) 

[4] => Array 
    (
     [cpt] => Product 
     [tax] => Type D 
     [year] => 2015 
    ) 

[5] => Array 
    (
     [cpt] => Review 
     [tax] => Figure 
     [year] => 2014 
    ) 

[6] => Array 
    (
     [cpt] => Review 
     [tax] => Sample 
     [year] => 2012 
    ) 

[7] => Array 
    (
     [cpt] => Review 
     [tax] => Figure 
     [year] => 2012 
    ) 

[8] => Array 
    (
     [cpt] => Review 
     [tax] => Picture based 
     [year] => 2015 
    ) 

[9] => Array 
    (
     [cpt] => Review 
     [tax] => Figure 
     [year] => 2012 
    ) 

[10] => Array 
    (
     [cpt] => Review 
     [tax] => Picture based 
     [year] => 2013 
    ) 
[11] => Array 
    (
     [cpt] => Template 
     [tax] => L 
     [year] => 2013 
    ) 

[12] => Array 
    (
     [cpt] => Template 
     [tax] => L 
     [year] => 2015 
    ) 

[13] => Array 
    (
     [cpt] => Template 
     [tax] => M 
     [year] => 2011 
    ) 

[14] => Array 
    (
     [cpt] => Template 
     [tax] => S 
     [year] => 2011 
    ) 

，我需要的「中華映管」價值首先對其進行排序，然後按「稅」值，最後按「年」計算。

問題是，「cpt」和「tax」的排序順序應該是自定義順序，而不是按字母順序。

而好消息是：

• 總是會產生由「中華映管」完全排序的數組（你可以看到 ）。所以我不在乎分類。
• 對於特定的「cpt」，即「Review」，我只需要應用這些排序更改（首先在「稅收」中，然後 「下一年」）。

這是我的代碼，但它是無效的，因爲它也改變了「cpt」順序。

$sort_tax = array("Sample","Figure","Picture based"); 
usort($the_array, function ($a, $b) use ($sort_tax) { 
    $pos_a = array_search($a['tax'], $sort_tax); 
    $pos_b = array_search($b['tax'], $sort_tax); 
    $result = $pos_a - $pos_b; 
    if ($result == 0) { 
     $difference = $a['year'] - $b['year']; 
     if ($difference >= 0) { 
      $value = 0; 
     } else { 
      $value = 1; 
     } 
     return $value; 
    } else { 
     return $pos_a - $pos_b; 
    } 
}); 

任何想法？ 非常感謝提前！

Answer 1

$array = array(); 
foreach($array_name as $arr){ 
    $array['cpt'] = $arr['cpt']; 
    $array['tax'] = $arr['tax']; 
    $array['year'] = $arr['year']; 
} 

array_multisort($array['tax'], SORT_DESC, $array['year'], SORT_ASC,$Your_array_name);
