关联数组排序数字

Question

我有一个以下格式的关联数组。我需要按降序对数组进行排序，并按照升序对具有相同值的数组进行排序。

$numArray = array(); 
$numArray[0]['Word'] = 'One'; 
$numArray[0]['Number'] = 10.00; 
$numArray[1]['Word'] = 'Two'; 
$numArray[1]['Number'] = 10.00; 
$numArray[2]['Word'] = 'Three'; 
$numArray[2]['Number'] = 10.00; 
$numArray[3]['Word'] = 'Four'; 
$numArray[3]['Number'] = 30.00; 
$numArray[4]['Word'] = 'Five'; 
$numArray[4]['Number'] = 20.00; 
$numArray[5]['Word'] = 'Six'; 
$numArray[5]['Number'] = 10.00; 
$numArray[6]['Word'] = 'Seven'; 
$numArray[6]['Number'] = 20.00; 
$numArray[7]['Word'] = 'Eight'; 
$numArray[7]['Number'] = 20.00; 

请帮我按以下顺序对数组排序。

阵列 （ [0] =>数组 （ [字] =>四 [号码] => 30 ）

 [1] => Array 
      (
       [Word] => Five 
       [Number] => 20 
      ) 

     [2] => Array 
      (
       [Word] => Seven 
       [Number] => 20 
      ) 

     [3] => Array 
      (
       [Word] => Eight 
       [Number] => 20 
      ) 

     [4] => Array 
      (
       [Word] => One 
       [Number] => 10 
      ) 

     [5] => Array 
      (
       [Word] => Two 
       [Number] => 10 
      ) 

     [6] => Array 
      (
       [Word] => Three 
       [Number] => 10 
      ) 

     [7] => Array 
      (
       [Word] => Six 
       [Number] => 10 
      ) 

    )

foreach ($numArray as $key => $row) { 
    $array[$key] = $row['Number']; 
} 


array_multisort($array, SORT_DESC, $numArray); 

这个小PHP代码将至少排序你的数组desc根据数字。 你猜这是你想要的一半。
