如何通過價值內心深處陣列

          [value] => ppv_provider 
         ) 

       ) 

     ) 

)

我想陣列由陣列由field_device_category值排序。基本上，我想對結果進行分組，但首先我需要確保所有對象都按照field_device_category排序。

提前致謝！

使用usort進行這種分類。它在後臺使用Quicksort並採用用戶定義的函數來比較陣列元素：

usort($array, "complicatedArrayComparer"); 
function complicatedArrayComparer($a,$b) 
{ 
    if ($a['field_device_category'] == $b['field_device_category']) { 
     return 0; 
    } 
    return ($a['field_device_category'] < $b['field_device_category']) ? -1 : 1; 
}

有趣。 ['field_device_category']的條目需要定位到['field_device_category']出現在數組中的位置，是否正確？類似於 - > field_device_category ['und'] [0] ['value']，對不對？ – Hochmania

沒錯。您只需將數組元素作爲函數的參數。你唯一要做的就是比較哪一個數組元素更大，並返回1（第一個更大），0（相等）或-1（第二個）。 –
