好吧，所以我有这个数组，让我们叫它$ array。php array_multisort不排序我的多维数组

我现在有一个函数可以用多个键对多维数组进行排序。

function sort_multiple_keys($array,$key1,$key1_sort = SORT_DESC,$key2,$key2_sort = SORT_ASC){ 

    $sort = array(); 
    if(count($array) > 0){ 
     foreach($array as $k=>$v) { 
      $first[$k] = $v[$key1]; 
      $second[$k] = $v[$key2]; 
     } 

     array_multisort($first, $key1_sort, $second, $key2_sort, $array); 

    } 

    unset($sort); 
}

所以，我会按事件类型，然后APPOINTMENT_FROM日期进行排序。所以我运行这个功能：

sort_multiple_keys($array,'event_type',SORT_DESC,'appointment_from',SORT_ASC);

但没有什么？

任何帮助？

您的函数是否需要返回值？ – andrewsi 2013-04-11 18:03:33

不，它只是运行一个数组排序..但在我能够做到这一点之前，我必须进行转换。我从它得到的例子是从这里： http://stackoverflow.com/questions/3232965/sort-multidimensional-array-by-multiple-keys – 2013-04-11 18:12:16

你实际上并没有从你的排序函数中返回一个值。

您可以在末尾return $array;或者将其作为参考传入，因此该函数可以在原始实例上工作，而不是在副本上工作;为此，您需要将函数定义更改为：

function sort_multiple_keys(&$array,$key1,$key1_sort = SORT_DESC,$key2,$key2_sort = SORT_ASC){ 
          ^tells PHP that this variable is by reference
