Usort通过重复排序多维数组值

Question

我有一个数组

[0] => ['name' => John, city => NY, street => WallStreet ..some anouther fields] 
[1] => ['name' => Bill, city => FI, street => smstr.. some anouther fields] 
[2] => ['name' => John, city => NY, street => WallStreet ..some anouther fields] 
[3] => ['name' => Bill, city => FI, street => smstr ..some anouther fields] 
[4] => ['name' => 4, city => 4, street => 4 ..some anouther fields] 

我需要对它进行排序，以让所有重复名称的城市和街道的字段是在阵列的顶部或只是在顺序

我想

[] => ['name' => John, city => NY, street => WallStreet..some anouther fields] 
[] => ['name' => John, city => NY, street => WallStreet ..some anouther fields] 
[] => ['name' => Bill, city => FI, street => smstr ..some anouther fields] 
[] => ['name' => Bill, city => FI, street => smstr ..some anouther fields] 
[] => ['name' => 4, city => 4, street => 4 ..some anouther fields] 

我想usort

usort($sorted, function($a, $b) { 
      if ($a['name'] == $b['name'] && 
       $a['city'] == $b['city'] && 
       $a['street'] == $b['street'] 
      ){ 
       return 1; 
      } 
      else { 
       return -1; 
      } 
     }); 

使用

但它不适用于PHP 5.3，任何人都可以提出解决方案吗？

P/S，我用PHP 5.3的工作:(

Answer 1

可以映射到一个数组内爆的价值观，那种下降，并通过该数组排序原文：

array_multisort(array_map(function($v) { 
           return implode('-', $v); 
          }, $array), 
       SORT_DESC, $array); 

为了打破它和理解件：

// Build an array of the values in each sub array 
// John-NY-WallStreet 
$sorter = array_map(function($v) { return implode('-', $v); }, $array); 
print_r($sorter); 
// Sort that descending sorting the original array the same 
array_multisort($sorter, SORT_DESC, $array); 

这将为所有在数组中元素的工作，无论什么原因，你只需要name，city和01。，然后更换return有：

return $v['name'].'-'.$v['city'].'-'.$v['street'];
