PHP排序复杂的多维数组

Question

我一直在努力尝试通过“user_likes”和“created_time”在PHP中排序这个数组我已经看了一些关于Stackoverflow的例子，但无法弄清楚正确的语法。我想要命令从最“user_likes”，然后“created_time”不知道是否有可能。我一直在尝试与array_multisort没有运气。

 Array

           [isFav] => 0 
          ) 

        ) 

      ) 

Answer 1

其中$结果是上面的阵列，尝试

usort($results, function($a, $b){ 
    //check case for same number of user likes 
    if ($a['user_likes']['user_likes'] == $b['user_likes']['user_likes']){ 
     if (strtotime($a['taskuser']['created_time']) == strtotime($b['taskuser']['created_time'])){ 
      return 0; 
     } else if (strtotime($a['taskuser']['created_time']) < strtotime($b['taskuser']['created_time'])){ 
      return 1; 
     } else { 
      return -1; 
     } 

    } else if ($a['user_likes']['user_likes'] < $b['user_likes']['user_likes']){ 
     return 1; 
    } else { 
     return -1; 
    } 
}); 

Answer 2

你想要usort。有回调比较user_likes，然后created_time。
