如何搜索多维数组以返回多个键 [英] How to search a multidimensional array to return multiple keys

问题描述

我有一个用php编写的多维数组，其中包含一个数组数组。我已经阅读了很多有关如何搜索此内容的信息，但似乎大多数解决方案还是：

I've got a multidimensional array written in php that holds an array of arrays. I've read a lot about how to search this, but it seems most solutions either:

A。要求您具有唯一的键值，例如产品ID

A. require you have unique values for the keys, such as a product id

或

B。我对在数组中返回多个结果感到满意

B. are satisfied with returning multiple results in an array

我要搜索的数组给出了舍入编号（这是数组的数组编号最高/第一级数组）和玩家名称（将是关键玩家1或玩家2的值）。

I am looking to search the array given the round number (which is the array number of the highest/first level array), and a player name (which will be the value of either the key player 1 or player 2).

该数组如下所示：

Array ( 
            [0] => Array ( )
            [8] => Array ( 
                    [1] => Array ( 
                                  [Match] => 1 
                                  [Player1seed] => (Q) 
                                  [Player1name] => Mahut 
                                  [Player2seed] => (2) 
                                  [Player2name] => Goffin 
                                  [Matchscore] => 7-6(1), 6-1 
                                  [Round] => Finals 
                                  ) 
                           ) 

            [7] => Array   ( 
                   [1] => Array (
                                  [Match] => 1 
                                  [Player1seed] => (2) 
                                  [Player1name] => Goffin 
                                  [Player2seed] => 
                                  [Player2name] => Muller 
                                  [Matchscore] => 7-6(4), 6-4 
                                  [Round] => Semi-Finals 
                               ) 
                   [2] => Array
                    ( 
                                  [Match] => 2 
                                  [Player1seed] => (Q) 
                                  [Player1name] => Mahut 
                                  [Player2seed] => (WC) 
                                  [Player2name] => Haase 
                                  [Matchscore] => 5-7, 6-3, 6-4 
                                  [Round] => Semi-Finals 
                   ) 
             ) 

等。

本质上，我需要能够专门搜索一个子集，例如 array [7] ，并返回包含玩家1或玩家2作为名称的结果，例如高芬。

Essentially, I need to be able to search specifically one subset such as array[7] and be returned the results that contains either player1 or player2 as a name, say Goffin.

但我不希望它返回其他锦标赛回合的结果，例如 array [8] 或 array [ 6] 其中一位是高芬。

But I don't want it to return results from other tournament rounds such as array[8] or array[6] where either player is Goffin.

我似乎在任何地方都找不到这种解决方案。我设置阵列不正确吗？还是希望从较少的数据集中获得数据库功能？

I can't seem to find this solution anywhere. Am I setting up my array incorrectly? Or expecting database functions from a lesser data set?

任何帮助将不胜感激。

推荐答案

这并不是我想要解决的问题的确切方法，但是在标识了特定的轮数之后，我可以通过运行循环来获得想要的结果：

It's not exactly the way I wanted to solve the problem, but I was able to get the results I wanted by running a loop after identifying the specific round number:

$r = $roundnumber;

        foreach( $matchesarray[$r] AS $key=>$data ){

                $winnerseed=$data['Player1seed'];
                $winnername=$data['Player1name'];
                $loserseed=$data['Player2seed'];
                $losername=$data['Player2name'];
                $matchurl=$data['Matchurl'];
                $score=$data['Matchscore'];

                if ($p1name == $winnername || $p2name == $losername){
                    $winner=$p1;
                }
                else if ($p2name == $winnername || $p1name == $losername){
                    $winner=$p2;
                }

        }
