如何向数组中的特定键添加更多元素？

我正在尝试将xml节点转换为数组，我在父match节点内有3个分离的节点，因此我需要将所有它们都转换为数组。

当我尝试此代码

foreach($lineup->away->player as $player){
    $awaysquad .= $player->attributes()->name . '; ';
    $matcharr['name'] = (string)$player->attributes()->name;
    $matcharr['number'] = (int)$player->attributes()->number;
    $matcharr['playerid'] = (int)$player->attributes()->id;

    $yellowcount = count(explode(" ",$player->attributes()->booking));
    if(substr_count($player->attributes()->booking,"YC") == 1){
      $matcharr['yellow'] = (int)$player->attributes()->id;
    }
    elseif((substr_count($player->attributes()->booking,"RC")==1) 
    or ($yellowcount == 3)){
      $matcharr['red'] = (int)$player->attributes()->id;
    }
}

并通过以下方式将此匹配器称为：

print_r($matcharr);

每个索引/数组只有最后一个元素，我想从阵容标签中获取所有玩家。

因此，print_r将输出以下内容：

数组（[目标] => 2456166 [名称] =>路易斯·里尔[数字] => 9 [玩家编号] => 2474225 [黄色] => 2486288 [subin] => 2353344 [subout] => 0 [分钟] => NA）

每场比赛的标签，但我需要为每场比赛获得22名球员。

这里是更详细的代码：

foreach($week->match as $match){
                              $matcharr = array();  
                              //var_dump($match);
                              $fixid = 0;
                              if($match->attributes()->id == 0 || $match->attributes()->id == ''){
                                  if($match->attributes()->alternate_id == 0 || $match->attributes()->id == ''){
                                      $fixid = $match->attributes()->alternate_id_2;
                                  }
                                  else{
                                      $fixid = $match->attributes()->alternate_id;
                                  }
                              }
                              else{
                                  $fixid = $match->attributes()->id;
                              }
