如何添加更多元素到數組中的特定鍵？

Question

我正在嘗試將xml節點轉換為數組，我在父匹配節點內有3個分離的節點，因此我需要將所有它們都轉換為數組。

當我嘗試此代碼

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;
    }
}

並通過以下方式將此匹配器稱為：

print_r($matcharr);

每個索引/數組只有一個元素，我想從陣容標簽中獲取所有玩家。

因此，print_r將輸出以下內容：

數組（[目標] => 2456166 [名稱] =>路易斯·里爾[數字] => 9 [玩家編號] => 2474225 [黃色] => 2486288 [subin] => 2353344 [subout] => 0 [分鍾] => NA）

每個比賽標簽，但我需要為每個比賽獲得22名球員。

這里是更詳細的代碼：

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;
                              }
                              $dbdate = date('Y-m-d',strtotime($match->attributes()->date));
                              $dbtime = date('H:i:s', strtotime($match->attributes()->time));
                              //if($dbdate == date('Y-m-d')){
                              echo $dbdate . ' ' . date("Y-m-d");
                              $datetime = date('Y-m-d H:i:s',strtotime($dbdate . $dbtime));
                              $fcountry = $this->filterCountries($results->attributes()->country);  

                              $stadium = $match->attributes()->venue;
                              $city = $match->attributes()->venue_city;

Answer 1

在將其存儲在數組中之前，添加一些計數器變量，如下所示

$element_count = 0;//Counter variable
foreach ($lineup->away->player as $player) {
    $awaysquad .= $player->attributes()->name . '; ';
    $matcharr[$element_count]['name'] = (string)$player->attributes()->name;
    $matcharr[$element_count]['number'] = (int)$player->attributes()->number;
    $matcharr[$element_count]['playerid'] = (int)$player->attributes()->id;

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