PHP可捕獲的致命錯誤：參數1傳遞給必須是類型數組，null給出，在行208中調用並定義

Question

我一直面臨一個奇怪的問題，我不能得到解決。長話短說，當我參加一個我正在創建的遊戲的迷你遊戲時，它會很好！但是當我退出迷你遊戲的時候，它應該把我送回房間，但是卻給了我一個錯誤。

這是錯誤：

PHP Catchable fatal error: Argument 1 passed to Sweater\Server::leaveTable() must be of the type array, string given, called in /usr/share/nginx/Sweater/Sweater/GameHandler.php on line 208 and defined in /usr/share/nginx/Sweater/Sweater/GameHandler.php on line 184

我做了一些研究提出這個問題之前試過，我遇到了解決方案，但遺憾的是他們沒有工作。

GameHandler.php handleLeaveTable：

function handleLeaveTable(Array $arrData, Client $objClient) { 
     $intPlayer = $arrData[0]; 
     $this->leaveTable($intPlayer); // Line 208 
    } 

GameHandler.php leaveTable：

function leaveTable(Array $arrData, Client $objClient) { // Line 184 
      $intPlayer = $arrData[4]; 
      $tableId = $intPlayer->tableId; 
      if($tableId !== null) { 
       $seatId = array_search($intPlayer, $this->playersByTableId[$tableId]); 
       $opponentSeatId = $seatId == 0 ? 1 : 0; 
       if(isset($this->playersByTableId[$tableId][$opponentSeatId])) { 
        $this->playersByTableId[$tableId][$opponentSeatId]->addCoins(10); 
        } 
        unset($this->playersByTableId[$tableId][$seatId]); 
        unset($this->tablePopulationById[$tableId][$intPlayer->$strUsername]); 
        $objClient->sendXt('ut', $objClient->getIntRoom(), $tableId, $seatId); 
        $intPlayer->tableId = null; 
        if(count($this->playersByTableId[$tableId]) == 0) { 
        $this->playersByTableId[$tableId] = array(); 
        $this->gamesByTableId[$tableId] = null; 
       } 
     } 
    } 

問題是什麼嗎？我檢查了一切，無法找到解決方案。

編輯，什麼$ arrData是：

function decodeData($strData){ 
     $arrData = simplexml_load_string($strData, 'SimpleXMLElement', LIBXML_NOCDATA); 
     if($arrData === false){ 
      throw new Exceptions\HandlingException('Unable to parse client\'s XML data'); 
     } 
     $arrData = json_decode(json_encode((array)$arrData), true); 
     return $arrData; 
    } 

function handleData($strData, $objClient){ 
     $arrData = explode($this->arrConfig['Packets']['Delimiter'], $strData); 
     array_pop($arrData); 
     foreach($arrData as $strData){ 
      Silk\Logger::Log('Received data: ' . $strData); 
      $strSubstring = substr($strData, 0, 1); 
      $blnPossibleXML = $strSubstring == '<' ? true : false; 
      $blnPossibleGame = $strSubstring == '%' ? true : false; 
      if($blnPossibleXML === false && $blnPossibleGame === false){ 
       throw new Exceptions\HandlingException('Bad client detected!'); 
      } 
      $blnPossibleXML ? 
      $this->handleXMLData($strData, $objClient): 
      $this->handleGameData($strData, $objClient); 
     } 
     unset($arrData); 
    } 

Answer 1

PHP Catchable fatal error: Argument 1 passed to Sweater\Server::leaveTable() must be of the type array, string given, called in /usr/share/nginx/Sweater/Sweater/GameHandler.php on line 208 and defined in /usr/share/nginx/Sweater/Sweater/GameHandler.php on line 184

從$arrData你把它串

$intPlayer = $arrData[0]; 
$this->leaveTable($intPlayer); // Line 208 

的第一個元素在GameHandler.php handleLeaveTable:

你拿第一元素形成一個數組

然後在GameHandler.php leaveTable:

您試圖訪問該元素作爲一個數組，然後採取
