mysqli_stmt :: bind_param（）类型定义字符串中的元素数与数字不匹配

Question

我在使用mysqli_stmt :: bind_param（）时遇到问题。有人能帮我吗？  警告：mysqli_stmt :: bind_param（）[mysqli-stmt.bind-param]：类型定义字符串中的元素数与绑定变量数不匹配...

我是php的初学者。感谢

 public function init($cards,$table,$seats)
 {
$operation = $this->operation($table, $seats);
return $this->insertCards($cards,$operation,count($cards));

  }     
public function operation($table, $seats)
{
  $operation = "insert into ".$table."(";
  $values = "(";
  for($i = 0; $i<count($seats);$i++)
  {
    $operation .= " cardsSeat".$seats[$i].",";
    $values .= "?,";
  }
  $values .= "?,?,?)";
  $operation .= " flop, turn, river) values ".$values;

  return $operation;        

}


    public function insertCards($cards, $operation, $x)
    {

        $insertCards = $this->spojenie->prepare($operation);
        $refArray = array();
        foreach($cards as $key => $value) $refArray[$key] = &$cards[$key];
        call_user_func_array(array($insertCards, 'bind_param'), $refArray);



        $insertCards->execute();
        return true;

    }

• 字符串类型（“sss ...”）;

公共功能insertCards（$ cards，$ operation，$ x）         {

        $types = "";
        foreach($cards as $value)
            $types .= "s";
        $cards = array_merge(array($types),$cards);
        $insertCards = $this->spojenie->prepare($operation);
        $refArray = array();
        foreach($cards as $key => $value) $refArray[$key] = &$cards[$key];
        call_user_func_array(array($insertCards, 'bind_param'), $refArray);



        $insertCards->execute();
        return true;
    }
