版本2.1.0 oci8_result.php一个明显的bug

zhy

public function num_rows()
{
  if ($this->num_rows === 0 && count($this->result_array()) > 0)
  {
   $this->num_rows = count($this->result_array());
   @oci_execute($this->stmt_id);
   if ($this->curs_id)
   {
    @oci_execute($this->curs_id);
   }
  }
  return $rowcount;
}

oci8_result.php版本2.1.0
$rowcount没定义，这么明显的bug也没测出来？
