第一种

protected function isCreditNo($vStr)
    { 
      $vCity = array(
        '11','12','13','14','15','21','22',
        '23','31','32','33','34','35','36',
        '37','41','42','43','44','45','46',
        '50','51','52','53','54','61','62',
        '63','64','65','71','81','82','91'
      );
      if (!preg_match('/^([\d]{17}[xX\d]|[\d]{15})$/', $vStr)) return 0;
      if (!in_array(substr($vStr, 0, 2), $vCity)) return 0;
      $vStr = preg_replace('/[xX]$/i', 'a', $vStr);
      $vLength = strlen($vStr);
      if ($vLength == 18) { 
        $vBirthday = substr($vStr, 6, 4) . '-' . substr($vStr, 10, 2) . '-' . substr($vStr, 12, 2);
      } else { 
        $vBirthday = '19' . substr($vStr, 6, 2) . '-' . substr($vStr, 8, 2) . '-' . substr($vStr, 10, 2);
      }
      if (date('Y-m-d', strtotime($vBirthday)) != $vBirthday) return 0;
      if ($vLength == 18) { 
        $vSum = 0;
        for ($i = 17 ; $i >= 0 ; $i--) { 
          $vSubStr = substr($vStr, 17 - $i, 1);
          $vSum += (pow(2, $i) % 11) * (($vSubStr == 'a') ? 10 : intval($vSubStr , 11));
        }
        if($vSum % 11 != 1) return 0;
      }
      return 1;
    }
