补充 银行卡信息数据库
网上找了一番，发现有网站提供了这种服务，如下
http://www.yinhangkadata.com/
http://www.yinhangkahao.com/
这个查询都做了IP的限制，一个IP只能查询几次。突然想到了这种方式可能存在的bug，可以任意伪造来源IP。这个漏洞真是喜闻乐见啊。
调用方法：
$BankCard = new BankCard();
$cardInfo = $BankCard->query(‘6222021207020181225’);
返回结果：
array(5) {
[“bank_name”]=>
string(12) “工商银行”
[“card_name”]=>
string(10) “E时代卡”
[“card_type”]=>
string(9) “借记卡”
[“province”]=>
string(9) “浙江省”
[“city”]=>
string(6) “台州”
}
以下是代码实现：
查询类：
namespace Common\Util;
use Org\Net\HttpClient;
class BankCard {
private $target;
private $error;
public function getError()
{
return $this->error;

public function __construct()

}
public function query($card){
$httpClient = new HttpClient();
$result = $httpClient->get($this->target.'?card='.$card,array('headers'=>array('X-FORWARDED-FOR:'.$this->getId(),'timeout:5')));
trace($result);
$result = str_replace(array("\r\n", "\r", "\n","(", ")"), "", $result);
$data =array();
if(preg_match('/<p>(.{2,50})(\d{8}) -- (.*?) -- (.*?)<\/p>/i', $result, $matches)) {

}
if(preg_match('/<font color=red>(.*?) -- (.*?)<\/font>/i', $result, $matches)) {

}
if(count($data)>0){
return $data;

return false;
}
