深圳通余额查询的API

深圳通余额查询的API，可以通过深圳通号码查询到余额及卡有效期等信息。 用到Domxpath和Curl两方面的知识。 源码已托管到github，另外要加载个类：myclass 项目地址：https://github.com/skiy/dev 演示：http://api.oupag.com/dev/api/shenzhentong.php?cardn

curls("http://query.shenzhentong.com:8080/sztnet/qryCard.do", false, $post_cardno);
    //直接GET方式
    $page = $data->curls("http://query.shenzhentong.com:8080/sztnet/qryCard.do?cardno={$cardno}");
    $page = $data->pageToDom($page, "GBK");

    $tr = $page->query("//table[@class='tableact']/tr/td");

    function getTextContent($m_query, $m_id) {
        $myTXT = str_replace("：", "", $m_query->item($m_id)->textContent);
        return $myTXT;
    }

    //截止时间内余额
    preg_match("/截止到([^\)]*)/", getTextContent($tr, 2), $expires);

    $results = array(
        "card_number" =>  (int) getTextContent($tr, 1),
        "card_balance" =>  getTextContent($tr, 3),
        "balance_time" => $expires[1],
        "card_validity" =>  getTextContent($tr, 5),
        "current_time" => date("Y-m-d H:i:s", time()));

    echo json_encode($results);

?>
