股票信息查询功能我们是需要抓取第三方的数据,然后我们再把这些数据进行分析组成自己想要的,下面我们来看一个php 股票信息查询类.

今天一个二逼朋友让我帮忙写个股票查询的类,来集成到微信中,所以花了一点时间写了一个不完整的,哈哈,如果有想玩的人,可以继续提交代码,让它变得完善起来！！

GitHub 地址:github.com/widuu/stock,代码如下:

1. class stock{
2. /**
3. * 股票数据接口
4. */
5. const STOCK_URL = "http://apis.baidu.com/apistore/stockservice/stock";
6. /**
7. * 通过拼音或者汉字获取股票代码
8. */
9. const SOCKET_SUGGEST = "http://cjhq.baidu.com/suggest?code5=";
10. /**
11. * 单态实例
12. */
13. private static $instance;
14. /**
15. * API 密钥
16. */
17. private static $apikey;
18. /**
19. * 实例化类和指定API KEY
20. * @param apikey string
21. * @return instance object
22. */
23. public static function getInstance($apikey){
24. if( self::$instance == NULL ){
25. self::$instance = new self;
26. self::$apikey = $apikey;
27. }
28. return self::$instance;
29. }
30. /**

37. return $result['name'];
38. }
