本文实例讲述了php基于curl实现的股票信息查询类。分享给大家供大家参考，具体如下：

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:

class stock{ /** * 股票数据接口 */ const STOCK_URL = "http://apis.baidu.com/apistore/stockservice/stock"; /** * 通过拼音或者汉字获取股票代码 */ const SOCKET_SUGGEST = "http://cjhq.baidu.com/suggest"; /** * 单态实例 */ private static $instance; /** * API 密钥 */ private static $apikey; /** * 实例化类和指定API KEY * @param apikey string * @return instance object */ public static function getInstance($apikey){ if( self::$instance == NULL ){ self::$instance = new self; self::$apikey = $apikey; } return self::$instance; } /** * 获取股票名称 * @param stockid string * @return stockName string */ public static function getName($stockid){ $result = self::getSingleStock($stockid); return $result['name']; } /** * 获取最后更新时间 * @param stockid string * @return time string */ public static function getTime($stockid){ $result = self::getSingleStock($stockid); return $result['date'].$result['time']; } /** * 获取K线图地址 * @param stockid string * @param date string min/day/week/mouth * @return imageUrl string */ public static function getKline($stockid,$date='min'){ $result = self::getSingleStock($stockid); return $result['klinegraph'][$date.'url']; } /** * 抓取整只股票的数据 * @param stockid string * @return stock infomation array */ public static function getSingleStock($stockid){ $type = preg_match('/(d+){6}/is', $stockid); if ( $type == 0 ){ $stockid = self::getStockId($stockid); } $stock_url = self::STOCK_URL."".$stockid; $result = self::httpGet( $stock_url , true ); if( $result['errNum'] != 0 ){ throw new Exception($result['errMsg'], 1); return; } return $result['retData']; } /** * 输入拼音或者汉字来获取股票代码 * @param name string * @return stockid string */ private static function getStockId($name){ $result = self::httpGet( self::SOCKET_SUGGEST.urlencode(iconv('utf-8', 'GBK', $name)),false ); if (emptyempty($result)){ throw new Exception("stock name not exists", 2); return; } $stockid = $result['Result'][0]['code']; $stock = explode('.', $stockid); return $stock[1].$stock[0]; } /** * GET获取方法 * @param param string 参数 * @author widuu */ private static function httpGet($url,$header=false) { $curlHandle = curl_init(); curl_setopt( $curlHandle , CURLOPT_URL, $url ); if( $header ){ curl_setopt( $curlHandle , CURLOPT_HTTPHEADER , array('apikey:'.self::$apikey)); } curl_setopt( $curlHandle , CURLOPT_RETURNTRANSFER, 1 ); curl_setopt( $curlHandle , CURLOPT_SSL_VERIFYPEER, false); curl_setopt( $curlHandle , CURLOPT_SSL_VERIFYHOST, false); curl_setopt( $curlHandle , CURLOPT_TIMEOUT, 10 ); $content = curl_exec( $curlHandle ); curl_close( $curlHandle ); return $header ? json_decode($content,true) :json_decode(iconv('GBK','utf-8',trim($content)),true); } } //测试代码 stock::getInstance("5040bcbfebb0a4cffc7be278723255aa"); print_r(stock::getSingleStock('sh601000')); echo stock::getKline('紫金矿业');

希望本文所述对大家PHP程序设计有所帮助。
