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?code5=";
 /**
 * 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'];
 }
 /**

 * @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);
 }
 $stock_url = self::STOCK_URL."?stockid=".$stockid;
 $result = self::httpGet( $stock_url , true );
 if( $result['errNum'] != 0 ){
 throw new Exception($result['errMsg'], 1);
 return;
 }
 return $result['retData'];
 }
 /**

 * @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];
 }
 /**

 * @param param string 参数

 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');
