Example of stock information query class implemented by PHP based on curl

The example in this article describes the stock information query class implemented by PHP based on curl. Share it with everyone for your reference, the details are as follows:

For the stock information query function, we need to capture third-party data, and then we analyze the data to form what we want. Next, let’s look at a PHP stock information query class .

Today, a sexy friend asked me to help write a stock query class to integrate into WeChat, so I spent some time writing an incomplete one, haha. If anyone wants to play, you can continue to submit the code. Make it perfect! !

GitHub address: github.com/widuu/stock, the code is as follows:

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'];
  }
  /**
   * 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);
    }
    $stock_url = self::STOCK_URL."?stockid=".$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');

I hope this article will be helpful to everyone in PHP programming.
