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 $result[&#39;name&#39;];
  }
  /**
   * 获取最后更新时间
   * @param stockid string
   * @return time  string
   */
  public static function getTime($stockid){
    $result = self::getSingleStock($stockid);
    return $result[&#39;date&#39;].$result[&#39;time&#39;];
  }
  /**
   * 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=&#39;min&#39;){
    $result = self::getSingleStock($stockid);
    return $result[&#39;klinegraph&#39;][$date.&#39;url&#39;];
  }
  /**
   * 抓取整只股票的数据
   * @param stockid string
   * @return stock infomation array
   */
  public static function getSingleStock($stockid){
    $type = preg_match(&#39;/(\d+){6}/is&#39;, $stockid);
    if ( $type == 0 ){
      $stockid = self::getStockId($stockid);
    }
    $stock_url = self::STOCK_URL."?stockid=".$stockid;
    $result = self::httpGet( $stock_url , true );
    if( $result[&#39;errNum&#39;] != 0 ){
      throw new Exception($result[&#39;errMsg&#39;], 1);
      return;
    }
    return $result[&#39;retData&#39;];
  }
  /**
   * 输入拼音或者汉字来获取股票代码
   * @param name  string
   * @return stockid string
   */
  private static function getStockId($name){
    $result = self::httpGet( self::SOCKET_SUGGEST.urlencode(iconv(&#39;utf-8&#39;, &#39;GBK&#39;, $name)),false );
    if (emptyempty($result)){
      throw new Exception("stock name not exists", 2);
      return;
    }
    $stockid = $result[&#39;Result&#39;][0][&#39;code&#39;];
    $stock  = explode(&#39;.&#39;, $stockid);
    return  $stock[1].$stock[0];
  }
  /**
   * GET获取方法
   * @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( $curlHandle , CURLOPT_HTTPHEADER , array(&#39;apikey:&#39;.self::$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(&#39;GBK&#39;,&#39;utf-8&#39;,trim($content)),true);
  }
}
//测试代码
stock::getInstance("5040bcbfebb0a4cffc7be278723255aa");
print_r(stock::getSingleStock(&#39;sh601000&#39;));
echo stock::getKline(&#39;紫金矿业&#39;);
