Php curl-based stock information query instance

This article mainly introduces the curl-based php stock information query class, and analyzes the related operation skills of php using curl to call the API interface to realize the stock information query function in the form of a complete instance, you can refer to the example in this article to describe the stock information query class implemented by php based on curl. We will share this with you for your reference. The details are as follows:

We need to capture third-party data for the stock information query function, and then analyze the data to make up what we want. next we will look at a php stock information query class.

Today, a friend of mine asked me to help write a stock query class to integrate it into the middle, so I spent a little time writing an incomplete one. haha, if someone wants to play, you can continue to submit code to make it perfect !!

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

Class stock {/*** stock data interface */const STOCK_URL =" http://apis.baidu.com/apistore/stockservice/stock ";/*** Get the stock code through pinyin or Chinese characters */const SOCKET_SUGGEST =" http://cjhq.baidu.com/suggest?code5= ";/*** Single-state instance */private static $ instance;/*** API key */private static $ apikey; /*** instantiate the class and specify the 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 ;} /*** get the stock name * @ param stockid string * @ return stockName string */public static functio N getName ($ stockid) {$ result = self: getSingleStock ($ stockid); return $ result ['name'];} /*** get the last update time * @ param stockid string * @ return time string */public static function getTime ($ stockid) {$ result = self :: getSingleStock ($ stockid); return $ result ['Date']. $ result ['Time'];} /*** get the Kline chart address * @ 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.
