PHP based on curl implementation of stock information query class instance

This paper describes the stock information query class based on curl implemented by PHP. Share to everyone for your reference, as follows:

Stock information query function we need to crawl the data of the third party, and then we analyze the data to compose what we want, let's look at a PHP stock information query class.

Today a two-cornered friend let me help write a stock query class, to integrate into the, so spent a little time to write an incomplete, haha, if you want to play the person, you can continue to submit code, let it become perfect up!!

GitHub Address: Github.com/widuu/stock, the code is as follows:
