Php curl-based Stock Information Query Class instance, curl Information Query

This example describes 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 !!
