With the popularity of WeChat, the WeChat public platform has become the next target for many developers. The author himself is not so attracted to this new thing. But recently, a friend helped develop a score query function on the WeChat public platform. So I did some research in my spare time.

The main implementation steps are to simulate logging into the target website through PHP's CURL technology, obtain the user's performance information through the logged-in user, use regular expressions to capture and store the data, and use HTML technology to reconstruct the data. Do the typesetting.

The function of the WeChat public platform is to query scores through browsing. The overall technical implementation lies in PHP's CURL technology. Let’s just find a file and get the results. The specific code is as follows.
