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.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
