First of all, a statement: I made this PHP version of Fetion as a black box research based on the Fetion communication protocol. It is purely for the purpose of learning and hobby research. Commercial use is not allowed! The source code includes fetionserver.php, which I still provide for free, and a-client.php, which I previously provided for testing. There are two files in the compressed package, vs_fetion (socket version).class.php and vs_fetion.class.php, depending on the actual situation. The protocol used is the same, but the PHP extension used is different. Generally speaking, the compatibility of vs_fetion.class.php is better.
OK, without further ado, let’s serve!

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AMDependency 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: Identifying and Fixing BottlenecksMay 11, 2025 am 12:13 AMPHP 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.
