Introducing Fend PHP Framework: Design Principles, Features, Performance Benchmarks, and Installation Guide

好未来 (TAL) is a technology‑driven education company that has developed a high‑performance PHP framework called Fend , which has been open‑sourced and is now used by more than 30 internal teams.

The framework follows a "big middle‑platform, small front‑end" strategy, emphasizing unified infrastructure, open‑source sharing, and rapid business implementation.

Design direction focuses on simplicity, a single‑layer kernel, high cohesion, continuous accumulation of large‑scale internet experience, and an open‑source mindset. 简单实用 ：快速上手，功能一步到位，降低复杂度。 单层内核 ：不继承封装，保持实现简洁。 内聚归类 ：高度集中功能，降低底层关注度。 持续积累 ：持续沉淀线上运营经验。 内核设计 ：高内聚、简单内核，留出业务自封装空间。 开源心态 ：开放源码，严格代码审核。

Feature highlights include seamless switching between Swoole and FPM engines, Composer PSR‑4 autoload, debug mode via wxdebug=1, coroutine‑friendly variable handling, gray‑shadow database for load testing, high‑speed map routing, trace‑log design for big‑data analysis, and exception handling with throw new Exception.

Performance testing on a KVM CentOS 7.6 VM (4‑core Xeon 2.2 GHz, 12 GB RAM) shows:

FPM QPS ≈ 5331 (hello‑only 10k, Composer autoload 7k, trace logging 6k, framework echo 5k).

Swoole 1.10.x achieves higher QPS (see attached chart).

Release versions :

Tag 1.2.x – supports FPM/Swoole 1.10.x smooth switching.

Tag 1.3.x – supports FPM/Swoole 4.5.x coroutine switching (still adjusting).

Installation instructions for the 1.2.x version are provided, including engine start commands for both FPM and Swoole, with example nginx.conf configuration and URLs to access the running service.

The project’s open‑source repository is https://github.com/tal-tech/fend , with an issue tracker at https://github.com/tal-tech/fend/issues . Over a hundred senior engineers have starred the project, and contributors are invited to submit PRs, join the WeChat group, and follow the co‑construction rules that prioritize performance, practicality, and simplicity.
