Key Insights from PHPConChina 2020: QUIC, HTTP/3, Micro‑services, and Swow for PHP

The annual China PHP Developers Summit (PHPConChina 2020) gathered top experts to discuss cutting‑edge topics and best practices in PHP development.

Speaker Han Tianfeng, a prominent PHP architect, explained that the 50‑year‑old TCP/IP stack struggles with modern high‑bandwidth and high‑latency networks, and that QUIC (Quick UDP Internet Connections) combined with HTTP/3 can dramatically reduce round‑trip times, especially in weak network conditions.

He noted that PHP applications can adopt QUIC and HTTP/3 without code changes by enabling support at the gateway, SLB, or HAProxy layer.

Regarding micro‑services, Han compared PHP's ecosystem to Java’s Spring Cloud and Golang’s frameworks, acknowledging that PHP frameworks like Hyperf, Swoft, and EasySwoole are still maturing. He advocated using ServiceMesh (Istio + Envoy on Kubernetes) to offload service‑governance to sidecars, allowing existing PHP codebases to benefit from advanced service‑mesh capabilities.

He concluded with career advice: leverage existing tools, maintain a learning mindset, and prioritize system stability.

Speaker Jing Luo, an open‑source enthusiast with extensive backend experience, emphasized the importance of continuous learning, systematic knowledge retention, and aligning learning outcomes with business needs.

Speaker Chen Caoqiao (Twosee), core author of Swoole, described the rapid maturation of the Swoole project and introduced the new PHP network engine Swow, which aims to implement most of its core in PHP while keeping a minimal C footprint.

Swow’s key features include fine‑grained coroutine control (inspection, debugging, interruption), precise memory management via a Buffer module, modern object‑oriented design that boosts developer productivity, and broad compatibility across Linux, Windows, CLI, FPM, and other SAPIs.

He cautioned that coroutines are not a silver bullet, and that PHP’s inherent development efficiency remains essential for Swow’s success.

The conference concluded with a commitment from the Xueersi Net School technical team to continue collaborating and advancing PHP technology.
