PHPerKaigi 2026
Overview
A tech conference styled as a "festival by PHPers, for PHPers." Since its 2018 debut it has built a devoted following through its emphasis on attendee interaction — code battles, unconferences, and hallway conversations alongside talks. The 2026 edition ran three days, March 20-22, in Nakano as an offline-online hybrid.

Voices
A dense three days where hallway and after-party discussions were as valuable as the sessions themselves.
An exceptionally moving event that prompts reflection on technology, PHP, and what it means to be an engineer.
Even as a first-timer debuting in the Rookies LT track, the community's welcoming atmosphere pushed me forward.
Helped run reception while picking up insights on layering and test design (from Munakata's report, in Japanese)
Spoke on building a PHP APM with the OpenTelemetry SDK, deepening their observability skills (from Futoshi Endo's report, in Japanese)
Attended as both speaker and listener, bringing performance-tuning and CI-speedup insights back to daily work and finding the networking at the after-party energizing (from P-yama of GO Inc.'s report, in Japanese)
