Qandidate Feature Flagging Library – Qandidate Labs

  • “At we developed a feature toggle library that allows us to easily work with feature toggles. The goal was to minimize the barrier to use the toggles and be able to flip toggles at runtime, so we added an API with a Redis backend and a graphical user interface to flip the switches.”

Rollout (for PHP) – Richard Fullmer

PHP Feature Flags – Jay Fienberg

  • “A simple PHP class for setting feature flags via HTTP cookie, URI query parameter or IP address. This is a PHP class that reads feature flags in URL query strings, browser cookies, and/or client IP address. These are only “on” flags–they do not represent values or states beyond “on”. The idea is: when a flag is absent, it is off, When a flag is present, it is on. The function then allows you to test for specific flags being present / on, using the above $ff->hasFlag(‘your-flag-name’) syntax. Note that this library doesn’t help you set flags per se–it just reads them.”
