PSR 7 HTTP Messages In the Wild
summary
PSR-7 defines immutable HTTP message interfaces and a mutable Stream exception, and shows concrete interoperability: Guzzle v6 plus zend-diactoros and php-http adapters implement the interfaces, letting a PSR-7 request be proxied to the GitHub API; demos show async promises and middleware, four concurrent user profile requests finish in ~400 ms where sequential calls take >1 s, and a ServerRequestFactory/Emitter convert globals to PSR-7 and back for existing apps.
