Thanks for the summary! For the record, FrankenPHP and NGINX Unit use threads, not forks (and recommend ZTS PHP builds). And as far as I understand, Swoole etc use a reactor pattern and non-blocking IOs, not threads. Also Symfony Runtime isn’t an engine but a library with adapters for FrankenPHP, RoadRunner, Bref etc. The main SAPI using libphp is the embed SAPI, but some non-core SAPIs including FrankenPHP, NGINX Unit and uWSGI use libphp with their own SAPIs. The confusing part is that you need to enable the embed SAPI through the configure options to build libphp, even if the embed SAPI itself isn’t used.
