Async PHP with Coroutines: Building Scalable Applications
summary
Shows that PHP moves from blocking request–per–process to real async: demos use Swoole coroutines and native PHP fibers, convert three sequential API calls into parallel ones and report 4–8x faster in examples. Claims at modest hardware reach ~10,000 requests per second on one server and ~2 MB per 1,000 coroutines memory. Builds include HTTP/WebSocket servers, channels and shared globals and the demos claim they work and simplify IO‑bound scaling for Appwrite‑style services.
