Improving Application Performance with ReactPHP
summary
Explains how ReactPHP turns PHP into an event loop system using promises and streams, showing a concrete rewrite of three sequential HTTP requests into concurrent Browser client calls that wait only for the slowest response. Demonstrates timers, stream chunk processing, and async DB/file adapters (avoid PDO and file_get_contents). Notes pitfalls: any blocking call freezes the loop, long-running handlers and memory cleanup matter. Cites DriftPHP built on ReactPHP and a production crypto-exchange migration that measurably improves throughput.
