Top 23 PHP Async Projects
-
For Laravel/PHP backends, use Ratchet or delegate the WebSocket relay to a small Node.js sidecar. PHP's blocking I/O model makes it genuinely ill-suited for sustained bidirectional streaming — don't fight it. I've seen teams spend weeks trying to make it work before giving up and spinning up a tiny Node service that took an afternoon.

If you want the branches to actually run at the same time, you need the AsyncExecutor, which is built on Amp:

The online playground is running a very old version (~0.20.0 from months ago, which did not even have a static analyzer) and gives a poor impression of the current tool. That's on me to fix or take down.
The issue you saw with built-in classes like `RuntimeException` was absolutely a bug in those early alpha versions, but it has been fixed for a long time now. The analyzer has matured a lot since then.
The current beta is stable enough to be the sole static analysis tool for a couple of extremely well-typed projects:

Project mention: PHP async: event loop, Fibers and the limits of single-threading | dev.to | 2026-05-13The database case is more nuanced. PDO, PHP's default driver, is entirely blocking: a SQL query blocks the thread until the response. With ReactPHP or Amp, using PDO inside a Fiber cancels all the benefit — the Fiber blocks like classic synchronous code. You need native async drivers: amphp/mysql or amphp/postgres for PostgreSQL. Adoption of these drivers is still limited, which makes the Amp + PostgreSQL stack less natural than its Node.js equivalent.
