 La programmation multithreadée en PHP est un véritable casse tête, en effet il n’existe pas à l’heure d’aujourd’hui de véritable moyen de faire du multithread en PHP 5. Et puis cela peut poser des problèmes de partage des ressources, je pense notamment à l'accès aux base de données.
+  * Php8 fibers
+    * It is important the concurrent execution does not mean simultaneous execution. The Fiber and the main execution flow does not happen at the same time. It is up to the main execution flow to start a Fiber, and when it starts, the Fiber is executed exclusively. The main thread cannot observe, terminate, or suspend a Fiber while the Fiber is being executed.

   * https://revolt.run/
     * Revolt is a rock-solid event loop for concurrent PHP applications. The usual PHP application spends most of its time waiting for I/O. While PHP is single threaded, cooperative multitasking can be used to allow for concurrency by using the waiting time to do different things.
   * https://reactphp.org/
     * ReactPHP is a low-level library for event-driven programming in PHP.
+  * https://amphp.org/
+    * AMPHP provides higher-level libraries using non-blocking I/O under the hood. Fibers allow these libraries to just work, no matter whether they're used in concurrent or traditional contexts.
