Proof of concept of asynchronous programming with Php 8.1 and Fiber.

Slip (pronounced like "sleep" in english) is a nano framework providing a non-blocking sleep function.

Slip has been presented in a short talk at ForumPhp 2021 (fr).

Don't. It's just a one file library for demonstration purpose only. If you want to try it in your own project, just copy the Slip.php file.

⚠️ Requires Php 8.1 ⚠️

Slip contains only 3 (documented) functions:

• wrap several functions in some Slip\Slipper objects
• use Slip\sleep() to pause your functions in a non-blocking way
• run your Slip\Slipper instances concurrently with Slip\Slipper::run().

Some examples are provided, using a Ping Pong analogy.

A ping and a pong functions are executed concurrently in a vanilla Php program.

A small program using Symfony Console Component, providing a ping and a pong commands. First, run composer install to install dependencies, then you can execute commands individually (with php console.php <cmd> <count>) or concurrently (with php console.php ping-pong <count>).

Previous example launches 1 application with several concurrent commands, but this one launches several concurrent applications with a single command. Be sure to install dependencies, then run it with php ping-pong.php.

It's a lame french joke, no offense… We are not looking for a logo.
