My colleague Brent is currently creating a new package called spatie/async. This one will let you easily do some asynchronous parallel processing in PHP. In a new post on his blog Brent explains why we are creating the package and compares it to a few other solutions out there.
If you're into parallel PHP, you probably heard of Amp and ReactPHP. Our package aims not to compete with those two, as it only solves one tiny aspect of parallelism in PHP. We did however use both the packages to run some benchmarks against. Let's take a look at the results.
