And to tell the truth, both solutions have their one pros and cons. Everything you can do in this case is to reduce the bootstrap of the framework by using With ReactPHP you can write a non-blocking code, all input-output operations execute concurrently and thus they don’t slow down the application.
So, in places where we have input-output (filesystem or network communication), we don’t deal with actual values but with promises. If you want to build a web-application you need to compose your app with these different building blocks by yourself.How does it work? Create a new controller This new controller has a dependency on the event loop. Our application IS already an HTTP server written in PHP. But the promise is pending now. By default controllers are stored inside You see it is just a plain PHP class. For traversing the DOM I’m going to use Symfony DomCrawler Component: composer require symfony/dom-crawler.
No.
To put the numbers into a larger perspective with cached results they are compared with results for the Symfony Proxied results (ran with PHP-FPM) and Varnish.
We discussed a new framework and how it became possible to make Symfony asynchronous and run... READ MORE.

You may consider it as an “asynchronous Symfony”, or “Symfony on top of ReactPHP”. But there is no framework here. If we don’t want the whole server to freeze we need to use promises here. The idea of this tutorial was to introduce you to a new approach to building PHP web-app.
As you know such operations are slow and thus they can slow down the server.
Symfony 4 introduced Flex which is a new way to build Web applications – instead of starting with a full-stack framework, Flex allows you to pick just the components you need and gradually evolve your installation so you can build a quick console app, a lightweight API, or a complete Web application using the same starting point.
DriftPHP project already has It installs all Composer dependencies and starts the server on As was previously said DriftPHP under the hood uses Symfony.
Let’s imagine that you are building a high-performance PHP application. Introducing PHP-Watcher 18 Oct 2019. It is obvious that the DB call is going to take some time.
It is a framework build on top of both Symfony and ReactPHP components.
Let’s add a We again receive a JSON response but now in a second. Your application IS the server itself. It has one method Let me show you an example that makes the usage of promises in the controller more clear. Drupal & Symfony day 2018 Tema: Sockets server with Symfony with ReactPHP Por: Simon Mora https://www.rootstack.com.
Inside the app, the code should execute asynchronously. You need to grab data from the database and return it.
Star the repositories if you support the initiative and … This part executes in a traditional synchronous (blocking) way because here we load all resources (twig templates, configuration files).
But the downside here is that your code is going to be blocking in most cases. Speaking of me previously I had two options: either use Symfony or ReactPHP. Comparing PHP-FPM, PHP-PM, Symfony Proxy and Varnish.
We don’t want one connection to wait for another.
Let’s simulate a DB call with a timer.
- dbergunder/reactphp-symfony Once the time is up the promise resolves with a response and the kernel returns this response to the client.
That something is a promise of the actual response.
You have an HTTP server, HTTP client, different clients for storages, and so on. It doesn’t freeze and wait for the promise.
