Symfony Runtime - A First Look

For the upcoming Symfony 5.3 release a new experimental component is announced: Symfony Runtime. In this talk we will look at what the runtime component is for, how it is used in a typical Symfony app running via php-fpm/php-cli and how you can adapt it for alternative runtimes like ReactPHP.

    When using Apache, you can con gure PHP as an Apache module or FastCGI using PHP FPM.

    The Runtime Component
    The Runtime Component decouples
    the bootstrapping logic from any
    global state to make sure the
    application can run with runtimes like
    PHP-FPM. ReactPHP, Swoole, etc.
    without any changes.
