Injecting the Symfony project root directory in your services with a bind

Published on 2023-09-28 • Modified on 2023-09-28

This snippet shows how to inject the Symfony project root directory in your services (or your controllers) with a bind. In a previous snippet, we saw various ways to get the Symfony project's root directory. But as of Symfony 3.3, the good practice is injecting this parameter with a bind in the services.yaml configuration file, as shown below.

services:
    _defaults:
        bind:
            string $projectDir: '%kernel.project_dir%'

        # // then inject in your services with:
        # public class myService
        # {
        #       public function __construct(string $projectDir)
        #       {
