You can get the public directory path from a Symfony controller using the following steps:

  1. Inject the KernelInterface dependency in your controller constructor or as a method argument.

use SymfonyComponentHttpKernelKernelInterface;

...

private $kernel;

public function __construct(KernelInterface $kernel)
{
    $this->kernel = $kernel;
}


  1. Use the getRootDir() method of the KernelInterface to get the Symfony application root directory.
1
$rootDir = $this->kernel->getRootDir();


  1. Concatenate the public directory path with the root directory path to get the absolute path to the public directory.
1
$publicDir = $rootDir . '/../public';


Now you can use the $publicDir variable to access files in the public directory from your controller. For example, you can create file paths or URLs to assets like CSS, JavaScript, or image files.
