Published on 2023-08-08 • Modified on 2023-08-08
This snippet shows how to get the path of a PHP interface or class. It can sometimes be helpful when debugging autoloading issues.
<?php
declare(strict_types=1);
namespace App\Controller\Snippet;
use App\Helper\String\AppStringInterface;
use function Symfony\Component\String\u;
/**
* I am using a PHP trait to isolate each snippet in a file.
* This code should be called from a Symfony controller extending AbstractController (as of Symfony 4.2)
* or Symfony\Bundle\FrameworkBundle\Controller\Controller (Symfony <= 4.1).
* Services are injected in the main controller constructor.
*/
trait Snippet266Trait
{
public function snippet266(): void
{
$reflector = new \ReflectionClass(AppStringInterface::class);
$fileName = $reflector->getFileName();
echo \sprintf('The physical path of the %s interface is %s.', AppStringInterface::class, u((string) $fileName)->split('strangebuzz.com')[1] ?? '');
// That's it! 😁
}
}
