Get the real filename of file entity

Question

I'd like to get the real filename of a file entity.

My code is like this

    $filenames = [];
    foreach ($entity->$field->referencedEntities() as $image) {
      // Filename.
      $media = Media::load($image->id());
      $fid = $media->field_media_image->target_id;
      $file = File::load($fid);
      $filenames[] = $file->getFilename();
    };

    return $filenames;
  }

But filename returns the label of the file entity like so. my-image.jpg and using getFileUri() returns public://images/my-image_0.jpg I think because the image has been replaced at some point.

What I would like is just my-image_0.jpg but I can't seem to find a function to do it.

Thanks

The File class itself, in File::preCreate() uses the following code.

  // Automatically detect filename if not set.
  if (!isset($values['filename']) && isset($values['uri'])) {
    $values['filename'] = \Drupal::service('file_system')
      ->basename($values['uri']);
  }

In you case, the following code should be used.

$filenames[] = \Drupal::service('file_system')->basename($file->getFileUri());

In a context where dependency injection is available, the file_system service should be injected.
