I’m always scared by is_resource calls because of the long ongoing migration from resources to objects in PHP.
See https://php.watch/articles/resource-object
File handles are not planned to move to object yet but that may happen someday.

What about:

				if (is_string($content) || $content === null) {
					return false;
				}
				return $content;
