Parameters

string $file_url: A file URL of a local file as generated by FileUrlGeneratorInterface::generateString().

Return value

string If the file URL indeed pointed to a local file and was indeed absolute, then the transformed, relative URL to the local file. Otherwise: the original value of $file_url.
