There may be other checks that will throw a ValueException. I'm not sure
how it's implemented in detail because the filestat.c file doesn't
thrown an exception at all:
https://github.com/php/php-src/blob/1e9db80d7264911fa4089cb7e4b3dc7f97b19c6e/ext/standard/filestat.c
Can you tell me how you would check for NULL bytes?
Best,
Norbert
