Bug introduced by
It seems like $stream can also be of type false; however, parameter $handle of fwrite() does only seem to accept resource, maybe add an additional type check? ( Ignorable by Annotation )

If this is a false-positive, you can also ignore this issue in your code via the ignore-type  annotation

        fwrite(/** @scrutinizer ignore-type */ $stream, '1234');
