Bug #71849 [NEW]: file_get_contents returns undocumented type

From: hanskrentel at yahoo dot de Operating system: Linux PHP version: 7.0.4 Package: *General Issues Bug Type: Bug Bug description:file_get_contents returns undocumented type Description: ------------ I managed to make file_get_contents() return NULL which is undocumented (string and FALSE is documented). Technically the case ("\0" as filename) triggers a warning so might not construe an error, but actually smells a lot like an error finally and should be FALSE. This would also reduce handling return value logic. So far it's merely unnoticed as undocumented, no idea if it's a technical difficulty to fix or just an oversight. As this is NUL byte related this might make underlying problems visible. As I'm undecided, I filed it as bug. It could be a documentation problem or security issue. Also a change request. As it could be all three, I filed it as bug which is undefined as well.
