This is true (under certain circumstances) in (at least) PHP 4 and 5. I filed it as a bug (see [1]) but it's the intended behavior -- writing less than the requested number of bytes is not considered an error. This means that you should only consider an fwrite successful if its return value is the same as the length of the string you passed to it. (fwrite fails in this particular way if the filesystem is full, or if the file was opened in read-only mode, and probably in yet other situations.) fwrite does return false (and trigger a warning) in certain cases; e.g., when it's passed an invalid file handle.
