Personally, I'm not. Use @ to surpress them. You cannot guarentee the filename you think doesn't exist with the file_exists() doesn't exist when you eventually fopen() it, otherwise. This problem falls into a category called "Race conditions". http://en.wikipedia.org/wiki/Race_condition and http://www.dwheeler.com/secure-programs/Secure-Programs-HOWTO/avoid-race.html.
