Previous Comments: ------------------------------------------------------------------------ [2002-04-27 20:39:46] cynic@php.net something stinks here: [2002-04-27 10:41:44] sniper@php.net $filename=""; $bb = is_file($filename); var_dump($bb); int(0) yohgaki: $filename=""; $bb = is_file($filename); var_dump($bb); bool(false) so does is_file() return false or 0? plus it returned int(1) for you, which it shouldn't either (should return bool(true) instead). WTF? ------------------------------------------------------------------------ [2002-04-27 20:09:29] yohgaki@php.net I added following test case (ext/standard/tests/file/003.phpt) <?php $filename=""; $bb = is_file($filename); var_dump($bb); $aa = file_exists($filename); var_dump($aa); $filename="php.ini-dist"; $bb = is_file($filename); var_dump($bb); $aa = file_exists($filename); var_dump($aa); ?> Result: [yohgaki@dev HEAD]$ cat ext/standard/tests/file/003.out bool(false) bool(false) int(1) bool(true) ------------------------------------------------------------------------ [2002-04-27 19:57:58] yohgaki@php.net Just curious, is this fixed? (I was about to commit test case for this bug) [yohgaki@dev HEAD]$ ./cli-php ext/standard/tests/file/003.inc bool(false) bool(false) ------------------------------------------------------------------------ [2002-04-27 13:09:43] cynic@php.net Jani, the var_dump()s IMO show two bugs: the other is that is_file() returned int(0), while it's documented to be a bool type. could you check this too? ------------------------------------------------------------------------ [2002-04-27 10:41:44] sniper@php.net Duh. You're right, it's a bug. <?php $filename=""; $bb = is_file($filename); var_dump($bb); $aa = file_exists($filename); var_dump($aa); ?> Outputs: int(0) bool(true) --Jani ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
