A file_exists("index/nothing"); returns a stat error. -Don ------------------------------------------------------------------------ [2002-04-08 01:52:33] don@blacksun.org If you try to stat a file that appears to be in a directory, and that directory is actually a regular file instead, file_exists() throws a stat error instead of just returning false. Needless to say this makes checking user input a lot more difficult. I am forced to check the entire path to see if each part is a directory before finally checking the last part to see whether it exists. file_exists() is a function and should either return true or false. If the file exists it should return true. If it does not (for _whatever_ reason) it should return false. Side effects like a stat error are unwanted, and can provide useful information to someone trying to attack the site. -Don ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16483&edit=1
