#22610 [NEW]: is_file() safe mode restrictions on "." and ".."

From: mark_ford_uk at yahoo dot co dot uk Operating system: Red Hat Linux PHP version: 4.3.1 PHP Bug Type: Directory function related Bug description: is_file() safe mode restrictions on "." and ".." As of version 4.3, security was improved with regards to functions like is_file(). In particular, badly set file permissions will cause errors similar to the following: Warning: is_file() [function.is-file]: SAFE MODE Restriction in effect. The script whose uid is 10014 is not allowed to access ./filename/..... What I have discovered is, if I use is_file() on the filenames "." and ".." my script will break with errors like those above. Is this a bug?
