[Editor's Note: This is the expected behavior (at least on most Unix-like systems). If a directory is not executable, then you cannot get details on the files in the directory - this includes the permissions. --zak@php.net] This does not work on directories! look at this example: if(is_file("foo/bar")) print "found it"; if "bar" exists, but directory "foo" is not executable, you will NOT get "found it" as result.

david

to test whether the directory /home/david is executable (regardless of whether it is readable or writeable), issue the command: $my_isWriteable = @file_exists("/home/david/.") the @ gets rid of the warning when this command fails when the directory is not executable.

buuyo

The change doesn't appear to be documented, so I thought I would mention it. In php5, as opposed to php4, you can no longer rely on is_executable to check the executable bit on a directory in 'nix. You can still use the first note's method to check if a directory is traversable: @file_exists("adirectory/.");
