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/.");

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.
