is_dir
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/.");
is_executable
(PHP 4, PHP 5)
is_executable — Tells whether the filename is executable
Description

)

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.
