add a note
For windows users,
It will return TRUE for EXE extensions. I have checked for MSI, but it returns FALSE.
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.
