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 — Zegt of een bestandsnaam een executable is
Beschrijving
bool is_executable
( string $filename
)
Geeft TRUE terug als de bestandsnaam bestaat en een executable is.
Vanaf PHP 5.0.0 is is_executable() bruikbaar onder Windows.
Example#1 is_executable() voorbeeld
<?php
$file = '/home/vincent/somefile.sh';
if(is_executable($file)) {
echo $file.' is executable';
} else {
echo $file.' is not executable';
}
?>
Note: The results of this function are cached. See clearstatcache() for more details.
Note: This function will not work on remote files as the file to be examined must be accessible via the servers filesystem.

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.
