note 44454 added to function.is-executable

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/."); ---- Manual Page -- http://www.php.net/manual/en/function.is-executable.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+44454 Delete -- http://master.php.net/manage/user-notes.php?action=delete+44454&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+44454&report=yes Search -- http://master.php.net/manage/user-notes.php
