note 54922 added to ref.dir

A quick recursive function I came up with to return the directory tree and files under a particular path in an associative array. For a file such as /the/directory/you/want/thefile.foo, $tree["the"]["directory"]["you"]["want"][0] = "thefile.foo" I needed it for a hacktastic way of storing variables temporarily in a directory structure. YMMV. <?php /*---------- Directory Tree to Array ----------// Takes base directory, returns an associative array containing each directory name as an associative key and each file as an indexed entry in the appropriate directory.
