Chmod Test

<?php
/**
 * Here's a little test to figure out how PHP handles this whole chmod
 * situation. We try both string values and plain int values to set the
 * access controls.
 *
 * It turns out that mkdir does not respect the sticky bit. An extra chmod is
 * needed to add it. Not even ignoring the umask helps. Is this a PHP bug?
