<?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?
