// This file contains helper functions for testing open_basedir configuration
// Care must be taken with where the directories are created because different
// SAPIs set the working directory differently. So simply creating a directory
// relative to the current working directory like this: mkdir("blah") might 
// actually create it in several different places depending on the SAPI..!
//
// Note also depending on the version of php being tested, so the open_basedir
// configuration may or may not be changeable from a script (PHP_INI_SYSTEM).
//
// For this reason we set the open_basedir to . (current directory) and then
// move around to various directories for testing using chdir(). This is NOT
// recommended for production use as . bypasses all semblence of security..!
//
// Although safe mode has been removed in php 6.0, open_basedir is still valid.
//      See http://www.php.net/features.safe-mode for more information
