+// 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
