3: // This file contains helper functions for testing open_basedir configuration
4: // Care must be taken with where the directories are created because different
5: // SAPIs set the working directory differently. So simply creating a directory
6: // relative to the current working directory like this: mkdir("blah") might
7: // actually create it in several different places depending on the SAPI..!
8: //
9: // Note also depending on the version of php being tested, so the open_basedir
10: // configuration may or may not be changeable from a script (PHP_INI_SYSTEM).
11: //
12: // For this reason we set the open_basedir to . (current directory) and then
13: // move around to various directories for testing using chdir(). This is NOT
14: // recommended for production use as . bypasses all semblence of security..!
15: //
16: // Although safe mode has been removed in php 6.0, open_basedir is still valid.
17: // See http://www.php.net/features.safe-mode for more information
