chroot -- change the root directory


bool chroot (string directory)

Changes the root directory of the current process to directory. Returns FALSE if unable to change the root directory, TRUE otherwise.

Note: It's not wise to use this function when running in a webserver environment, because it's not possible to reset the root directory to / again at the end of the request. This function will only function correct when running as CGI this way.
