chgrp

(PHP 3, PHP 4, PHP 5)

chgrp -- Changes file group

Description

bool chgrp ( string filename, mixed group )

Attempts to change the group of the file filename to group (specified by name or number). Only the superuser may change the group of a file arbitrarily; other users may change the group of a file to any group of which that user is a member.

Returns TRUE on success or FALSE on failure.

Note: This function will not work on remote files as the file to be examined must be accessible via the servers filesystem.

Note: When safe mode is enabled, PHP checks whether the files or directories you are about to operate on have the same UID (owner) as the script that is being executed.
