The array elements returned are:

ElementDescription
nameThe name element contains the name of the group. This is a short, usually less than 16 character "handle" of the group, not the real, full name.
passwdThe passwd element contains the group's password in an encrypted format. Often, for example on a system employing "shadow" passwords, an asterisk is returned instead.
gidGroup ID, should be the same as the gid parameter used when calling the function, and hence redundant.

Examples

Example #1 Example use of posix_getgrgid()

<?php $groupid   = posix_getegid( $groupinfo = posix_getgrgid($groupid print_r($groupinfo ?>
