The group information array
Element Description
name The 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.
passwd The 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.
gid Group ID, should be the same as the gid parameter used when calling the function, and hence redundant.
members This consists of an array of string's for all the members in the group.

        (

            [1] => jerry
        )
    [gid]     => 42
)
