**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.

    [name]    => toons
    [passwd]  => x
    [members] => Array
        (
            [0] => tom
            [1] => jerry
        )
    [gid]     => 42
)
