                                posix_getgrgid

   (PHP 3>= 3.0.13, PHP 4 )
   posix_getgrgid -- Return info about a group by group id

Description

   array posix_getgrgid ( int gid)

   Returns an array of information about a group and FALSE on failure. If
   gid isn't a number then NULL is returned and an E_WARNING level error
   is generated.

   Example 1. Example use of posix_getgrgid()
   <?php
   $groupid   = posix_getegid();
   $groupinfo = posix_getgrgid($groupid);
   print_r($groupinfo);
   ?>

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

     Note: As of PHP 4.2.0, members is returned as an array of member
     usernames in the group. Before this time it was simply an integer
     (the number of members in the group) and the member names were
     returned with numerical indices.
