posix_getgrgid — Return info about a group by group id
$gid
   )Gets information about a group provided its id.
gidThe group id.
The array elements returned are:
| 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 gidparameter used when calling the
        function, and hence redundant. | 
| members | This consists of an array of string's for all the members in the group. | 
Example #1 Example use of posix_getgrgid()
<?php
$groupid   = posix_getegid();
$groupinfo = posix_getgrgid($groupid);
print_r($groupinfo);
?>
The above example will output something similar to:
Array
(
    [name]    => toons
    [passwd]  => x
    [members] => Array
        (
            [0] => tom
            [1] => jerry
        )
    [gid]     => 42
)
