Description

array posix_getgrgid ( int $gid )

Gets information about a group provided its id.

Parameters

gid

The group id.

Return Values

The array elements returned are:

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.

ChangeLog

Version Description
4.2.0 Prior to this version, members was simply an integer representing the number of members in the group, and the member names were returned with numerical indices.

Examples

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
)
