PHP: posix_getgrgid

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.

Пример 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 )

Замечание: 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.

in php-4.3 the array returned seems to have changed.



it now returns:



["name"] group name

["passwd"] group password

["members"] group members (array of usernames)

["gid"] numeric group id

okies...



This code should be considered as an OPTION only, it works under MY set of circumstances, and that is all I intended. The below funtion will return the NAME of the GROUP if provided with the Group ID#



  function RC_posix_getgrgid($gid) 

    {

    $LocationGroup = "/etc/group"; //EDIT THIS IF YOU HAVE A DIFFERENT OS. mine = debian

    $fp = fopen ("/etc/group","r");

    while ($groupinfo = fscanf ($fp, "%[a-zA-Z0-9]:x:%[0-9]:%[a-zA-Z0-9]\n")) 

        {

        list ($name, $groupID, $nfi) = $groupinfo;

        if ($groupID == $gid)

            {

            $returnval = $name;

            }

        }

    fclose($fp);

    if($returnval) { return $returnval; } else { return 0; }

    }
