$group_id): array|false
Gets information about a group provided its id.
group_id
The 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
group_id 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. |
false on failure.
示例 #1 Example use of posix_getgrgid()
<?php
$groupid = posix_getegid();
$groupinfo = posix_getgrgid($groupid);
print_r($groupinfo);
?>
以上例程的输出类似于：
Array
(
[name] => toons
[passwd] => x
[members] => Array
(
[0] => tom
[1] => jerry
)
[gid] => 42
)
