(PHP 4, PHP 5, PHP 7)
posix_getgrgid — Return info about a group by group id
$gid
)Gets information about a group provided its id.
gid
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
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. |
Example #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 )
