posix_getgrgid — Return info about a group by group id
posix_getgrgid ( int $gid ) : array
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); ?>
The above example will output something similar to:
Array
(
[name] => toons
[passwd] => x
[members] => Array
(
[0] => tom
[1] => jerry
)
[gid] => 42
)
