(PHP 4, PHP 5, PHP 7)
Return info about a group by group id
array posix_getgrgid ( int $gid )
Gets information about a group provided its id.
Parameters:
gid
The group id.
Returns:
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. |
Examples:
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 )
