posix_getgrnam — Return info about a group by name
$name
   )Gets information about a group provided its name.
nameThe name of the group
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.  This should be the same as
        the nameparameter used when
        calling the function, and hence redundant. | 
| 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 of the group in numeric form. | 
| members | This consists of an array of string's for all the members in the group. | 
Example #1 Example use of posix_getgrnam()
<?php
$groupinfo = posix_getgrnam("toons");
print_r($groupinfo);
?>
The above example will output something similar to:
Array
(
    [name]    => toons
    [passwd]  => x
    [members] => Array
        (
            [0] => tom
            [1] => jerry
        )
    [gid]     => 42
)
