posix_getgrnam -- Return info about a group by name
( string name )
Gets information about a group provided its name.
The name of the group
The array elements returned are:
Table 1. The group information array
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
name parameter used when
calling the function, and hence redundant.
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.
Group ID of the group in numeric form.
This consists of an array of
string's for all the members in the group.
Prior to this version, members was simply an integer representing the
number of members in the group, and the member names were returned
with numerical indices.
Example 1. Example use of posix_getgrnam()
$groupinfo = posix_getgrgid("toons");
The above example will output
something similar to:
[name] => toons
[passwd] => x
[members] => Array
 => tom
 => jerry
[gid] => 42
