$name
) : arrayGets information about a group provided its name.
nameThe name of the group
Returns an array on success, 或者在失败时返回 FALSE.
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 name parameter 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. |
