Returns an array of information about a group and
FALSE on failure. If gid
isn't a number
then NULL is returned and an E_WARNING
level error is generated.
Note: As of PHP 4.2.0, members is returned as an array of member usernames in the group. Before this time it was simply an integer (the number of members in the group) and the member names were returned with numerical indices.
