close dbh in the subroutine

[Jeff Pang]

 Hi,

I created a $dbh object in the main body, and pass it to a subroutine, then 
close the $dbh in the subroutine, does it  influence the $dbh in the main?

$dbh = DBI->connect($data_source, $username, $auth, \%attr);
my_func($dbh);
$dbh->do(something); # will this broke?

sub my_func {
    my $dbh=shift;
    ...
    $dbh->close;
}

Thanks.
