hi ... i was hoping you all might give me some tips on how to verify a username in a table, right now i have this working and was wondering if this is optimal. if not, then any suggestions would be appreciated. 
$query = qq(SELECT * FROM users WHERE userid = \'$username\');

$sth = $dbh->prepare($query);
$sth->execute;

$userCount = 0;
while (($userid, $pwd) = $sth->fetchrow_array) {
    print $userid . "is a valid user";
    $userCount = 1;
}


if($userCount == 0){
    print "invalid user";
}
