Catchable fatal error: Object of class dUser could not be converted to string in on line 16
当运行getUserByName时，提示：Catchable fatal error: Object of class dUser could not be converted to string in on line 16的错误。不知道是哪里的问题，请大家帮忙指导。谢谢！！！

PHP code

<?php

class dUser
{
    public function newpdo() {
        global $dbinfo;

        $dsn = "mysql:host={$dbinfo['host']};port={$dbinfo['port']};dbname={$dbinfo['dbname']}";
        $pdo = new PDO($dsn, $dbinfo['user'], $dbinfo['pwd'], array(PDO::ATTR_PERSISTENT => true));
        return $pdo;
    }

     public function getUserByName(&$info, $name) {
        $dbpdo = $this->newpdo();
        $sql = "SELECT * FROM `usermember` WHERE `user`=?";
        $st = $dbpdo->prepare('SELECT * FROM `usermember` WHERE `user`=?');
        $bRet = $st->execute(array($name));
        $info = $st->fetch(PDO::FETCH_ASSOC);

        return $bRet;
     }
}

?>

参数$name被带入了一个类dUser变量.
