Question

我正在尝试从一些开源创建一个新的Web应用程序的MySQLi驱动程序，并且无法通过未定义的属性通知。

Notice: Undefined property: mysqli_result::$rows in index.php

index.php的相关行

$query = $db->query("SELECT * FROM ".DB_PREFIX."setting WHERE store_id='".(int)$config->get('config_store_id')."' ORDER BY store_id ASC");

foreach($query->rows as $setting) {

if(!$setting['serialized']) {
    $config->set($setting['key'], $setting['value']);
} else {
    $config->set($setting['key'], unserialize($setting['value']));
}
}

我的mysqli控制器

class MySQLii {
private $link;

public function __construct($hostname, $username, $password, $database) {
    if(!$this->link = new mysqli($hostname, $username, $password, $database)) {
        trigger_error('Could not make a MySQLi database link using '.$username.'@'.$hostname);
        exit();
    }

    mysqli_query($this->link, "SET NAMES 'utf8'");
    mysqli_query($this->link, "SET CHARACTER SET utf8");
    mysqli_query($this->link, "SET CHARACTER_SET_CONNECTION=utf8");
    mysqli_query($this->link, "SET SQL_MODE = ''");
}

public function query($sql) {
    if($this->link) {
        $resource = mysqli_query($this->link, $sql);        

        if($resource) {
            if($resource instanceof mysqli_result) {
                $i=0;
                $data = array();
                while($result=$resource->fetch_object()) {
                    $data[$i]=$result;
                    $i++;
                }

                $result->close();

                $query = new stdClass();
                $query->row = isset($data[0]) ? $data[0] : array();
                $query->rows = $data;
                $query->num_rows = $i;
                unset($data);
                return $query;
            } else { return true; }
        } else {
            trigger_error('Error: '.mysqli_error($this->link).'<br>Error No: '.mysqli_errno($this->link).'<br>'.$sql);
            exit();
        }
    } 
}

和db控制器根据配置设置加载适当的驱动程序，在这种情况下是mysqli驱动程序......

class DB {
private $driver;

public function __construct($driver, $hostname, $username, $password, $database) {
    if(file_exists(DIR_DATABASE.$driver.'.php')) {
        require_once(DIR_DATABASE.$driver.'.php');
    } else {
        trigger_error('Could not load database file '.$driver.'.');
        exit();
    }

    $this->driver = new $driver($hostname, $username, $password, $database);
}

public function query($sql) {
    return $this->driver->query($sql);
}

public function escape($value) {
    return $this->driver->escape($value);
}

public function countAffected() {
    return $this->driver->countAffected();
}

public function getLastId() {
    return $this->driver->getLastId();
}
}

有没有理由我的index.php没有识别stdClass并且告诉我$ query-＆gt;行不是属性？顺便说一句，这个代码（几乎相同）与mysql而不是mysqli工作得很好！

注意：未定义的属性：index.php中的mysqli_result :: $ rows
