$Menu = new Admin_Model_DbTable_Menu(); 
$row = $Menu->fetchRow($Menu->select()->where('id = ?', $id));
$Addmenu = new Admin_Form_Addmenu(); 
$Addmenu->populate($row->toArray());

$Menu = new Admin_Model_DbTable_Menu(); 
$row = $Menu->fetchRow($Menu->select()->where('id = ?', $id));
$Addmenu = new Admin_Form_Addmenu(); 
$Addmenu->populate($row->toArray());

当你从数据库中以对象的形式获取数据时，你可能想这样做:

// Suppose 'result' is the end product from some query $query

$result = $mysqli->query($query);
$result = db_result_to_array($result);

function db_result_to_array($result)
{
    $res_array = array();

    for ($count=0; $row = $result->fetch_assoc(); $count++)
        $res_array[$count] = $row;

    return $res_array;
}

从第一个谷歌点击“PHP对象到assoc数组”，我们有:

function object_to_array($data)
{
    if (is_array($data) || is_object($data))
    {
        $result = [];
        foreach ($data as $key => $value)
        {
            $result[$key] = (is_array($value) || is_object($value)) ? object_to_array($value) : $value;
        }
        return $result;
    }
    return $data;
}

与json_decode和json_encode的解决方案相比，这个解决方案似乎更快。下面是一个随机的基准测试(使用简单的时间测量):

$obj = (object) [
    'name'    =>'Mike',
    'surname' =>'Jovanson',
    'age'     =>'45',
    'time'    =>1234567890,
    'country' =>'Germany',
];

##### 100 000 cycles ######
* json_decode(json_encode($var))   : 4.15 sec
* object_to_array($var)            : 0.93 sec

get_object_vars($obj)怎么样?如果您只想访问对象的公共属性，它似乎很有用。

看到get_object_vars。

我使用这个(需要递归解决适当的关键字):

    /**
     * This method returns the array corresponding to an object, including non public members.
     *
     * If the deep flag is true, is will operate recursively, otherwise (if false) just at the first level.
     *
     * @param object $obj
     * @param bool $deep = true
     * @return array
     * @throws \Exception
     */
    public static function objectToArray(object $obj, bool $deep = true)
    {
        $reflectionClass = new \ReflectionClass(get_class($obj));
        $array = [];
        foreach ($reflectionClass->getProperties() as $property) {
            $property->setAccessible(true);
            $val = $property->getValue($obj);
            if (true === $deep && is_object($val)) {
                $val = self::objectToArray($val);
            }
            $array[$property->getName()] = $val;
            $property->setAccessible(false);
        }
        return $array;
    }

用法示例，代码如下:

class AA{
    public $bb = null;
    protected $one = 11;

}

class BB{
    protected $two = 22;
}


$a = new AA();
$b = new BB();
$a->bb = $b;

var_dump($a)

将打印这个:

array(2) {
  ["bb"] => array(1) {
    ["two"] => int(22)
  }
  ["one"] => int(11)
}
