获取PHPActiveRecord结果作为简单数组,而不是对象数组

Question

我想有一个简单的方法,可以将PHP Activerecord结果作为简单/关联数组,而不是ActiveRecord对象数组.

在Ruby中,我相信这可能是通过.map()方法完成的.(我不是红宝石家伙...)

我想要的是一个简单的方法调用,比如toArray()在Zend_DB_Table中,不是foreach,或类似的东西,但我似乎无法在他们的文档中找到它.

在PHP ActiveRecord中获取结果非常简单:

$settings = SystemSettings::all();

但它给出了这样的东西:

[0] => SystemSettings Object
    (
        [errors] => 
        [attributes:ActiveRecord\Model:private] => Array
            (
                [param] => author
                [value] => Hawle
            )

        [__dirty:ActiveRecord\Model:private] => Array
            (
            )

        [__readonly:ActiveRecord\Model:private] => 
        [__relationships:ActiveRecord\Model:private] => Array
            (
            )

        [__new_record:ActiveRecord\Model:private] => 
    )

[1] => SystemSettings Object
    (
        [errors] => 
        [attributes:ActiveRecord\Model:private] => Array
            (
                [param] => base_url
                [value] => example.com
            )

        [__dirty:ActiveRecord\Model:private] => Array
            (
            )

        [__readonly:ActiveRecord\Model:private] => 
        [__relationships:ActiveRecord\Model:private] => Array
            (
            )

        [__new_record:ActiveRecord\Model:private] => 
    )

虽然在很多情况下这真的很棒,但在这里,我只想拥有一个简单的数组,如下所示:

Array
    (
        [author] => Hawle
        [base_url] => example.com
    )

我有一个类似的问题,希望这可以帮助其他人偶然发现它.显然,这是phpactiverecord.org特有的.

在/lib/Model.php中我添加了以下函数:

public function to_array(array $options=array())
{
    return $this->serialize('array', $options);
}

在/lib/Serialization.php中,我添加了以下类

class arraySerializer extends Serialization
{
    public static $include_root = false;

    public function to_s()
    {
        return self::$include_root ? array(strtolower(get_class($this->model)) => $this->to_a()) : $this->to_a();
    }


}

然后我可以调用 - > to_array()并返回一个数组.

希望这可以帮助!
