对于您的情况，如果您使用“装饰器”或“日期模型转换”模式是正确的/漂亮的。例如:

你的模型

class Car {
    /** @var int */
    private $color;

    /** @var string */
    private $model;

    /** @var string */
    private $type;

    /**
     * @return int
     */
    public function getColor(): int
    {
        return $this->color;
    }

    /**
     * @param int $color
     * @return Car
     */
    public function setColor(int $color): Car
    {
        $this->color = $color;
        return $this;
    }

    /**
     * @return string
     */
    public function getModel(): string
    {
        return $this->model;
    }

    /**
     * @param string $model
     * @return Car
     */
    public function setModel(string $model): Car
    {
        $this->model = $model;

        return $this;
    }

    /**
     * @return string
     */
    public function getType(): string
    {
        return $this->type;
    }

    /**
     * @param string $type
     * @return Car
     */
    public function setType(string $type): Car
    {
        $this->type = $type;

        return $this;
    }
}

装饰

class CarArrayDecorator
{
    /** @var Car */
    private $car;

    /**
     * CarArrayDecorator constructor.
     * @param Car $car
     */
    public function __construct(Car $car)
    {
        $this->car = $car;
    }

    /**
     * @return array
     */
    public function getArray(): array
    {
        return [
            'color' => $this->car->getColor(),
            'type' => $this->car->getType(),
            'model' => $this->car->getModel(),
        ];
    }
}

使用

$car = new Car();
$car->setType('type#');
$car->setModel('model#1');
$car->setColor(255);

$carDecorator = new CarArrayDecorator($car);
$carResponseData = $carDecorator->getArray();

这样代码就会更漂亮，更正确。

这个答案只是这篇文章的不同答案的联合，但它是将具有简单值或数组的公有或私有属性的PHP对象转换为关联数组的解决方案…

function object_to_array($obj)
{
    if (is_object($obj))
        $obj = (array)$this->dismount($obj);
    if (is_array($obj)) {
        $new = array();
        foreach ($obj as $key => $val) {
            $new[$key] = $this->object_to_array($val);
        }
    }
    else
        $new = $obj;
    return $new;
}

function dismount($object)
{
    $reflectionClass = new \ReflectionClass(get_class($object));
    $array = array();
    foreach ($reflectionClass->getProperties() as $property) {
        $property->setAccessible(true);
        $array[$property->getName()] = $property->getValue($object);
        $property->setAccessible(false);
    }
    return $array;
}

将对象类型转换为数组。

$arr =  (array) $Obj;

它会解决你的问题。

下面是将PHP对象转换为关联数组的递归PHP函数:

// ---------------------------------------------------------
// ----- object_to_array_recursive --- function (PHP) ------
// ---------------------------------------------------------
// --- arg1: -- $object  =  PHP Object         - required --
// --- arg2: -- $assoc   =  TRUE or FALSE      - optional --
// --- arg3: -- $empty   =  '' (Empty String)  - optional --
// ---------------------------------------------------------
// ----- Return: Array from Object --- (associative) -------
// ---------------------------------------------------------

function object_to_array_recursive($object, $assoc=TRUE, $empty='')
{
    $res_arr = array();

    if (!empty($object)) {

        $arrObj = is_object($object) ? get_object_vars($object) : $object;

        $i=0;
        foreach ($arrObj as $key => $val) {
            $akey = ($assoc !== FALSE) ? $key : $i;
            if (is_array($val) || is_object($val)) {
                $res_arr[$akey] = (empty($val)) ? $empty : object_to_array_recursive($val);
            }
            else {
                $res_arr[$akey] = (empty($val)) ? $empty : (string)$val;
            }
            $i++;
        }
    }
    return $res_arr;
}

// ---------------------------------------------------------
// ---------------------------------------------------------

使用的例子:

// ---- Return associative array from object, ... use:
$new_arr1 = object_to_array_recursive($my_object);
// -- or --
// $new_arr1 = object_to_array_recursive($my_object, TRUE);
// -- or --
// $new_arr1 = object_to_array_recursive($my_object, 1);


// ---- Return numeric array from object, ... use:
$new_arr2 = object_to_array_recursive($my_object, FALSE);

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。

我在Laravel Collections中测试了它，这工作得很好。

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