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)
}

你也可以在PHP中创建一个函数来转换对象数组:

function object_to_array($object) {
    return (array) $object;
}

class Test{
    const A = 1;
    public $b = 'two';
    private $c = test::A;

    public function __toArray(){
        return call_user_func('get_object_vars', $this);
    }
}

$my_test = new Test();
var_dump((array)$my_test);
var_dump($my_test->__toArray());

输出

array(2) {
    ["b"]=>
    string(3) "two"
    ["Testc"]=>
    int(1)
}
array(1) {
    ["b"]=>
    string(3) "two"
}

这里发布的所有其他答案都只使用公共属性。下面是一个使用反射和getter处理类javabean对象的解决方案:

function entity2array($entity, $recursionDepth = 2) {
    $result = array();
    $class = new ReflectionClass(get_class($entity));
    foreach ($class->getMethods(ReflectionMethod::IS_PUBLIC) as $method) {
        $methodName = $method->name;
        if (strpos($methodName, "get") === 0 && strlen($methodName) > 3) {
            $propertyName = lcfirst(substr($methodName, 3));
            $value = $method->invoke($entity);

            if (is_object($value)) {
                if ($recursionDepth > 0) {
                    $result[$propertyName] = $this->entity2array($value, $recursionDepth - 1);
                }
                else {
                    $result[$propertyName] = "***";  // Stop recursion
                }
            }
            else {
                $result[$propertyName] = $value;
            }
        }
    }
    return $result;
}

由于很多人发现这个问题是因为在动态访问对象属性时遇到了麻烦，我只想指出，你可以在PHP中这样做:

在上下文(删除HTML输出可读性):

$valueRows = json_decode("{...}"); // Rows of unordered values decoded from a JSON object

foreach ($valueRows as $valueRow) {

    foreach ($references as $reference) {

        if (isset($valueRow->{$reference->valueName})) {
            $tableHtml .= $valueRow->{$reference->valueName};
        }
        else {
            $tableHtml .= " ";
        }
    }
}

转换和删除烦人的星星:

$array = (array) $object;
foreach($array as $key => $val)
{
    $new_array[str_replace('*_', '', $key)] = $val;
}

也许，它会比使用反射更便宜。
