将stdClass对象转换/转换为另一个类

$array = array(
    'name' => 'John',
    'age' => 30,
    'city' => 'New York'
);

// 使用(object)强制类型转换运算符
$stdClass = (object)$array;

// 使用settype()函数
$stdClass2 = new stdClass();
settype($stdClass2, 'array');
$stdClass2 = (object)$stdClass2;

class Person {
    public $name;
    public $age;
    public $city;
}

$person = new Person();
$person->name = 'John';
$person->age = 30;
$person->city = 'New York';

$stdClass = new stdClass();
$stdClass->name = $person->name;
$stdClass->age = $person->age;
$stdClass->city = $person->city;
