PHP扩展:如何返回新的类对象

// 定义新的类对象结构体
typedef struct {
    zend_object obj;
    int value;
} my_class_object;

// 定义类的属性和方法
zend_property_entry my_class_properties[] = {
    ZEND_PROPERTY_END()
};

zend_function_entry my_class_methods[] = {
    ZEND_FE_END
};

// 定义类的构造函数和析构函数
static zend_object* my_class_create_object(zend_class_entry* ce) {
    my_class_object* obj = (my_class_object*)ecalloc(1, sizeof(my_class_object));
    zend_object_std_init(&obj->obj, ce);
    obj->obj.handlers = zend_get_std_object_handlers();
    return &obj->obj;
}

static void my_class_free_object(zend_object* object) {
    my_class_object* obj = my_class_object_from_obj(object);
    zend_object_std_dtor(&obj->obj);
    efree(obj);
}

// 注册类对象
zend_class_entry my_class_ce;
zend_class_entry* my_class_entry;

PHP_MINIT_FUNCTION(my_extension) {
    // 初始化类对象
    INIT_CLASS_ENTRY(my_class_ce, "MyClass", my_class_methods);
    my_class_entry = zend_register_internal_class(&my_class_ce);
    my_class_entry->create_object = my_class_create_object;
    memcpy(&my_class_handlers, zend_get_std_object_handlers(), sizeof(zend_object_handlers));
    my_class_handlers.offset = XtOffsetOf(my_class_object, obj);
    my_class_handlers.free_obj = my_class_free_object;

    // 注册类对象
    zend_register_internal_class_ex(&my_class_ce, NULL);
    
    return SUCCESS;
}

PHP_FUNCTION(create_my_class) {
    // 创建新的类对象
    my_class_object* obj = (my_class_object*)zend_object_alloc(my_class_entry);
    zend_object* object = &obj->obj;
    object_properties_init(object, my_class_entry);
    
    // 设置类对象的属性
    zend_update_property_long(my_class_entry, object, "value", sizeof("value") - 1, 123);
    
    // 返回类对象
    RETURN_OBJ(object);
}
