二十九:分别获取主子订单数据、数组映射成模型

一:主子订单数据

{"user_id":101,"order_status":1,"order_money":120, "order_items":[{"prod_id":102,"prod_name":"pname1","prod_price":10,"discount":9,"prod_num":5,"prod_remark":"备注1"},{"prod_id":101,"prod_name":"pname2","prod_price":12,"discount":8,"prod_num":2,"prod_remark":"备注2"}]}

主订单中含有子订单若干数据(子订单若干数据分别为数组)

二:数组映射成模型实体

function mapToModelsArrary(array $maps,$class){

    $ret=[];
    foreach($maps as $map){
        $getObject=mapToModel($map,$class);
        if($getObject){
            $ret[]=$getObject;
        }
    }
    return $ret;
}
function mapToModel(array $map,$class){//把数组映射成实体 (一维数组)
    try {
        $class_obj = new ReflectionClass($class);
        $class_instance=$class_obj->newInstance();//根据反射对象创建实例
        $methods=$class_obj->getMethods(ReflectionMethod::IS_PUBLIC);
        foreach ($methods as $method){
            if(preg_match("/^set(\w+)/",$method->getName(),$matches)){
                invokeSetterMethod($matches[1],$class_obj,$map,$class_instance);
            }
        }
        return $class_instance;
    } catch (Exception $e) {
        return null;
    }
}
