题目描述补充：

在电商系统中，经常需要处理订单的相关操作，如订单创建、查询、更新和删除等。本题目聚焦于订单查询中的一个具体场景：根据用户ID和订单状态查询订单列表。系统需要能够接收用户ID和订单状态作为查询条件，返回符合这些条件的订单列表。订单状态可以是待支付、已支付、已发货、已取消等。

示例输入：

• 用户ID: 1001
• 订单状态: "已支付"

示例输出：

[
    {
        "orderId": "OD123456",
        "userId": 1001,
        "status": "已支付",
        "totalAmount": 199.99,
        "orderDate": "2023-04-01T12:00:00Z"
    },
    {
        "orderId": "OD789012",
        "userId": 1001,
        "status": "已支付",
        "totalAmount": 249.99,
        "orderDate": "2023-04-02T15:30:00Z"
    }
]

PHP 示例代码：

<?php

// 假设这是从数据库获取的订单数据模拟
function getOrdersByUserAndStatus($userId, $status) {
    $orders = [
        ["orderId" => "OD123456", "userId" => 1001, "status" => "已支付", "totalAmount" => 199.99, "orderDate" => "2023-04-01T12:00:00Z"],
        ["orderId" => "OD789012", "userId" => 1001, "status" => "已支付", "totalAmount" => 249.99, "orderDate" => "2023-04-02T15:30:00Z"],
        ["orderId" => "OD345678", "userId" => 1002, "status" => "待支付", "totalAmount" => 149.99, "orderDate" => "2023-04-03T08:00:00Z"],
    ];

    $filteredOrders = array_filter($orders, function($order) use ($userId, $status) {
        return $order['userId'] == $userId && $order['status'] == $status;
    });

    return $filteredOrders;
}

// 示例使用
$userId = 1001;
$status = "已支付";
$orders = getOrdersByUserAndStatus($userId, $status);
echo json_encode($orders, JSON_PRETTY_PRINT);

?>

Python 示例代码：

def get_orders_by_user_and_status(user_id, status):
    orders = [
        {"orderId": "OD123456", "userId": 1001, "status": "已支付", "totalAmount": 199.99, "orderDate": "2023-04-01T12:00:00Z"},
        {"orderId": "OD789012", "userId": 1001, "status": "已支付", "totalAmount": 249.99, "orderDate": "2023-04-02T15:30:00Z"},
        {"orderId": "OD345678", "userId": 1002, "status": "待支付", "totalAmount": 149.99, "orderDate": "2023-04-03T08:00:00Z"},
    ]
    
    filtered_orders = [order for order in orders if order['userId'] == user_id and order['status'] == status]
    return filtered_orders

# 示例使用
user_id = 1001
status = "已支付"
orders = get_orders_by_user_and_status(user_id, status)
print(json.dumps(orders, indent=4))

JavaScript 示例代码：

function getOrdersByUserAndStatus(userId, status) {
    const orders = [
        { orderId: "OD123456", userId: 1001, status: "已支付", totalAmount: 199.99, orderDate: "2023-04-01T12:00:00Z" },
        { orderId: "OD789012", userId: 1001, status: "已支付", totalAmount: 249.99, orderDate: "2023-04-02T15:30:00Z" },
        { orderId: "OD345678", userId: 1002, status: "待支付", totalAmount: 149.99, orderDate: "2023-04-03T08:00:00Z" },
    ];

    const filteredOrders = orders.filter(order => order.userId === userId && order.status === status);

    return filteredOrders;
}

// 示例使用
const userId = 1001;
const status = "已支付";
const orders = getOrdersByUserAndStatus(userId, status);
console.log(JSON.stringify(orders, null, 4));
