以post格式将多维数组发送到web服务

$data = array(
    'name' => 'John Doe',
    'age' => 30,
    'contact' => array(
        'email' => 'john.doe@example.com',
        'phone' => '1234567890'
    ),
    'address' => array(
        'street' => '123 Main St',
        'city' => 'New York',
        'state' => 'NY'
    )
);

$jsonData = json_encode($data);

$url = 'http://example.com/api'; // 替换为你的web服务URL

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);

$data = json_decode(file_get_contents('php://input'), true);

// 处理接收到的数据
// ...

// 返回响应
$response = array('status' => 'success');
echo json_encode($response);
