PHP는 일괄 SMS 전송을 구현하기 위해 HTTP 요청을 보냅니다.

define('API_URL', 'http://example.com/api/send_sms');
define('API_TOKEN', 'abcdefg123456');
define('SENDER_NAME', 'My Company');

function sendSMS($recipients, $message) {
  // 构建请求数据
  $data = array(
    'token' => API_TOKEN,
    'sender' => SENDER_NAME,
    'message' => $message,
    'recipients' => $recipients
  );
  
  // 将数据编码为JSON格式
  $json = json_encode($data);
  
  // 初始化cURL
  $ch = curl_init();
  
  // 设置cURL选项
  curl_setopt($ch, CURLOPT_URL, API_URL);
  curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Content-Length: ' . strlen($json))
  );
  
  // 执行cURL请求
  $result = curl_exec($ch);
  
  // 解析API响应
  $response = json_decode($result, true);
  
  // 检查响应状态
  if ($response['status'] != 'success') {
    throw new Exception('SMS API Error: ' . $response['message']);
  }
  
  // 返回响应数据
  return $response['data'];
}

try {
  $recipients = array('+1234567890', '+0987654321');
  $message = 'Hello, world!';
  
  $result = sendSMS($recipients, $message);
  
  echo 'SMS sent successfully to ' . count($recipients) . ' recipients!';
} catch (Exception $e) {
