Чтобы отправлять автоматические уведомления по SMS и электронной почте в PHP, вы можете использовать различные методы. Вот несколько примеров кода:

1. Использование встроенной функции PHP mail():

   $to = 'recipient@example.com';
   $subject = 'Notification';
   $message = 'This is a notification email.';
   // Set additional headers
   $headers = 'From: sender@example.com' . "\r\n" .
   'Reply-To: sender@example.com' . "\r\n" .
   'X-Mailer: PHP/' . phpversion();
   // Send the email
   $mailSent = mail($to, $subject, $message, $headers);
   if ($mailSent) {
   echo 'Email notification sent successfully.';
   } else {
   echo 'Failed to send email notification.';
   }

2. Использование сторонней библиотеки, например PHPMailer:

   require 'vendor/autoload.php';
   use PHPMailer\PHPMailer\PHPMailer;
   use PHPMailer\PHPMailer\Exception;
   $mail = new PHPMailer(true);
   try {
   $mail->setFrom('sender@example.com', 'Sender');
   $mail->addAddress('recipient@example.com', 'Recipient');
   $mail->Subject = 'Notification';
   $mail->Body = 'This is a notification email.';
   $mail->isSMTP();
   // Configure your SMTP settings
   $mail->Host = 'smtp.example.com';
   $mail->SMTPAuth = true;
   $mail->Username = 'your_username';
   $mail->Password = 'your_password';
   $mail->SMTPSecure = 'tls';
   $mail->Port = 587;
   $mail->send();
   echo 'Email notification sent successfully.';
   } catch (Exception $e) {
   echo 'Failed to send email notification. Error: ' . $mail->ErrorInfo;
   }

3. Использование API шлюза SMS:

   $apiUrl = 'https://api.example.com/sms/send';
   $apiKey = 'your_api_key';
   $phoneNumber = '1234567890';
   $message = 'This is a notification SMS.';
   $data = [
   'api_key' => $apiKey,
   'phone_number' => $phoneNumber,
   'message' => $message,
   ];
   $options = [
   'http' => [
       'method' => 'POST',
       'header' => 'Content-type: application/x-www-form-urlencoded',
       'content' => http_build_query($data),
   ],
   ];
   $context = stream_context_create($options);
   $response = file_get_contents($apiUrl, false, $context);
   if ($response === false) {
   echo 'Failed to send SMS notification.';
   } else {
   echo 'SMS notification sent successfully.';
   }
