What security measures should be implemented when sending SMS messages via PHP?

When sending SMS messages via PHP, it is important to implement security measures to protect sensitive information from being intercepted or tampered with. One way to enhance security is to use HTTPS when making API requests to the SMS gateway provider to encrypt the data being transmitted. Additionally, consider implementing authentication mechanisms such as API keys or tokens to verify the sender's identity before sending SMS messages. 

// Example code snippet using HTTPS and API key for sending SMS messages

$api_key = "your_api_key";
$message = "Hello, this is a test message.";
$phone_number = "1234567890";

$url = "https://api.smsprovider.com/send_sms";
$data = array(
    'api_key' => $api_key,
    'message' => $message,
    'phone_number' => $phone_number
);

$options = array(
    'http' => array(
        'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
        'method'  => 'POST',
        'content' => http_build_query($data)
    )
);

$context  = stream_context_create($options);
$response = file_get_contents($url, false, $context);

if ($response === false) {
    echo "Failed to send SMS message.";
} else {
    echo "SMS message sent successfully.";
}
