// Your Account SID and Auth Token from twilio.com/console
$sid = 'your_account_sid';

$twilio_number = 'your_twilio_number';

// Initialize the Twilio client
$client = new Client($sid, $token);

// The phone number you want to send the SMS to
$to_number = '+1234567890';

// The message you want to send
$message = 'Hello, this is a test message from Twilio!';

try {
    // Send the SMS

        $to_number,
        [
            'from' => $twilio_number,
            'body' => $message
        ]
    );
    echo "Message sent successfully!";
} catch (Exception $e) {
    echo "Failed to send message: " . $e->getMessage();
}
?>
