Are there alternative methods, besides using a PC with a modem, to display incoming SMS messages on a monitor via a web page using PHP?

To display incoming SMS messages on a monitor via a web page using PHP without using a PC with a modem, you can utilize a third-party SMS gateway service that provides an API for receiving SMS messages. You can then use this API to fetch incoming messages and display them on a web page.

<?php

// Replace 'YOUR_API_KEY' and 'YOUR_API_SECRET' with your actual API credentials
$api_key = 'YOUR_API_KEY';
$api_secret = 'YOUR_API_SECRET';

// Make a request to the SMS gateway API to fetch incoming messages
$api_url = 'https://api.sms-gateway.com/incoming-messages';
$response = file_get_contents($api_url . '?api_key=' . $api_key . '&api_secret=' . $api_secret);

// Decode the JSON response
$messages = json_decode($response, true);

// Display the incoming SMS messages on the web page
foreach ($messages as $message) {
    echo 'From: ' . $message['from'] . '<br>';
    echo 'Message: ' . $message['message'] . '<br><br>';
}

?>
