How can JavaScript be utilized to trigger HTTP links in the background for PHP-controlled home automation systems like the XS1 from EZ Control?

To trigger HTTP links in the background for PHP-controlled home automation systems like the XS1 from EZ Control, you can use JavaScript to make AJAX requests to the PHP server, which can then send the HTTP requests to the XS1 device. This way, you can trigger actions on the home automation system without reloading the page or interrupting the user's experience.

<?php
// PHP code to handle AJAX request and trigger HTTP link in the background

if(isset($_POST['action'])) {
    $url = $_POST['url'];
    
    // Use cURL to send HTTP request to XS1 device
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($ch);
    curl_close($ch);
    
    // Return response back to JavaScript
    echo $response;
}
?>
