Are there any best practices for implementing sound notifications in PHP to ensure a seamless user experience?

When implementing sound notifications in PHP, it's important to ensure a seamless user experience by using asynchronous requests to play the sound without interrupting the user's interaction with the website. One common approach is to use JavaScript to trigger the sound notification while PHP handles the logic for when the notification should be triggered.

// PHP code to handle triggering sound notifications
<?php
// Check if notification should be triggered
if ($notification_needed) {
    // Output JavaScript code to play the sound
    echo '<script>new Audio("notification_sound.mp3").play();</script>';
}
?>
