How can the Web Notification API be utilized in PHP applications for sound notifications?

To utilize the Web Notification API for sound notifications in PHP applications, we can use JavaScript to trigger the notifications. We can create a JavaScript function that requests permission to show notifications and then displays a notification with a sound. 

<script>
// Request permission for notifications
Notification.requestPermission().then(function(result) {
  console.log('Notification permission:', result);
});

// Function to display a notification with sound
function showNotification() {
  var notification = new Notification('New Message', {
    body: 'You have a new message!',
    icon: 'path/to/icon.png'
  });

  // Play notification sound
  var audio = new Audio('path/to/notification-sound.mp3');
  audio.play();
}

// Call the showNotification function when needed
showNotification();
</script>
