Are there any specific PHP functions or libraries that can be used to play a sound notification in a web application?

To play a sound notification in a web application using PHP, you can use the HTML5 Audio element in conjunction with JavaScript. You can trigger the sound notification by dynamically creating an Audio element and playing the desired sound file when needed. 

<?php
// PHP code to trigger a sound notification in a web application

// This function will output the necessary JavaScript to play a sound notification
function playSoundNotification($soundFile) {
    echo "<script>
            var audio = new Audio('$soundFile');
            audio.play();
          </script>";
}

// Usage example
$soundFile = 'notification.mp3'; // Path to the sound file
playSoundNotification($soundFile);
?>
