How can PHP be used to automatically play a sound when there is a change detected in a database?

To automatically play a sound when a change is detected in a database, you can use PHP in conjunction with AJAX to periodically check for updates in the database. When a change is detected, PHP can send a signal to the front end to play a sound using JavaScript. 

<?php
// Database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check for changes in the database
$query = "SELECT * FROM table";
$result = $conn->query($query);

if($result->num_rows > 0){
    // Change detected, send signal to play sound
    echo "<script>new Audio('sound.mp3').play();</script>";
}
?>
