How can PHP be used to continuously display the most current data from a database without requiring page refresh?

To continuously display the most current data from a database without requiring a page refresh, you can use AJAX in combination with PHP. AJAX allows you to make asynchronous requests to the server and update specific parts of the webpage without reloading the entire page. By using PHP to handle the database queries and return the updated data, you can dynamically update the content on the webpage. 

<?php
// Include your database connection file
include 'db_connection.php';

// Fetch the most current data from the database
$query = "SELECT * FROM your_table ORDER BY id DESC LIMIT 1";
$result = mysqli_query($connection, $query);
$data = mysqli_fetch_assoc($result);

// Output the data in JSON format
echo json_encode($data);
?>
