How can PHP be used to implement "Next" and "Previous" buttons for navigating through paginated data?

To implement "Next" and "Previous" buttons for navigating through paginated data in PHP, you can use URL parameters to keep track of the current page number. By incrementing or decrementing the page number when the respective button is clicked, you can dynamically generate the URLs for the next and previous pages. 

<?php
// Get current page number from URL parameter
$page = isset($_GET['page']) ? $_GET['page'] : 1;

// Calculate previous and next page numbers
$prevPage = ($page > 1) ? $page - 1 : 1;
$nextPage = $page + 1;

// Output "Previous" button
echo "<a href='?page=$prevPage'>Previous</a>";

// Output "Next" button
echo "<a href='?page=$nextPage'>Next</a>";
?>
