How can the PHP code be optimized to improve the performance of updating and refreshing the table data?

To optimize the performance of updating and refreshing table data in PHP, you can use AJAX to asynchronously update the table without reloading the entire page. This will reduce server load and improve user experience by making the updates faster and more seamless. 

<?php
// PHP code to update and refresh table data using AJAX

// Check if AJAX request is being made
if(isset($_POST['update_data'])) {
    // Update table data here

    // Return updated data as JSON response
    $updatedData = array(/* updated data */);
    echo json_encode($updatedData);
    exit;
}

// Your HTML table
?>

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
$(document).ready(function() {
    // Function to update table data
    function updateTableData() {
        $.ajax({
            url: 'your_php_file.php',
            type: 'POST',
            data: {update_data: true},
            success: function(response) {
                // Update table with new data
                // Example: $('#your_table_id').html(response);
            },
            error: function(xhr, status, error) {
                console.log('Error updating table data');
            }
        });
    }

    // Call updateTableData function on page load or any event trigger
    updateTableData();
});
</script>
