What is a more efficient solution for handling user confirmation messages and database operations in PHP, considering client-side and server-side execution?

When handling user confirmation messages and database operations in PHP, it is more efficient to use AJAX to handle client-side interactions and server-side processing separately. This approach allows for a smoother user experience by updating the UI dynamically without refreshing the page and offloading database operations to the server.

// PHP code for handling user confirmation messages and database operations using AJAX

// Client-side code (JavaScript)
<script>
function confirmAction() {
    if (confirm('Are you sure you want to proceed?')) {
        // Make an AJAX request to the server
        var xhr = new XMLHttpRequest();
        xhr.open('POST', 'process.php', true);
        xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
        xhr.onreadystatechange = function() {
            if (xhr.readyState === XMLHttpRequest.DONE) {
                if (xhr.status === 200) {
                    alert(xhr.responseText); // Display server response
                }
            }
        };
        xhr.send();
    }
}
</script>

// Server-side code (process.php)
<?php
// Perform database operations here
// Return a response message
echo "Operation successful!";
?>
