Are there any best practices to follow when using jQuery, Ajax, and PHP to dynamically update content on a webpage?

When using jQuery, Ajax, and PHP to dynamically update content on a webpage, it is important to follow best practices to ensure smooth functionality and security. Some best practices include validating user input on the server side, sanitizing data before processing it, and using prepared statements to prevent SQL injection attacks. 

<?php
// Validate user input
if(isset($_POST['data'])){
    $data = $_POST['data'];

    // Sanitize data
    $sanitized_data = filter_var($data, FILTER_SANITIZE_STRING);

    // Perform database operation using prepared statements
    $stmt = $pdo->prepare("INSERT INTO table_name (column_name) VALUES (:data)");
    $stmt->bindParam(':data', $sanitized_data);
    $stmt->execute();
}
?>
