What are the limitations of using AJAX in PHP for sending data to a separate PHP script like export.php?

One limitation of using AJAX in PHP for sending data to a separate PHP script like export.php is that the data may not be properly sanitized before being sent, leaving it vulnerable to security risks such as SQL injection or cross-site scripting attacks. To solve this issue, it is important to validate and sanitize the data before sending it to the export.php script to ensure the security of the application. 

// Validate and sanitize the data before sending it to export.php
$data = $_POST['data'];

// Example of sanitizing the data using htmlspecialchars
$sanitized_data = htmlspecialchars($data, ENT_QUOTES);

// Send the sanitized data to export.php using AJAX
// Add your AJAX code here
