What considerations should be taken into account when using the ping attribute in HTML for tracking user interactions with PHP scripts?

When using the ping attribute in HTML to track user interactions with PHP scripts, it's important to consider the security implications. Make sure to sanitize and validate any data sent via the ping attribute to prevent injection attacks. Additionally, ensure that the PHP script handling the ping request is secure and only performs the necessary actions. 

<?php
// Sanitize and validate data sent via the ping attribute
$ping_data = filter_input(INPUT_GET, 'ping_data', FILTER_SANITIZE_STRING);

// Perform necessary actions based on the ping data
// For example, log the interaction to a database
$log_message = "User interaction: " . $ping_data;
// Insert $log_message into the database or perform other actions
?>
