What are the potential issues with handling special characters like "&" in PHP when passing data between AJAX and PHP scripts?

Special characters like "&" can cause issues when passing data between AJAX and PHP scripts because they can be misinterpreted as separators in query strings. To solve this issue, you can use the `encodeURIComponent()` function in JavaScript to encode the data before sending it via AJAX, and then use `urldecode()` function in PHP to decode the data on the server side. 

$data = urldecode($_POST['data']);
