How does the formaction attribute in HTML5 impact PHP form handling?

When using the formaction attribute in HTML5, the form submission URL specified in this attribute takes precedence over the form's action attribute. This can impact PHP form handling if the PHP script that processes the form submission is expecting data from a different URL. To solve this issue, you can check the form submission URL in your PHP script to ensure it matches the expected URL. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST['submit'])) {
    if ($_SERVER['REQUEST_URI'] == '/expected-processing-url.php') {
        // Process the form submission
    } else {
        // Handle unexpected form submission URL
    }
}
?>
