What are the potential issues with using nested forms in PHP for form submission?

Potential issues with using nested forms in PHP for form submission include confusion with form data organization, difficulty in processing multiple forms on a single page, and potential conflicts with form validation and submission handling. To solve this, you can use unique form names and IDs for each nested form, and handle form submission separately for each form. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (isset($_POST['form1_submit'])) {
        // Process form 1 data
    } elseif (isset($_POST['form2_submit'])) {
        // Process form 2 data
    }
}
?>
