How can the issue of nested forms affecting form submission be resolved in PHP?

Issue: When using nested forms in HTML, the submission of the outer form may interfere with the submission of the inner form, resulting in unexpected behavior. To resolve this issue in PHP, you can use JavaScript to dynamically submit the inner form separately from the outer form. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process outer form data
    
    if(isset($_POST['inner_form_submit'])) {
        // Process inner form data
    }
}
?>

<form method="post">
    <!-- Outer form fields -->
    
    <form method="post">
        <!-- Inner form fields -->
        <input type="submit" name="inner_form_submit" value="Submit Inner Form">
    </form>
    
    <input type="submit" value="Submit Outer Form">
</form>
