How can PHP form handling be utilized to improve the process of deleting an image and automatically refreshing the index.php page without using header() redirects?

When deleting an image in PHP, the form handling process can be improved by using AJAX to send a request to the server to delete the image without refreshing the entire page. This allows for a smoother user experience as the deletion can be done in the background without disrupting the user's current view. Additionally, by utilizing AJAX, we can update the index.php page automatically after the image is deleted without the need for header() redirects. 

// PHP code snippet using AJAX to delete an image and automatically refresh the index.php page

<?php
if(isset($_POST['delete_image'])){
    // Code to delete the image from the server
    
    // Return a success message
    echo "Image deleted successfully";
    exit;
}
?>

<!DOCTYPE html>
<html>
<head>
    <title>Delete Image</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

<body>

<!-- Form to delete the image -->
<form id="deleteForm">
    <input type="hidden" name="delete_image" value="1">
    <button type="submit">Delete Image</button>
</form>

<!-- Script to handle form submission with AJAX -->
<script>
$(document).ready(function(){
    $('#deleteForm').submit(function(e){
        e.preventDefault();
        
        $.ajax({
            type: 'POST',
            url: 'delete_image.php',
            data: $(this).serialize(),
            success: function(response){
                // Display success message
                alert(response);
                
                // Refresh the index.php page
                location.reload();
            }
        });
    });
});
