What are potential solutions for maintaining form data integrity while using URL rewriting in PHP?

When using URL rewriting in PHP, one potential solution for maintaining form data integrity is to store the form data in session variables before the redirect. This way, the form data can be accessed and validated after the redirect to ensure data integrity. 

```php
// Start the session
session_start();

// Store form data in session variables before the redirect
$_SESSION['form_data'] = $_POST;

// Redirect to the desired URL
header('Location: new_page.php');
exit();
```
This code snippet demonstrates how to store form data in session variables before redirecting to a new page. This allows you to maintain form data integrity while using URL rewriting in PHP.
