How can the issue of losing POST variables during a redirect be addressed in PHP?

Issue: When redirecting in PHP using header("Location: newpage.php"), POST variables are lost. To address this, you can store the POST data in a session variable before the redirect and then retrieve it on the redirected page. 

// Store POST data in session variable before redirect
session_start();
$_SESSION['post_data'] = $_POST;

// Redirect to new page
header("Location: newpage.php");
exit;
```

On the redirected page (newpage.php), you can retrieve the POST data from the session variable like this:

```php
session_start();
if(isset($_SESSION['post_data'])) {
    $post_data = $_SESSION['post_data'];
    // Use the POST data as needed
    // Don't forget to unset or clear the session variable after use
    unset($_SESSION['post_data']);
}
