What is the issue with transferring data from the first form to the second form in PHP?

When transferring data from the first form to the second form in PHP, the issue often arises due to the data being lost during the redirect. To solve this problem, you can store the form data in session variables before redirecting to the second form. This way, the data will persist across pages and can be accessed in the second form. 

// First form processing
session_start();
$_SESSION['form_data'] = $_POST;

header('Location: second_form.php');
exit;
```

In the second form, you can then retrieve the form data from the session variable and use it as needed.

```php
// Second form processing
session_start();

if(isset($_SESSION['form_data'])){
    $form_data = $_SESSION['form_data'];
    // Use the form data as needed
} else {
    // Handle case where form data is not available
}
