How can the Post/Redirect/Get pattern be implemented in PHP to improve user experience and prevent form resubmission issues?

Issue: The Post/Redirect/Get pattern is used to prevent form resubmission issues and improve user experience by redirecting users to a different URL after they submit a form. This helps avoid duplicate form submissions when a user refreshes the page. PHP Code Snippet: 

```php
// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data

    // Redirect to a different URL to prevent form resubmission
    header("Location: success.php");
    exit;
}
```

In the above code snippet, we first check if the form is submitted using the `$_SERVER["REQUEST_METHOD"]` variable. If the form is submitted, we process the form data and then redirect the user to a different URL using the `header("Location: success.php")` function. This prevents form resubmission when the user refreshes the page.
