What are the potential pitfalls of mixing PHP code with Smarty templates?

Mixing PHP code with Smarty templates can lead to code that is difficult to maintain and debug, as it can make the codebase harder to understand for developers who are not familiar with Smarty. To avoid this issue, it is recommended to keep PHP logic separate from the presentation layer by using Smarty only for templating purposes. 

```php
<?php

// Separate PHP logic from Smarty templates
$data = [
    'name' => 'John Doe',
    'age' => 30
];

$smarty->assign('data', $data);
$smarty->display('template.tpl');

?>
