Are there any specific security considerations when using PHP template engines on hosting platforms like Strato?

When using PHP template engines on hosting platforms like Strato, it is important to ensure that the template files are not accessible directly by users. This can be achieved by placing the template files outside of the public directory or using .htaccess rules to restrict access to them.

// Example of placing template files outside of public directory
$templateDir = '/path/to/templates';
```

```php
// Example of using .htaccess rules to restrict access to template files
<FilesMatch "\.tpl$">
    Order allow,deny
    Deny from all
</FilesMatch>
