Hi, Nikita,
Yes, of course. For example, loading views using TemplateViews pattern[1]:
```
namespace MyProjects\Framework;
abstract class TemplateView {
private const VIEW_SUBPATH = '/views/';
protected function includeView( string $viewName ) {
$filePath = str_replace('\\', '/', static::namespace ).
self::VIEW_SUBPATH;
$fileName =$filePath.$viewName.'.tpl';
if( file_exists($fileName) ) {
return include $fileName;
}
error_log("Not found view[$viewName] in path $filePath" };
}
}
```
```
namespace MyProject\CMS\Freelancer\Attachments;
class Budget extends TemplateView {
public function __toString() {
$this->includeView('full_budget');
}
}```
Regards
