+By default, Yii uses PHP in view templates to generate content and elements. A web application view typically contains some combination of HTML, along with PHP `echo`, `foreach`, `if`, and other basic constructs. Using complex PHP code in views is considered to be bad practice. When complex logic and functionality is needed, such code should either be moved to a controller or a widget.

 Widgets

-Widgets are a self-contained building blocks for your views. A widget may contain advanced logic, typically takes some
-configuration and data and returns HTML. There is a good number of widgets bundled with Yii such as [active form](form.md),
-breadcrumbs, menu or [wrappers around bootstrap component framework](bootstrap-widgets.md). Additionally there are
-extensions providing additional widgets such as official one for jQueryUI components.
