What is Yii

What is Yii Best for?

Yii vs Other Frameworks?

• MVC (Model-View-Controller)

• Design pattern

• Full-stack framework with ready-to-use features:

query builders and ActiveRecord for both relational and NoSQL databases;

RESTful API development support;

multi-tier caching support;

and more.

• Extremely extensible.

• High performance is always a primary goal of Yii.

• Backed up by a strong core developer team, as well as a large community of

professionals constantly contributing to Yii's development.

Personal Opinion

B. Yii Users

Namespaces

⦿ Prefixes no longer used

⦿ Based on directory structure

e.g. yii\web\Request

Events

⦿ onEvent method definition no longer

needed

⦿ $component->on($eventName,

$handler);

Path Alias

⦿ Must use @

⦿ @yii means Yii installation directory

⦿ Closely related to class namespaces

View Class

⦿ $this in a view no longer means controller or

widget object

⦿ Smarty and Twig support added

⦿ Prado support removed

Models

⦿ formName() returns the form name (previously hardcoded)

⦿ Load() and loadMultiple() added to aid data population

⦿ New method: scenarios() to define which fields need to be validated

⦿ Safe validators discontinued, scenarios() define which are safe

Controllers

⦿ Render() and renderPartial() return content

instead of sending it out

⦿ One must echo contents now

Widgets

⦿ Simplified process

⦿ Use begin(), end() and widget() instead of

passing strings through beginWidget() and

endWidget().

Themes

⦿ CThemeManager is gone

⦿ Path maps

⦿ ['/web/views' => '/web/themes/basic’]
