A namespace refers to a logical grouping of some class names so that they can be differentiated from other class names even if their names are the same. Do not confuse path alias with namespace. A path alias is merely a convenient way of naming a file or directory.
Yii is a high-performance, component-based PHP framework for developing large-scale Web applications rapidly. It enables maximum reusability in Web programming and can significantly accelerate your Web application development process. The name Yii (pronounced Yee or [ji:] ) is an acroynym for "Yes It Is!".
Conceptually Yii1 and Yii2 are quite similar, however Yii2 runs on newer PHP versions and utilizes namespaces, traits etc. Yii2 has also support for dependency injection through $container singleton available after initializing the framework.
You may try read this documentation http://yiiframework.ru/doc/guide/en/basics.namespace In general Yii namespaces - it is aliases for folders. I.E.
'aliases' => array(
'frontend' => dirname(__FILE__) . '/../..' . '/frontend',
'common' => dirname(__FILE__) . '/../..' . '/common',
'backend' => dirname(__FILE__) . '/../..' . '/backend',
'vendor' => dirname(__FILE__) . '/../..' . '/common/lib/vendor'
),
...
'import' => array(
'common.extensions.components.*',
'common.components.*',
'common.helpers.*',
'common.models.*',
'application.controllers.*',
// In result "common" = dirname(__FILE__) . '/../..' . '/common'
