http://viquanghoa.com/php-development/best-framework-2014/yii-framework/tao-url-chuyen-nghiep-cho-ung-dung-web-su-dung-yii-framwork.html

For this example we will create a news website has multi-level categories ¶

The requirement is:

URL for category has format: http://viquanghoa.com/php-development/best-framework-2014/yii-framework

Detailed news has URL format: http://viquanghoa.com/php-development/best-framework-2014/yii-framework/tao-url-chuyen-nghiep-cho-ung-dung-web-su-dung-yii-framwork.html

My English language is not good. :(

Thank you much!
