Why Here A Extra Table ?


I try to follow the web application developement book.

At some point there is a part where relations are made among some tables.

I see there that the author made new tables to hold the relations.

But why not use the foreign key feature of mysql.


Which book are you talking about? As far as I know, there aren’t any about Yii 2.0 yet.

Im talking about the web application development with Yii and PHP.


OK. Moved to appropriate subforum. I can’t help with the book itself unfortunately.
