While googling Larry Ullman’s book on the Yii framework recently, I found that it wasn’t prominent in the search results, so lets boost its SEO! :D If you like developing with PHP, Yii is definitely worth a look.
The Yii Book is a good resource and example-filled manual covering the Yii Framework. Not an exhaustive resource on the Yii Framework, Larry will show you what you need to get started with producing quality apps. On a personal note, I have been reading his books for years and have found his style both reader-friendly and informative.
While not yet complete, the partial copy is available for purchase in ebook format with rights to updates as they become available. If you’re looking to learn about the Yii Framework, this is definitely a great resource to have. Why not check it out?
