Yii Application Development Cookbook

Errata

Although both author and PACKT Publishing have taken every care to ensure the accuracy of book content, mistakes do happen. If you find a mistake in the book—maybe a mistake in the text or the code—we would be grateful if you would report this. If it will be confirmed it will be listed at this page.

If you're not sure if it's errata or not, you can open a new thread at Yii framework forum.

The following is the list of errata for all the book editions available. Thanks for your reports.
