How to learn Yii?!
tutorial, tips, understanding, yii
Here is a step by step To-Do list for Yii beginners. The list is an advice of
what tutorials and documentation you can walk through to get a full
understanding of the Yii Framework. These can be a help to learn Yii.  


1. **Learn PHP**  
You need to know how to program in PHP. You can find many tutorials on the web,
or buy a book. If you'd like a book, I recommend [Larry Ullman's
Two web tutorials can be found on
[webmonkey](http://www.webmonkey.com/2010/02/php_tutorial_for_beginners/) and
2. **Learn OOP**  
You need to know the basics of how Object Oriented Programming works. Same as
above, use Google or buy a book. You need to read the [PHP manual on
OOP](http://php.net/manual/en/language.oop5.php). It will take you a few hours.
Another tutorial about OOP can be found
and a video tutorial
3. **MVC**  
It is **very important to understand** what the Model-View-Controller pattern
means! If you don't, you will think Yii is chaos. As soon as MVC
"clicks" in your mind, you will see the very logical pattern. Read up
on [one](http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller),
[two](http://www.yiiframework.com/doc/guide/1.1/en/basics.best-practices) and
[three](http://www.yiiframework.com/doc/guide/1.1/en/basics.mvc). You can also
find an article here about [Understanding
4. **jQuery**  
I highly recommend reading (or even rereading) the [Getting Started with
jQuery](http://docs.jquery.com/Tutorials:Getting_Started_with_jQuery) page from
jQuery.com. These are some basics you need to know, since Yii uses jQuery as
well.  If you want to dive more into jQuery, I added some more links at the
Extra's at the bottom.
5. **API pages**  
The following is important to always remember: You always need to open the API
pages on functions you're using. The descriptions of all functions of a language
can be found here. The API's are your memory, since your brain's memory can't
remember ALL functions of ALL programming languages. ;) For PHP, use the search
box on the top right of [PHP.net](http://www.php.net/). For jQuery, you can
search the [jQuery Docs](http://docs.jquery.com/Main_Page). And here is [Yii's

1. **Easy introduction**  
Visual explanation is the best! So check the
[screencasts](http://www.yiiframework.com/screencasts/). :) After that, read up
on [Larry's easy tutorial
2. **The Guide!**  
The [Definitive Guide](http://www.yiiframework.com/doc/guide/1.1/en/index) is
very helpful! Just walk through all pages from top to the bottom. _Tip: Also
check out the comments on the bottom of the pages._  After that, I
recommend reading this tutorial: [Under the Hood of Yii’s Component
3. **Doing stuff**  
Okay, now you should actually get your hands dirty! Either grab the [Yii Agile
Web Application
book, or do the [Blog tutorial](http://www.yiiframework.com/doc/blog/). (Or
both!) _Note: If you read the book, make sure you check the errata
Also, this book uses Yii 1.1.6. The book takes you on a tour to make an
issuemanagement system. Some bits don't work with later versions of Yii, so make
sure to use an older version while learning Yii using this book._
4. **Got confused what's happening?**  
You can trace all variables to the Yii Log to see what's in them. You can find
more info here: [log&debug vars using
Irreplaceable for everyone to see whats happening! This is the best trick you
ever learn: 
>   Yii::trace(CVarDumper::dumpAsString( $var ), 'NAMEOFYOURTRACE');

***WHAT THEN?***
1. **Extra's**  
There are a lot of good tips in the [Yii Application Development
Cookbook](http://yiicookbook.org/). (If you buy it, check the errata section on
their website.) Also check out the [Yii Wiki](http://www.yiiframework.com/wiki/)
and the [Yii Class Reference](http://www.yiiframework.com/doc/api/). _Tip: You
can view Yii source code directly in the API docs. Also, the lookup/search box
in there is invaluable._ 
2. **jQuery**  
Yii uses a lot of jQuery javascript. You really need a basic~good understanding
of jQuery for the things you go up against. You can find an elaborate tutorial
[here](http://jqfundamentals.com), and a jQuery for Beginners video tutorial can
be found
3. **Community**  
 If you have questions, head towards the [Community
forums](http://www.yiiframework.com/forum/) or the [irc chatroom at #yii on
4. **More tools**  
There are a lot of [extensions](http://www.yiiframework.com/extensions/) for
Yii. These are extra "toolboxes", made by the Yii community, that you
can re-use in your applications.  


Basics - can take days, weeks or years. ;)  
Yii - Step 1& 2, takes a few hours.  
The rest takes days, or a few weeks if you're doing things parttime. After all
that, you should go into the depths of building your own custom Yii stuff!  

Have fun with Yiiing!  
Kind regards,
