先不说什么功能，只能说这种功能对我们来说太有用了。
refactor，这种重构，其实在ＺＳ和ＮＥＴＢＥＡＮＳ 中效果并没有现在这个软件（phpstorm）那么明显。看看它的功能就知道了。
官方网址（http://blog.jetbrains.com/webide/2011/05/extract-function-method-refactoring-for-php/）说：
We are working hard on new features for PhpStorm 2.1, and the ‘Extract Function/Method’ refactoring for PHP is one of them. This feature has been available since the first PhpStorm 2.1 EAP(106.444), and we are looking forward for your feedback.
Picture 1b: Select an expression
Invoke the refactoring from the menu ‘Refactor -> Extract Method‘ or using a hotkey. The default hotkey is Ctrl+Alt+M for Windows/Linux and Cmd+Opt+M for Mac.
Depending on the context of the selected code fragment, ‘Extract method’ (the code fragment is inside a method) (Picture 2b) or ‘Extract Function’(the code fragment is inside a function or script) (Picture 2a).
Picture 2a: ‘Extract Function’ dialog
Picture 2b: ‘Extract Method’ dialog
Enter the name of the new function/method. Press OK.
Picture 3a: The code fragment is replaced with a function call statement
Picture 3b: The expression is replaced with a method call expression
Picture 4a: Definition of the extracted function
Picture 4b: Definition of the extracted method
Develop with pleasure!

看完上面的内容，你是否觉 得，原来重构也可以这样简单？
如果到facebook上关注一下yii framework的群组，会发现有人在介绍yiicookbook.org，里面是一本关于1.1的书。
然后去yii framework官方上搜索一下phpstorm，会发现同一个人在说自己用phpstorm，问phpstorm有没有什么支持。结果官网说暂时好象不支持。。。
然后再搜索了一下，发现在yii的官网有一个简单的例子在说如何让项目支持yii framework。看了一下，发现，大多数都用过，只有第一点，说是把yiilite.php过滤掉。这个其实很重要了，否则有些变量就会出现提示两次。
OK，来看官网的wiki吧：http://www.yiiframework.com/wiki/92/configuring-phpstorm-ide-for-yii
Code completion
- Exclude yiilite.php from index:
- File → Settings → IDE Settings → File Types.
- yiilite.php to Ignore files and folders.
- Exclude not used directories, specify resources.
- File → Settings → Project settings → Directories.
- Mark framework/cli/views, protected/runtime and assets as excluded.
- Mark website root as resource root.
- Specify path to your PHP.
- File → Settings → Project settings → PHP → PHP Home.
- If your project uses common Yii framework folder you need to include it.
- File → Settings → Project settings → PHP → PHP Home → Add.
- Specify a path to framework directory.
- If you are writing unit tests you can include PHPUnit to get code completion:
- File → Settings → Project settings → PHP → PHP Home → Add.
- Specify a path to PHPUnit.
- Complete code: Ctrl+Space.
- Show method arguments: Ctrl+Q.
Testing
You should install PHPUnit to run unit tests.
- PHPUnit.
- Follow official PHPUnit installation guide.
- In your IDE: Run → Edit configurations.
- Press "+".
- Name: anything.
- Test: depending on what do you want to test select an appropriate option. Specify path.
- Use XML configuration file: specifying path to phpunit.xml. Often it's path_to_your_webroot/protected/tests/phpunit.xml.
- To run tests use SHIFT+F10.
OK，现在这样就可以简单的支持yii framework了。只是phpstorm还是有点小问题，因为提示的时候不会显示phpdoc的信息。纠结，啥时候会有doc的提示呢？
