Creating a new application

To create a new application, we are going to use a little powerhouse of a tool known as yiic that comes packaged with the framework. This is a command-line tool that one can use to quickly jumpstart a brand new Yii application. It is not mandatory to use this tool, but it saves a lot of time and guarantees that the proper folder and file structure is in place.

To use this tool to create your first Yii application, open up a shell window, and navigate to a place in your filesystem where you will want to create your application's folder structure. For the purpose of this demo application, we will assume the following:

• YiiRoot is the folder where you have installed Yii

• WebRoot is configured as the document root of your web server

• From your command line, change to your WebRoot folder and execute the following:

  % cd WebRoot
  % YiiRoot/framework/yiic webapp demo
  Create a Web application under '/Webroot/demo'? [Yes|No] 
  Yes 
     mkdir /WebRoot/demo
     mkdir /WebRoot/demo/assets...
