How To Install Yii2 Alpha In Windows using composer
php, yii2
Solution
As Ororuk said, you should simply try :
composer create-project yiisoft/yii2-app-basic c:\xampp\htdocs\basic\yiinew 2.0.0-alpha
This will install package `yiisoft/yii2-app-basic` (`2.0.0-alpha` version) in folder `c:/xampp/htdocs/basic/yiinew` (composer will create this folder if necessary).
EDIT : You should access this app using `http://localhost/basic/yiinew/web`
