(2) Update Composer to the latest version

If you have already installed Composer please Make sure you are using the latest version. You can use the composer self-update command to update Composer to the latest version.

Note: During Yii installation, Composer needs to request a lot of information from the Github API. The number of requests depends on what your application depends on and may be greater than the Github API rate limit. If this limit is reached, Composer may ask you to provide your Github login credentials to obtain a Github API access token.

(3) Install Yii application template

After installing Composer, you can install Yii by running the following command under a web-accessible folder Application Template:

composer create-project --prefer-dist yiisoft/yii2-app-basic basic

This will install the latest stable version of the Yii application template in a directory called basic . You can choose a different directory name if needed.

If you want to install the latest version of Yii, you can use the following command

composer create-project --prefer-dist --stability=dev yiisoft/yii2-app-basic basic

Please note that the development version of Yii should not be used in production as it may Break your running code.
