Having issues with setting up yii2 basic framework and ibm bluemix - yii2

Question

Having issues with setting up yii2 basic framework and ibm bluemix.
I was using this link as a guide: https://github.com/Twanawebtech/yii2App-Bluemix/blob/master/README.md
Step 1a: clone the code and setup
Open your terminal
$ git clone https://github.com/Twanawebtech/yii2App-Bluemix.git
$ cd yii2App-Bluemix
Step 1b: Set cookie validation key in config/web.php file to some random secret string:
'request' => [
// !!! insert a secret key in the following (if it is empty)
- this is required by cookie validation
'cookieValidationKey' => '<secret random string goes here>',
],
Step 1c: You can then access the application through the following URL:
http://localhost/yii2App-Bluemix/web
you should see the Congratulations Screen
Step 1d: Manifest
Go back to the yii2App-Bluemix folder
and open the manifest file
rename name and host to the name you want to call it.
Go to the command prompt and using cloud Foundary CLI (once you have setup cloud Foundary CLI)
enter cf login
API endpoint: https://api.ng.bluemix.net
enter Email Address:
enter Password:
Select a space (if you have more than one space allocated)
Step 2: Push your code to Bluemix
$ cf push yii2App-Bluemix -b https://github.com/cloudfoundry/php-buildpack.git -s cflinuxfs2
Step 3: Access your app by entering the following URL into your browser:
http://yii2basic.mybluemix.net/yii
However I don't get the congratulations screen but instead I get the following which is the source code of the index.php file found in the web folder
What am I missing or forgot to do???
