Google App Engine - Separate Project Required? - php

Question

I'm trying to port a simple website across to the Google App Engine. My website uses PHP and accesses a MySQL database.
In the App engine I've created a project, e.g.: my-project.
Then within that project I did what I was told, to get a MySQL database up and running: create a SQL instance, download phpMyAdmin locally, create app.yaml file:
application: my-project
version: 1
module: default
runtime: php55
api_version: 1
handlers:
- url: /(.*\.(ico$|jpg$|png$|gif$))
static_files: \1
upload: (.*\.(ico$|jpg$|png$|gif$))
application_readable: true
- url: /(.*\.(htm$|html$|css$|js$))
static_files: \1
upload: (.*\.(htm$|html$|css$|js$))
application_readable: true
- url: /(.*\.(php$))
script: \1
login: admin
- url: /(.+)
script: index.php
login: admin
- url: /.*
script: index.php
login: admin
I then deployed the app and went to
https://phpmyadmin-dot-my-project.appspot.com
phpMyAdmin worked perfectly.
Next, I created followed the helloworld.php example:
https://cloud.google.com/appengine/docs/php/gettingstarted/helloworld
Again, that worked, with the PHP code executing on the server to display 'Hello world!'.
Finally, I went back to:
https://phpmyadmin-dot-my-project.appspot.com
but no dice, it just displays 'Hello world!'.
Must be something very basic that I'm missing, do I need to create a separate project for each?
E.g.:
1. create project with MySQL DB instance and phpMyAdmin
2. create project with the PHP files

In the app.yaml for phpmyadmin, I needed to change:
module: default to module: phpmyadmin
application: myapp-beta
version: 1
module: phpmyadmin
runtime: php55
api_version: 1
Same for the app.yaml file for helloworld. Just created a new module called helloworld.
Need to read up on YAML and modules... thanks!
