Note:
- Instead of installing local WAMP- or XAMPP-server I will be using Docker.
- Do not forget about a modern IDE like PhpStorm, which comes budled with all you will ever need.

# 1) Intro

Yii3 offers more basic applications: Web, Console, API. I will be using the API application:- https://docs.docker.com/get-started/introduction/get-docker-desktop/

# 2) Running the demo application

You may be surprised that docker-compose.yml is missing in the root. Instead the "make" commands are prepared.If you want to modify the data that was returned by the endpoint, just open the action-class (src/Api/IndexAction.php) and add one more element to the returned array.

# 3) Adding DB into your project

Your project now does not contain any DB. Let's add MariaDB and Adminer (DB browser) into file docker/dev/compose.yml:The web will be, from now on, available on URL http://localhost:9080 which is more handy than just ":80" I think.

# 4) Enabling MariaDB (MySQL) and migrations Now when your project contains MariaDB, you may wanna use it in the code ... ## a) Installing composer packages

After some time of searching you will discover you need to install these composer packages:> If you are using PhpStorm, find the small icon "Services" in the left lower corner (looks ca like a cog wheel), find item "Docker-compose: app-api", inside click the "app" service, then "yii3api_php" container and then hit the button "terminal" on the righthand side.

## b) Setting up composer packages

Follow their documentations. Quick links:```php
<&lt;?php declare(strict_types=1); ``` ## c) Create folder for migrations - src/Migration When this is done, call "composer du" or "make composer du" and then try "make yii list". You should see the migration commands. # 5) Creating a migration

Run the command to create a migration:```

# 6) Running the migrations
Try to run "make yii migrate:up" and you will see error "could not find driver", because file "docker/Dockerfile" does not install the "pdo_mysql" extention. Add it to the where "install-php-extensions" is called.

Then call:
- make down
- make build
