First, run one of the following commands to install development packages using Composer:

docker run --rm -v "$(pwd)":/var/www -ti phpswoole/swoole composer update -n

# or, use the official Composer Docker image:
docker run --rm -v "$(pwd)":/app -ti composer update -n --ignore-platform-reqs

# or, use the local Composer if installed:
composer update -n --ignore-platform-reqs

Next, you need to start Docker containers:

docker compose up -d

Alternatively, if you need to rebuild some Docker image and to restart the containers:

docker compose build --progress plain --no-cache
docker compose up -d --force-recreate

Now you can create a bash session in the app container:

docker compose exec app bash

And run commands inside the container:

composer test

Or you can run commands directly inside the app container:

docker compose exec app composer test

Once you have Docker containers started (as discussed in previous section), you can use commands like following to run examples under folder examples.

docker compose exec app php examples/mysqli/base.php
docker compose exec app php examples/pdo/base.php
docker compose exec app php examples/redis/base.php

There is a fantastic example showing how to use Swoole as a proxy to serve a WordPress website using PHP-FPM. Just open URL http://127.0.0.1 in the browser and check what you see there. Source code of the example can be found here.

Here are some more examples to make FastCGI calls to PHP-FPM:

docker compose exec app php examples/fastcgi/greeter/call.php
docker compose exec app php examples/fastcgi/greeter/client.php
docker compose exec app php examples/fastcgi/proxy/base.php
docker compose exec app php examples/fastcgi/var/client.php

Here are all the third party libraries used in this project:

• The FastCGI part is derived from Composer package lisachenko/protocol-fcgi.
