How to Contribute

Just new pull request (and we need unit tests for new features)

Code Requirements



  • master: For Swoole 4.6, which supports PHP 7.2+.
  • 4.5.x: For Swoole 4.5, which supports PHP 7.1+.

Dockerized Local Development

First, run following command to autoload PHP classes/files (no exra Composer packages to be installed):

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

Secondly, run next command to start Docker containers:

docker-compose up

Alternatively, if you need to rebuild the service(s) and to restart the containers:

docker-compose build --no-cache
docker-compose up --force-recreate

Now you can run unit tests included:

docker exec -t $(docker ps -qf "name=app") ./vendor/bin/phpunit


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

Examples of Database Connection Pool

docker exec -t $(docker ps -qf "name=app") bash -c "php ./examples/mysqli/base.php"
docker exec -t $(docker ps -qf "name=app") bash -c "php ./examples/pdo/base.php"
docker exec -t $(docker ps -qf "name=app") bash -c "php ./examples/redis/base.php"

Examples of FastCGI Calls

There is a fantastic example showing how to use Swoole as a proxy to serve a WordPress website using PHP-FPM. Just open URL 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 exec -t $(docker ps -qf "name=app") bash -c "php ./examples/fastcgi/greeter/call.php"
docker exec -t $(docker ps -qf "name=app") bash -c "php ./examples/fastcgi/greeter/client.php"
docker exec -t $(docker ps -qf "name=app") bash -c "php ./examples/fastcgi/proxy/base.php"
docker exec -t $(docker ps -qf "name=app") bash -c "php ./examples/fastcgi/var/client.php"

Compatibility Patch (Swoole version <= v4.4.12)

define('SWOOLE_USE_SHORTNAME', true); // or false (it depends on you)

Coding Style Checks and Fixes

To update Composer packages (optional):

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

To check coding standard violations:

docker run --rm -v "$(pwd)":/var/www -t phpswoole/swoole bash -c "composer cs-check"

To correct coding standard violations automatically:

docker run --rm -v "$(pwd)":/var/www -t phpswoole/swoole bash -c "composer cs-fix"
