INVO

INVO is the sample invoicing application for the Phalcon Framework. It showcases CRUD management (companies, products, product types, invoices), forms, ACL-based access control and session authentication.

It runs on Phalcon v5 (the C extension, default) and on Phalcon v6 (the phalcon/phalcon package, currently alpha) from the same source.

Requirements

• PHP 8.2 – 8.5
• MySQL 8.0 (provided by the Docker stack)
• Docker + Docker Compose (recommended), or a local PHP with the Phalcon extension

Quick start (Docker)

cp .env.example .env
docker compose up -d --build

# Create the database schema (migrations are not run on boot)
docker compose exec app composer migrate

Note: app is the Compose service name, used as-is by docker compose exec above. The running container, however, is named ${PROJECT_PREFIX}-app - invo-app by default, set via PROJECT_PREFIX in .env. If you address it with plain docker exec, type your container name instead, e.g. docker exec invo-app composer migrate (substitute your own prefix).

Then open http://localhost:8080 (override the host port with APP_PORT in .env).

Log in with the seeded demo account: demo / phalcon.

Choosing the Phalcon version

docker compose up -d --build                      # v5 (C extension, default)
PHALCON_VARIANT=v6 docker compose up -d --build   # v6 (phalcon/phalcon, alpha)

The two are mutually exclusive: the v5 image installs the C extension, the v6 image installs the pure-PHP package instead.

Choosing the PHP version

The image is built for one PHP version at a time, selected with the PHP_VERSION build arg (default 8.5; supported 8.2–8.5):

docker compose up -d --build                  # PHP 8.5 (default)
PHP_VERSION=8.2 docker compose up -d --build  # PHP 8.2
PHP_VERSION=8.3 docker compose up -d --build  # PHP 8.3
PHP_VERSION=8.4 docker compose up -d --build  # PHP 8.4

PIE compiles the Phalcon C extension (and pcov) from source for the selected version. The container keeps the same name (invo-app), so each rebuild replaces the previous one. To run several versions side by side, give each its own Compose project and prefix:

PHP_VERSION=8.2 PROJECT_PREFIX=invo82 docker compose -p invo82 up -d --build
# then: docker exec -w /srv invo82-app composer test

Composer scripts

Run them inside the container, e.g. docker compose exec app composer cs:

Script	Description
composer cs	PHP_CodeSniffer (PSR-12)
composer cs-fix	Auto-fix coding standard issues (phpcbf)
composer cs-fixer	PHP CS Fixer (dry-run)
composer cs-fixer-fix	Apply PHP CS Fixer
composer analyze	PHPStan static analysis
composer test	PHPUnit suites (unit, functional)
composer test-coverage	PHPUnit + Clover coverage (tests/_output/coverage.xml)
composer migrate	Run database migrations (phalcon/migrations)

composer analyze resolves Phalcon classes from the phalcon/phalcon (v6) source, so run it where the v5 C extension is not loaded (the CI quality job, or a plain host). The coding-standard and test scripts are unaffected.

Running the tests

The suite is split into two PHPUnit testsuites - unit and functional. The functional tests dispatch the application in-process through phalcon/talon, so no web server is needed.

docker compose up -d --build
docker compose exec app composer migrate          # once - create the schema

docker compose exec app composer test             # the full suite
docker compose exec app composer test-coverage    # + Clover coverage in tests/_output

Test secrets

The test configuration lives in tests/.env.test and is loaded automatically by tests/bootstrap.php - you do not need to supply anything by hand:

Variable	Value	Purpose
DB_USERNAME / DB_PASSWORD	root / secret	matches the MySQL container's root password
DB_NAME	invo	the migrated test database

tests/.env.test is loaded with Dotenv's immutable loader, so any variable already set in the environment takes precedence - the same suite runs unchanged inside Docker (service-name host mysql) and on a native host or in CI (loopback 127.0.0.1). The only secret that is not local is SONAR_TOKEN, a GitHub Actions secret used solely by the sonarqube job.

Updating Phalcon

• v5 - bump PHALCON_V5_CONSTRAINT in resources/docker/Dockerfile and rebuild: docker compose build app. PIE compiles the C extension from source (this is the only way to update a C extension).
• v6 - docker compose exec app composer update phalcon/phalcon (no rebuild). Dependabot opens the bump PR automatically.

Project layout
