Download the PHP package gcworld/common without Composer

GCWorld Common

gcworld/common provides shared configuration and service-loading foundations for GCWorld applications. It combines YAML-backed configuration with a per-application singleton, lazy database and Redis connections, path helpers, and package/project version discovery.

Version

2.8.1

Requirements

• PHP 8.4 or newer
• Composer 2
• PDO and the PDO driver required by the configured database
• The Redis PHP extension

Installation

Install the package with Composer:

Application common class

Create one project-specific subclass and implement getEnvironment() using the application's CommonEnvironmentEnumInterface enum:

Resolve the shared instance and its services where needed:

getInstance() keeps a separate instance for each concrete subclass.

Configuration

Pass a YAML path through the subclass's $configPath property. When no path is set, CommonConfig searches upward from the package for config/config.yml. See config/config.example.yml for a complete starting point.

The primary sections are:

• database: named MySQL connections, aliases, ports, and TLS options
• cache: named standalone Redis or Redis Cluster connections
• paths.file: application filesystem paths
• paths.web: public base, temporary, and asset-cache paths
• common.sort: recursively sort the YAML keys once and reset the option
• common.resolve_hosts: resolve values stored under host keys

Additional YAML files can be merged through includes. Paths are relative to the main configuration file, and later files override matching values loaded earlier:

Configuration caching is enabled by default. After parsing the YAML file, Common writes a neighboring .php cache file and loads that file on later requests. Remove the generated cache file when changing YAML configuration so the updated values can be compiled.

Configuration files are trusted application input. Do not allow users to control configuration paths or file contents.

Database connections

getDatabase() creates a gcworld/database connection only when requested and reuses it for the remainder of the process. The default connection name is default:

A database entry can reference another configured entry with alias. Circular aliases are rejected. Use closeDatabase() to disconnect and remove a cached connection.

Redis connections

getCache() supports standalone Redis and Redis Cluster configurations, including authentication, timeouts, and persistent connections. It returns null when a named cache is not configured.

An instance:identifier value creates a distinct cached connection identity while using the configuration for instance:

closeCache() removes that connection from Common's in-process cache.

Paths and versions

getDirectory() reads from paths.file. getPath() reads from paths.web and derives its base URL from HTTP_HOST outside CLI requests. Only use that dynamic base URL when the web server or trusted proxy validates the host header.

getCommonVersion() reads this package's VERSION file. getProjectVersion() reads the consuming project's VERSION file from the expected Composer installation layout and falls back to COMMON-ONLY:<common-version> when no project version is available. Pass fresh: true to bypass the in-process project-version cache.

Local development

The repository includes a Docker Compose environment based on the same PHP image used by CI:

Copy docker-compose.override.yml.example to the ignored docker-compose.override.yml only when local Composer credentials or SSH keys are required inside the container.

The Composer quality suite includes syntax checks, PHPStan level 6 analysis, and PHPUnit regression tests. Run them independently with composer lint, composer phpstan, or composer test.

Releases

Releases use bare semantic-version tags such as 2.7.20. Before tagging a release:

1. Move the relevant notes from Unreleased to a matching version heading in CHANGELOG.md.
2. Update VERSION and the value immediately below ### Version in this file.
3. Push the release commit and matching tag.

GitHub Actions validates release metadata and the PHP 8.4/8.5 quality matrix before creating a GitHub Release from the matching changelog section. Release tags must not be moved or reused.
