This article explores PHPCI, a continuous integration (CI) service for PHP projects. It contrasts PHPCI with other popular CI tools like Jenkins and Travis CI, highlighting its strengths and weaknesses.

Key Takeaways:

• PHPCI streamlines the process of maintaining application quality by automating code checks at regular intervals or on every code push. This prevents flawed code from entering the main repository.
• Installation is straightforward via Composer, requiring subsequent setup of a cron job for automated builds. Plugin management is also handled through composer.json.
• PHPCI facilitates project addition, allowing users to define build phases (setup, test, complete, success, failure). It supports test databases and various PHP QA tools.
• While promising, PHPCI's user interface and feedback mechanisms could benefit from improvements for enhanced clarity and intuitiveness. It's a suitable choice for PHP-only projects as a Jenkins alternative.

Continuous Integration Explained:

A CI service automates quality checks on code. For instance, it might pull a Git repository, execute unit tests, perform code validation, and generate reports. Typically triggered by time intervals or code pushes (especially merge requests), CI ensures code quality before merging, preventing broken functionality. This automated validation keeps the main repository clean and meets requirements before accepting changes.

PHPCI Installation and Setup:

Installation uses Composer, followed by a database configuration and cron job creation for automated builds. Plugin installation and updates are managed via composer.json, requiring a composer update after adding plugins.

Adding and Configuring a Project:

Adding a project involves a simple form specifying the code location (GitHub, Bitbucket, or a custom URL). If a phpci.yml file isn't present, manual build configuration is needed. The build process comprises five phases: setup, test, complete, success, and failure.

Example phpci.yml Configuration:

This example ignores vendor, bin, and app directories, uses Composer for installation, enforces PSR2 compliance, runs unit tests, checks docblocks, and uses PHPMD, PHPCPD, and PHPLoc for quality analysis. Note that a test database is optional.

build_settings:
    ignore:
        - "vendor"
        - "bin"
        - "app"

setup:
    composer:
        action: "install"

test:
    php_unit:
        config:
            - "app/phpunit.xml.dist"
        coverage: "coverage"
        args: "--stderr"
    php_mess_detector:
        allow_failures: true
    php_code_sniffer:
        standard: "PSR2"
    php_cpd:
        allow_failures: true
    php_docblock_checker:
        allowed_warnings: 10
        skip_classes: true
    php_loc:
        directory: "src"

Conclusion and Comparison:

PHPCI offers a centralized solution for PHP QA, generating helpful overview graphs. However, its relatively young age shows in its UI design and documentation integration. While a good alternative to Jenkins for PHP-only projects, improvements in feedback clarity and UI design are needed. The author compares it favorably and unfavorably to Jenkins and the combination of Travis CI, Scrutinizer, and SensioLabs Insight, highlighting its niche within the CI landscape. The author concludes that while promising, it may benefit from further development before being used in production environments.
