PHPCI

PHPCI is a free and open source continuous integration tool specifically designed for PHP. We've built it with simplicity in mind, so whilst it doesn't do everything Jenkins can do, it is a breeze to set up and use.

Please be aware that this is a brand new project, in an alpha state, so there will be bugs and missing features.

##What it does:

• Clones your repository from Github or Bitbucket (support for standard Git repositories coming soon.)
• Allows you to set up and tear down test databases.
• Installs your project's Composer dependencies.
• Runs through any combination of the following plugins:
  • PHP Unit
  • PHP Mess Detector
  • PHP Copy/Paste Detector
  • PHP Code Sniffer
• You can mark directories for the plugins to ignore.
• You can mark certain plugins as being allowed to fail (but still run.)

##What it doesn't do (yet):

• Virtualised testing.
• Multiple PHP-version tests.
• Multiple testing workers.
• Install PEAR or PECL extensions.
• Deployments.
• Success / Failure emails.

##Installing PHPCI: ####Pre-requisites:

• PHP 5.3+
• A web server. We prefer nginx.
• The YAML extension: pecl install yaml
• A MySQL server to connect to (doesn't have to be on the same server.)
• PHPCI needs to be able to run exec(), so make sure this is not disabled.

####Installing from Github:

• Step 1: git clone https://github.com/Block8/PHPCI.git
• Step 2: cd PHPCI
• Step 3: php install.php
  • When prompted, enter your database host, username, password and the database name that PHPCI should use.
  • The script will attempt to create the database if it does not exist already.
  • If you intend to use the MySQL plugin to create / destroy databases, the user you entered above will need CREATE / DELETE permissions on the server.
• Add a virtual host to your web server, pointing to the directory you cloned PHPCI into.
• You'll need to set up rewrite rules to point all non-existant requests to PHPCI.

Apache Example:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]

Nginx Example:

location / {
    try-files $uri $uri/ index.php
}

Finally, you'll want to set up PHPCI to run as a regular cronjob, so run crontab -e and enter the following:

* * * * * /usr/bin/php /path/to/phpci/cron.php

Obviously, make sure you change the /path/to/phpci to the directory in which you installed PHPCI, and update the PHP path if necessary.

##Adding support for PHPCI to your projects: Similar to Travis CI, to support PHPCI in your project, you simply need to add a phpci.yml file to the root of your repository. The file should look something like this:

setup:
	mysql:
		- "DROP DATABASE IF EXISTS test;"
		- "CREATE DATABASE test;"
		- "GRANT ALL PRIVILEGES ON test.* TO test@'localhost' IDENTIFIED BY 'test';"
	composer:
		action: "install"

ignore:
	- "vendor/"
	- "tests/"

test:
	php_unit:
		directory: "tests/"
	php_mess_detector:
		allow_failures: true
	php_code_sniffer:
		standard: "PSR2"
	php_cpd:
		allow_failures: true

complete:
	mysql:
		- "DROP DATABASE IF EXISTS b8_test;"

As mentioned earlier, PHPCI is powered by plugins, there are several phases in which plugins can be run:

• setup - This phase is designed to initialise the build procedure.
• test - The tests that should be run during the build. Plugins run during this phase will contribute to the success or failure of the build.
• complete - Always called when the test phase completes, regardless of success or failure.
• success - Called upon success of the test phase.
• failure - Called upon the failure of the test phase.

The ignore section is merely an array of paths that should be ignored in all tests (where possible.)
