Setting up Jenkins Continuous Integration for a PHP project on a Mac Mini Server

With one of my previous post I have run through the steps involve in setting up Jenkins and today I’m going to discuss about the how to get a PHP project integrated with Jenkins on a Mac Mini server(It’s a pain in the ass compared to a Linux box when it comes to setting up Jenkins server).

List of items required

We need to enable and install following modules both on Jenkins as well as on PHP.

  • Jenkins
    • Checkstyle
    • CloverPHP
    • Dry
    • HTML Publisher
    • JDepend
    • Plot
    • PMD
    • Violation
    • xUnit
    • JSHint Report
    • Apache Ant
    • Subversion
    • Jenkins Email Extension
  • PHP modules using the PEAR package
    • phploc
    • pdepend
    • phpmd
    • phpcs
    • phpcpd
    • phpdox
    • phpunit
    • phpcb

Install modules and plugins

Alright, we have list down the items and now lets see how to install each items.

Installation of Jenkins modules

Navigates to Jenkins » Manage Jenkins » Plugin Manager.

Under this section you’ll find four tabs, namely Updates, Available, Installed, Advanced. Select Available tab and tick the above mentioned list of plugins from the list and click on the Install without restart button.

Installation of required PHP modules via PEAR package

Please make sure that you have installed the PHP PEAR package before proceeding with the below steps.

  • phploc – A tool for quickly measuring the size of a PHP project.
    $ sudo pear config-set auto_discover 1
    $ sudo pear install
  • pdepend – Metrics analysis tool for software developed in PHP.
    $ sudo pear channel-discover
    $ sudo pear install pdepend/PHP_Depend-beta
  • phpmd – It takes a given PHP source code base and look for several potential problems within that source.
    $ sudo pear channel-discover
    $ sudo pear install phpmd/PHP_PMD
  • phpcs – It tokenises PHP, JavaScript and CSS files and detects violations of a defined set of coding standards.
    $ sudo pear install PHP_CodeSniffer
  • phpcpd – It is a Copy/Paste Detector (CPD) for PHP code.
    $ pear install
  • phpdox – It is a documentation generator for generating API documentation in HTML format, for instance, from PHP source code.
    $ sudo pear install -f
  • phpunit – It is a documentation generator for generating API documentation in HTML format, for instance, from PHP source code.
    $ sudo pear channel-discover
    $ sudo pear install phpunit/PHPUnit
  • phpcb – It is a documentation generator for generating API documentation in HTML format, for instance, from PHP source code.
    $ sudo pear channel-discover
    $ sudo pear install --alldeps phpqatools/PHP_CodeBrowser

Fixing the issue:
When you execute Build Now from the project’s menu you’ll notice that following message is displayed under Console Output section.

     [exec] Warning: require(PHPCPD/Autoload.php): failed to open stream: No such file or directory in /usr/bin/phpcpd on line 49
     [exec] Fatal error: require(): Failed opening required 'PHPCPD/Autoload.php' (include_path='.:') in /usr/bin/phpcpd on line 49

Where ever your encounter a similar error please place the following block of code on the top of the respective script. This required script can be found under /usr/bin. For example with phpcpd place the following block of code.

$path = '/usr/lib/php';
set_include_path(get_include_path() . PATH_SEPARATOR . $path);

Preparation of the build script

I used the Template for Jenkins Jobs for PHP Projects for preparing the build script. The site provides a comprehensive guide to create the build script for Apache Ant.

Elephanti the Revolutionary Lifestyle Media Network

Today social media applications plays an important role in our day-to-day activities as a result of the Web 2.0 revolution that took place in the Internet. It has revolutionized the lifestyle of almost all the individuals and business entities, for the majority of them spending at least few minutes with it has become an integral part of the day. The Elephanti, is a retail media ecosystem that aims to provide a platform for both individuals (Shoppers) and business entities (Merchants) to virtually interact with each other to buy and sells items on the go. It composed of a free Web based application for the Merchants and a free smart phone application (iPhone and Android) for Shoppers.

  • The Merchants can sign up for a free account and be able to create a virtual storefront in few minutes and manage its routine activities via the Web based console to update their profile, add products, post discounts, etc…
  • Those who are signing up as Merchants, initially selects their type of business (Single store, Chain store, Mall, Brand, Department store and Freelancer). Each type of business is modeled with an unique, customized set of features to facilitate its main line of business requirements.
  • For Merchant signing up with Elephanti, the system facilitates the merchant to describe the nature of the business and its specialization areas, such as Fashion retail, Cafes, Dinning venue, Cinema, Book stores, Services, Health and Beauty, Consumer electronic, Grocery stores, Automotive, Hotel, Travel and Tourism, Entertainment venue, etc… Each category further goes into a fine level of detailed specializations.
  • Shoppers only needs to download the app into their mobile phones to follow their favorite merchants, search for interesting place, items, create a shopping list, and many more. Using the app, they will be able to look at stores nearby and see what they have, write a review, add items to their shopping lists.
    • Shoppers will be able to look at places nearby and see what they have by check-in to the place, this provides the shopper and the shop owner a customized set of interactive features.
    • Also the Shoppers can discover Friends on the Elephanti network or sending invitations via other social media networks or via an Email and interact with each other through messaging, sharing activity updates, exchange shopping lists, uploading photo(s) to an album and tag their friends or/and places(Merchants), etc…
    • Shoppers can organize list of items planning buy just by creating a shopping lists and select nearby place(Merchant) they plans to buy it.
    • Rate a place and write a review and/or to comment them.

The main idea of Elephanti is to provide a platform for business owners to create a virtual storefront and invite shoppers to get to know about the items they sell and the discounts they offer, in the meantime the Shoppers are benefited by finding places nearby, items they sell and the discounts they offer and getting touch with their friends, plan their activities and many more.

Scheduling the Cron job task

Under General Preferences and Settings we came across a parameter to enables the cronjob tasks scheduled by the system. Open up your favourite editor (preferably vi). and issue following commands.

$ crontab -l //to list already scheduled tasks
$ crontab -e //to scheduled a new task

If this is the first time it will prompt you to select the editor, select one that preferred by you and it will open up the crontab, schedule the task as follows.

# m h dom mon dow command
MAILTO="hayeshais at" # this will fire an email upon failure to execute any of the scripts to this email address
*/5 * * * * nobody /usr/bin/php /var/www/api/cron.php
*/5 * * * * nobody wget -q -O /dev/null --user-agent=4816EC4CA293EE2EFCA2C89C88750F4A http://<>/api/cron.php

Amazon s3 with Codeignitor

When selecting the deployment environment as Amazon AWS, it comes up with a nice tool called Amazon S3 (Amazon Simple Storage Service) which can be used as a storage for static content, especially as a content delivery network (CDN).

Amazon S3 provides a simple web services interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the web, and it also consists with a set of APIs to manipulate it via most of the popular programming laguages.

In our project we maintained a separate server, accessed via FTP to store all the images used in the application. The application was developed on top of CI framework, so we didn’t had any problem communicating with the FTP server since the framework itself was geared with a feature rich FTP library. Amazon AWS environment was selected as the hosting environment. With the introduction of Amazon AWS environment we opted to use Amazon S3 as our image repositiry for the project. I found an Amazon S3 PHP library developed for CI on Git Hub. Later extended it to suite our requirements. It can be downloaded over here.

Continuous integration with Jenkins – PHP

Build automation, the practice of automating various tasks that software developers need to perform in their daily routine. These tasks usually include the compilation of source code into binary code and the running of automated tests as well as the packaging and possibly even the deployment of the resulting binaries. Although PHP is an interpreted language and does not use an explicit compilation step it is common to perform code generation or code transformation tasks during a build nowadays.

Jenkins, an Open Source Continuous Integration(CI) tool, is by far the most popular CI tool on the market. Although I’ll be focusing on a PHP project, Jenkins CI tool can be configured to used for various projects that uses different programming languages.

I got the change to setup Jenkins to monitor our PHP project and hoping to set it up for the Android and iPhone projects. The book mentioned at the end of this post nicely guides the reader towards successfully setting up and configuring a PHP project to work with Jenkins.

Please visit for a detail guide on installing & setting up the Jenkins CI Server environemnt.

Next step would be to install the required PHP Pear packages

$ sudo pear upgrade PEAR
$ sudo pear config-set auto_discover 1
$ sudo pear install

Above pear packages are required to function following plugins on Jenkins

  • PHPUnit is the de-facto standard for the unit testing of PHP code.
  • PHP_CodeSniffer is the most commonly used tool for static analysis of PHP code. It is typically used to detect violations of code formatting standards but also supports software metrics as well as the detection of potential defects.
  • phpcpd (PHP Copy/Paste Detector) searches for duplicated code in a PHP project.
  • PHP_Depend is a tool for static code analysis of PHP code that is inspired by JDepend.
  • phpmd (PHP Mess Detector) allows the definition of rules that operate on the raw data collected by PHP_Depend.
  • phploc measures the scope of a PHP project by, among other metrics, means of different forms of the Lines of Code (LOC) software metric.
  • PHP_CodeBrowser is a report generator that takes the XML output of the aforementioned tools as well as the sourcecode of the project as its input.
  • phpdox for automated API documentation generation for PHP code

Final step is to install the plugins required to integrate PHP projects for Jenkins CI Server. There are more than 500 plugins to choose from. The installation of the plugin(s) can be achieved either by using the Web-based interface or using the Jenkins command line interface, which can be downloaded as follows:

wget http://<hostname&gt;:8080/jnlpJars/jenkins-cli.jar

Install the respective plugins in the following manner, hostname – localhost

java -jar jenkins-cli.jar -s http://<hostname&gt;:8080 install-plugin <plugin name>
java -jar jenkins-cli.jar -s http://<hostname&gt;:8080 safe-restart
