Continuous integration

The idea behind continuous integration is to bind together the building, testing, and releasing processes in an easy-to-oversee manner. As we mentioned before, the notion of building is a bit of a specific one when it comes to PHP, given the interpreted nature of the language itself; we are not talking about compiling code here. With PHP, we tend to relate it to various configurations required by our application.

That being said, some of the strong points of continuous integration include the following:

• Automated code coverage and quality check through static code analysis
• Automation by running after each developer code push
• Automated faulty code detection through unit and behavior testing 
• Reduced application release cycle
• Increased visibility across project

There are a dozen of continuous integration tools to chose from, some of which include the following:

• PHPCI: https://www.phptesting.org
• Jenkins: http://jenkins-php.org
• Travis CI: https://travis-ci.org
