Now that you have worked hard to connect PhpStorm and Phing, you must know what drives Phing. What is it that allows you to do wonders with Phing? What is it that makes your life easier and makes adherence to the principles of software engineering easier? The name you had to think of was build file. Yes, it is the build file that controls the behavior of Phing. Yes, using build file, you can do wonders with Phing. Yes, using build file, you can perform tasks in a clean way—thus adhering to the principles of software engineering.
