Reflection in PHP

This Kata Series explores a core API in PHP called Reflection which allows a developer to reverse-engineer classes, interfaces, functions, methods and extensions. It is assumed that the user undertaking this Kata Series is already familiar with both functional and object-oriented programming in PHP. A good indicator that you are ready for this Kata Series is if you are able to complete at least 6 out of 8 topics/Kata in my PHP Functions series without hesitation and are at least moderately familiar with all the topics covered in the first 7 Kata in my Object-Oriented PHP series. Certain Kata in this Series may also require slightly more advanced OOP knowledge such as the awareness of what an interface is, but if such extra knowledge is required, it will be mentioned under a "Prerequisites" subtitle.

Most Kata in this Series will consist of two main parts - a "Lesson" and a "Task". However, unlike either of "Object-Oriented PHP" and "PHP Functions", the "Lesson" will only teach the fundamental concepts required to understand the "Task" presented in each Kata. In most cases, you will be expected to look up on the official Reflection documentation in order to figure out the details of how to actually complete the Kata "Task" (e.g. which methods to call or even what class to use!). If you are still in doubt after referring to the official documentation, you are strongly encouraged to conduct your own research and use whatever resources are available to you on the Internet or otherwise.
