Chapter 1. About TYPO3 API

Let's get a picture of TYPO3 API before we start to talk about extension creation. There are a lot of files, functions, and function groups in TYPO3 API. Beginners can easily miss the function they should use in a particular part of the code.

This chapter is going to discuss TYPO3 API. We will not go into the details, but will provide pointers to where developers can look. The best way to read this chapter is to keep a copy of each discussed PHP file and read function description inside that file along with the description mentioned in the book.

After completing this chapter, the reader will have a general picture of TYPO3 API, and will be able to find the necessary functions in the API.
