What’s next
You should now have a clear understanding of how PHP processes a PHP file. You should also have a basic understanding of PHP’s syntax, including how to use the PHP tags, how and when to use comments, and the importance of statement termination with semicolons.
In the next chapter, you will begin with discussions of variables, variable types, and constants. With this new knowledge, you will be able to store any information you want in the computer’s memory in order to manipulate it and send the results back to the browser, which we will discuss in the coming chapters.
