Rendering the Web Page

It’s time to pull all of the above episodes together and give you an overview of how the web page is rendered, meaning it is built and sent out to the browser. You will learn about the full round-trip including how PHP immediately renders out as the HTML is being built. You’ll also learn about how the browser requests the resources from the web server. Remember, these files are stored on the web server’s hard drive(s). The browser can cache these resources to save page loading on subsequent visits. But on the first visit, the browser has to ask the server for the files.

Let’s talk about this to give you a big picture view of the entire web request-to-page cycle.
