Join Kevin Skoglund for an in-depth discussion in this video The operational trail, part of PHP Essential Training.
- [Instructor] In this movie, we're going to take a look…at the request-response cycle in PHP.…This cycle describes the way that a browser…and a web server communicate to process user requests.…Especially if you haven't done web development before,…it can be useful to see this cycle laid out for you.…To start with, we have our browser,…and then we have the web server.…Our browser makes a request to the web server.…That's when you type in the domain of the site.…So let's say that you type lynda.com.…It sends a request to the lynda.com web server.…In our case, that's going to be the local host though.…
And on that web server, software needs to be there…to intercept that request.…And we have an HTTP daemon called Apache that's there,…and Apache sees the request and says,…oh, okay, I'm going to see if I have a file…that will help me to respond to that request.…It then goes to the file system and looks for a file.…Let's call that file hello.php.…Apache grabs that file, and then says, okay,…I see that it has dot php at the end.…
