Hey guys!I have the following error and I am not sure why because I thought that we could include the header.php and footer.php file at the top?

I will include both my footer.php file and level.php:

This is my footer.php file:

The error message is pretty explicit.  Your script in total has apparently output something prior to the call to the header function.  Look for a blank line outside of your php code block or an echo/print statement.  You cannot output anything to the client before calling header.  As with any php error message, ;ook at the given line number for a clue.

As ginerjm mentioned, nothing can be outputted to the screen before calling the header() function. Note that your level1.php script has several lines of output at the top. The script will need to be rewritten so that you do all your processing at the top. Then all of the output would be done at the bottom of the script.

In what tutorial did they tell you to duplicate the opening and closing HTML tags? All these tags and the closing counterparts only go in a document ONE time.

 

<!DOCTYPE html>
<html>
<head>

Hey piano0011!

Browsers tend to do all sorts of things to try and present something, even when the input is mangled or malformed HTML.  

Benanamen pointed out your issue:  You are repeatedly injecting full HTML documents into the same HTML document.  

Candidly, the old header.php, footer.php paradigm is limiting in many ways.  For example, for SEO purposes the single most important thing for your pages is the Title.  The title tag needs to be descriptive, AND your page should also have an h1 that duplicates the title.

If you have a static header.php script that includes the header, you will inevitably need a way to inject the title in some way.  

But lets forget about that for a moment and just get you to a place where you understand the basics of HTML/HTTP and how PHP plays with these.

With PHP, as soon as you start output which in your level1.php file is started immediately due to the fact that you begin with an HTML block! the HTTP headers get sent to the client.  This is rarely what you want in a PHP application.  

There are many things you might want to do first, like setting up a php session, querying your database, or checking for things in $_SERVER or $_COOKIE.  Don't start your scripts with an HTML block as you are doing in level1.php!

I don't know what is in header.php, but as Benanamen explained, your footer.php should not have the same repeated html, header etc. tags.  Typically a footer only has a navigation menu, copyright notices and perhaps some included social media buttons along with possibly some included .js scripts.  

I would highly encourage you to familiarize yourself with the Chrome dev tools and in particular the network tab.  This will help you explore the underlying HTTP protocol and aid your understanding of how your PHP scripts in conjunction with the web server actually respond to browser requests.
