Ajax responseText不起作用

In my ajax i have a var named ajax for some reason when I run ajax.respondText.

In the php code I ask it to return the username of the one log in. Well it is echoing out the name of the user but is also echoing of the header of my website in the mix as you can see here - Andrew at the bottom of the first set of code. That is the only thing that should be echoed out not the html that is ahead it.

<DOCTYPE html>

Which the response is my header.

What I am asking is to please view my code below and trying to help me understand why this is happening. I'm confused and I have tried everything that I can to fix it.

    This is coming from either of the following two includes at the top of your php script:

    include 'core/init.php'; include 'includes/overall/header.php';

    So restrict the unwanted output or file inclusion in time of an ajax call.
