How do you use echo in php to print text in html?

I am attempting to use php to print out a line of text onto a html file, but when I run the html, it merely prints the word undefined. How can I fix this? Here is the code:

HTML:

<html>
<head>
</head>
<body>
<script type="text/javascript">
var xmlhttp=new XMLHttpRequest();
var textinhtml=document.createElement("div");
var text=document.createTextNode(xmlhttp.open("GET","http://mikeyrichards.bugs3.com/test.php",true));
textinhtml.appendChild(text);
document.body.appendChild(textinhtml);
xmlhttp.send();
</script>
</body>

PHP:

<?php
echo "Hello, World"
?>

As commented your usage of XMLHttpRequest is wrong, you should check online example of it, like this example from the mozilla dev network

Adapted to your script :

<script type="text/javascript">
   var xmlhttp=new XMLHttpRequest();
   xmlhttp.onload = function() {
       var textinhtml=document.createElement("div");
       var text=document.createTextNode(this.responseText);
       textinhtml.appendChild(text);
       document.body.appendChild(textinhtml);
   }
   xmlhttp.open("GET","http://mikeyrichards.bugs3.com/test.php",true)
   xmlhttp.send();
</script>

this script does not account for the errors from the request. Please read the documentation to handle them.
