First, You need to put the script in the tags, instead of above the DOCTYPE. Try this

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>My website</title>
<link rel="stylesheet" type="text/css" href="/assets/css/main.css" />   
<?php
if (count($_POST)) {
   msg('TEST!!!!!');
}
?>
</head>

After that, there might be more problems.
