未定义的变量 - 但包含在另一个变量中

I have header.php with the following code:

<?php include('config.php');?>

<body>

<header>
    <nav>
        <ul>
            <?php
                echo "<li><a href=\"$root/index.php\">Home</a></li>";
            ?>
        </ul>
    </nav>
</header>

This is my index.php:

<?php 
   include('include/head.php');
   include('include/header.php');
?>
    <h1>whattup</h1>
    </body>
</html>

Since I included config.php in the header.php which contains a $root variable, I would assume it is also automatically included to the index.php. Why isn't this the case? The solution that works is to include the config to index.php but I feel like that is redundant if I already included that into the header.php
