Include HTML with variables

[arggg]

I have an external html that is a form. the Values of the form elements have <?= $results['Name'] ?> type information however with file_get_contents in the main php file that then stores the contents to a variable so it can return ALL the data is not completeing the variable processing of the HTML FILE.

For example the values that have $results in them are just displaying $results instead of the actual database information.
Does anyone know of another way to import a false parse the php variables in the external file then set it as a variable ($content) then return $content?
the function is.

    function editUser()
    {
        global $db, $error,$func,$login;
 
        $sql = "SELECT * FROM users INNER JOIN tsms WHERE id='".$_REQUEST[2]."' AND tsms.uid=tid";
        $sql = $db->query($sql);
        if ($results = $db->fetchArray($sql))
        {
            $content = file_get_contents('./includes/editform.html');
        }
        else 
        {
            $error->addError("INVALID USER","CANNOT FIND USERID ".$_REQUEST[2]);
        }
        return $content;
    }
