I think the following line in this tutorial page is incorrect where it says "$hello file":
An important point to note is that the template file has the same scope as the mod_helloworld.php file. What this means is that the variable $hello can be defined in the mod_helloworld.php file and then used in the $hello file without any extra declarations or function calls.
My guess is that it should be "helper.php file", but since I'm going through the tutorial for the first time I'm not 100% certain.
