You dont need to store the function inside a variable?

Inside the tutorial, we stored hello() function to a variable called $greeting. I delete the $greeting and echo the function hello() directly, the same result showed up. So why do we need to have the additional variable?

<?php

function hello($name) { if ($name == 'Mike') { return "'Mike' Hello";
} else { return "Hello World"; } }

echo hello('Mike');

Intermediate variables like $greeting are helpful for people to learn things in smaller steps but aren't needed. Your code is preferred. Good job.
