Can you explain please, is that a comment on the suggested tutorial, or is there something I should be aware of, thanks.

This isn’t the recommended way to check for a post submission.

You are already doing it correctly here.

Assigning a variable to another variable without processing or changing anything would be considered a pointless waste of code.
Doing something like:-

$word = trim($_POST["word"]);

or

$word = myValidationFunction($_POST["word"]);

Would make more sense, otherwise just leave it as $_POST["word"] if you are not going to change anything.
