Nope, it is very related and for all we know he maybe didn't even know you can do it with html and javascript and thus asked the question as he did. Maybe he doesn't know PHP and maybe rather don't wanna use or learn it just for that, but only asked it in the way he did because he assumed it was only possible with PHP
(you would be surprised in how many people ask stuff like this in this way as they don't know which alternatives exist; or asking something slithly differentl/or too specific than what they actually mean, unwillingly).

Also the post is very relevant for anyone else who is searching for the subject and/or have the same questions and/or thought-process as I just described. For this, the post isn't only for answering his question, but also for answering the questions of people who might come across this thread (and maybe even don't know about PHP and/or javascript and/or the difference, etc).
(is also part of anticipating questions)
