For a long time I've been using Iframes to code my websites, and although it does work properly, everyone seems to say that this is no way close to be the best way to put both pages together.

My question is what alternative do you have for it then? I don't want to put the menu on every page, since the menu changes every here and then, so what method should I opt for?

If I remember correctly there's someway to do it with PHP with an include or something.. But I don't know if I'm remembering correctly or if I'm just mixing something with something else..

Thanks for your reply.
