Help in migrating a site to PHP from HTML

[Crazy Pete]

Hey folks,

I did a search on this and couldn't find any relevant threads, and I apologize if this is in the wrong section so feel free to move it.

What I need help with basically is in how to go about converting my current static (HTML) website into a more dynamic PHP/MySQL-driven site.

My main problem right now is if I want to add anything to the site, for example any links to another site page off the main one, I have to update 20 pages instead of just inserting one line.

Basically I need to know how to get started in converting my site over to PHP and how much work is involved in it, along with any good resources you'd want to pass along. Thanks very much for any help!

On a side note, I would publish the URL here for people to get an idea of what I'm doing, but I can't right now because we're in the process of switching hosts, so it most likely wouldn't work.
