Thanks a load, wirehopper...just what I needed...informative and complete answer
Hmm, using ur answer as a checklist, lemme see:
1. Already following all that, as I don't want to break my head in 2 when I come back a month later and don't understand what I did.
2. That is a virtue? I mean I would rather prefer <?echo 'Hello world!'?> to the more complicated <?= "Hello World!"?> and other weird shortcuts used by those who call themselves uber coders. Nice to know I'm doing the right thing!
3. Hmm, reuse is something I do practice, as I am pretty lazy. Another good thing I do...
4.Hey that's a new thing there. I usually wrap all my HTML inside an echo. I gotta learn how to do what you said.
5. Yes. Done. I love outputting witty and entertaining error messages when they do happen.
6.Hmmmmmm....secuuurityy....the one thing I can't seem to get my head around. I'll have to put in more research time into this one I guess.
7.Of Course.
8.Hmm? I didn't get you wid that...
9.

I dunt know linux yet. Problem it ees. However, can you explain with an example as to where linux scripting wud fit into, say, a php project of classified ads?
10 & 11. U have once again left me in the abstract with those. How do we define 'efficient' logic and its 'inefficient' counterpart? And what's a footprint?
Thanks again for the reply, wirehopper, and everybody else...
