PHP vs. ASP

[amo]

I know the obvious difference is that asp is for NT servers and PHP is primarily *nix, but I've also heard that the two languages are almost exactly the same.

With that said, can small asp scripts be ported to php w/o much difficulty? (I know this is very vague, but I just need a vague response :) )

Try this on for size ;)

I've never used anything like that. Do they work well?
I'd imagine they do fine for regular syntax, but what happens when your code starts to get more complex? (stuff like CDONTS or DB connections or COM objects)
