Questions about PHP from a n00b

[absonic]

I want to learn PHP, so i have some questions for people who are experienced with this:

Should i start with something before PHP or do i need to have some pre-knowlege, except HTML?
What are really the possibilities of PHP, what are its advantages and disadvantages? Is there a big difference between PHP and ASP?
How much time will it take to learn some basics?

And everything else you can recommend or advise to me?

afaik the large difference between asp and php are that one is free (php) and the other costs money.

They're different coding languages but likely very similar.

It's good to have pre-knowledge of any coding language before starting (they all use the same theory: loops and conditions (IFs)).

It's good to learn HTML before php, because the main use for php is to output html.

Yeah I agree with rossco, learn html first!
