Forwarding to another PHP page

Hello, Thanks John (Holmes) for the clue on form-param-reading. Simple one, but shows I got a lot of basics to learn yet. Here I have another doubt I cant resist asking help for. What are the various ways of forwarding to another page. I tried header().. based on an example I found it in, but it doesnt work if I have done an include before calling the header. What are the other alternatives of forwarding. (I tried searching the PHP manual, but didnt find any clue. Nor did I come across any learn material which seemed to deal with this.) Thanks for all help, Ash
