Me done that hundreds of times.

CURLOPT_COOKIEFILE is for *reading* cookies, so I should hope the file isn't
written to because of this use.

Yes, passing file 0 looks very odd. I would say a file name needs to be a
string. Or is that a string in PHP?

You tried reading the docs?

Well, that's good for you, but trying FOLLOWLOCATION on a site that doesn't
use Location: isn't very productive!

I don't think I follow you here.

Yes it is.

No. The request is made by curl_exec(), not previously. The curl_setopt()
calls are just for setting options.

I get your idea, and to repeat what I use to say here, with libcurl itself
you can do repeated requests using the same libcurl handle which makes things
like this easier without the need of temporary file storage. The PHP/CURL
module is however not written to allow that practise.

You need to improve the PHP/CURL code first, or stay with the more simple
approach of mulitple init/setopt/exec/close iterations.

setopt() sets options. The order is only important if two setopts set the
same option to different values.
