Mind if is why?

Maybe someone can suggest an alternate course of action if you can't do it directly using cURL.

Does your PHP script have write permissions for that directory and file?

Have you tried writing to a file located relative to the script?
(eg. curl_setopt($ch2, CURLOPT_COOKIEFILE, "my_cookies.txt");

Subject: Retrieving cookies

I'm very new to Curl, but figuring it out pretty quickly.

A problem I'm running into is that I need to retrieve a cookie that is set by the page after I do a Curl POST submit to it.

Now I've read thru all the documentation and all I found was mention of CURLOPT_COOKIEFILE and then some examples with CURLOPT_COOKIEJAR. Now the former seems to be entirely related to sending a file with the cookie information you want to pass to a Curl session and the latter seems to be something where you can store the cookies(despite the lack of documentation on this on the PHP site).

I would prefer that I could set a variable to the cookie(s), but from a bug I read on the PHP site, it seems this is not possible yet.

So I messed around with this a bit and with the intention that any
cookie information would be written to the filename(/tmp/my_cookies.txt) I sent CURLOPT_COOKIEJAR to so I then
could read the information out of the file. However, the file was never written.

curl_setopt($ch2, CURLOPT_COOKIEJAR, "/tmp/my_cookies.txt");
curl_setopt($ch2, CURLOPT_COOKIEFILE, "/tmp/my_cookies.txt");

It seems the only way I can grab the cookies that are set by the page
would be write a regular expression to parse the header information
that is returned by the curl_exec cmd.

So in all,

1) Is there no way to get the cookie information that is set by a curl session into a variable?
2) If 1 is not possible, can you write it to a file? If so, then what
am I doing wrong.
3) If 1 and 2 aren't possible or it makes sense, should I just parse
the header information?

Thanks for the help,
