PHP in OSX not saving cookies?

Hi. Im using Mac Leopard. I am using the PHP that comes default and the default Apache2. I have having some trouble with saving cookies using Curl in PHP. I used curl_setopt($ch,CURLOPT_COOKIEFILE,$cookie) ($cookie being the path to the folder I want my cookies to go and I look and there are no cookies in my folder. I also tried COOKIEJAR and it still doesn't work. I don't know if this is a Mac thing because when I had Linux Ubuntu I had no problems. If someone could help it would be appreciated.

Can't say I know the answer. One guy here mentioned he didn't set privileges properly on the directory. There are also some sample coding there too.
