I don't think you can split the cookie-line on ";", since the semicolon is allowed withing double-quotes, eg.:
Set-Cookie: COOKIE1="a;b;c"; path=/xyz; Max-Age=100

Here's a good way to get cookies from a page and then resubimit the data to that page (or acess any other page using the cookies gotten).

<?php

//SOME DATA TO POST
$postData = array
(
'user' => $login,
'pass' => $pass
);

//FIRST POST
$post1 = http_post_fields('http://example.com', $postData);

//GET THE COOKIES STORED TO THE ARRAY $cookie
preg_match('/Set-Cookie: (.*)\b/', $post1, $cookie);
$cookie = (array) http_parse_cookie($cookie[1]);
$cookie = array( 'cookies' => $cookie["cookies"]);

//POST DATA NOW WITH THE COOKIE
$post2 = http_post_fields('http://example.com', $postData, array(), $cookie);
?>

                        $line = preg_replace( '/^Set-Cookie: /i', '', trim( $line ) );
                        $csplit = explode( ';', $line );
