// Retrieve headers along with the response
curl_setopt($ch, CURLOPT_HEADER, 1);
$result = curl_exec($ch);

// Extract cookies using regular expression
preg_match_all('/^Set-Cookie:\s*([^;]*)/mi', $result, $matches);

// Convert cookies to an array
$cookies = array();
foreach ($matches[1] as $item) {
    parse_str($item, $cookie);
    $cookies = array_merge($cookies, $cookie);
}
