-I recently had the need to extract the value of a Set-Cookie response header in PHP. Google lead me [`http_parse_cookie`](http://php.net/manual/fa/function.http-parse-cookie.php). Unfortunately, `http_parse_cookie` requires `pecl_http` which isn't available with PHP out of box, and is a pain to install.
