* of seconds since the epoch. In other words, you'll most likely set this
* with the time() function plus the number of seconds before you want it
* to expire. Or you might use mktime(). time()+60*60*24*30 will set the
* cookie to expire in 30 days. If set to 0, or omitted, the cookie will
* expire at the end of the session (when the browser closes).
* @param string $path The path on the server in which the cookie will be available on. If set
* to '/', the cookie will be available within the entire domain. If set to
* '/foo/', the cookie will only be available within the /foo/ directory and
* all sub-directories such as /foo/bar/ of domain. The default value is the
* current directory that the cookie is being set in.
* @param string $domain The domain that the cookie is available to. To make the cookie available
* on all subdomains of example.com (including example.com itself) then you'd
* set it to '.example.com'. Although some browsers will accept cookies without
* the initial ., RFC 2109 requires it to be included. Setting the domain to
* 'www.example.com' or '.www.example.com' will make the cookie only available
* in the www subdomain.
* @param boolean $secure Indicates that the cookie should only be transmitted over a secure HTTPS
* connection from the client. When set to TRUE, the cookie will only be set
* if a secure connection exists. On the server-side, it's on the programmer
* to send this kind of cookie only on secure connection (e.g. with respect
* to $_SERVER["HTTPS"]).
* @param boolean $httpOnly When TRUE the cookie will be made accessible only through the HTTP protocol.
* This means that the cookie won't be accessible by scripting languages, such
* as JavaScript. This setting can effectively help to reduce identity theft
* through XSS attacks (although it is not supported by all browsers).
