Looking at the php documentation on setting a cookie I see that I can set an expiration date for the cookie. You can set the cookie to expire at the end of the browser session or at some time in the future but I do not see a way to set the cookie to never expire. Is this even possible and how is this accomplished?

All cookies expire as per the cookie specification, so this is not a PHP limitation.
Use a far future date. For example, set a cookie that expires in ten years:
setcookie( "CookieName", "CookieValue", time() + (10 * 365 * 24 * 60 * 60) );
Note that if you set a date past 2038 in 32-bit PHP, the number will wrap around and you'll get a cookie that expires instantly.
