Redirect, Refresh, after set time

What the standard (recommended/best) way to show a response page and then have the browser request a different page after some set time, like 5 seconds (using Codeigniter)?

jQuery

What did you Try? What did you Get? What did you Expect?

Thanks.

What if javascript is disabled?

How is js (jQuery) better/safer than the php header() function?

PHP Code:

header("Refresh:5; url={$controller}")
