header（）函数中的属性

Question

Is there a way to send some attributes when redirecting with header() function?

I would like to send some error message when redirecting(PHP5).

I know that I could just show error page for a 5 seconds or so and then redirect. Or redirect with query in link, but that's not the point.

Somethin like this:

header('Location: /mvc/index.php', $some_attributes);

and how to get them on index page?

Btw, I think that Location can't be relative, am I right?

Answer 1

A URL is a URL. You can pass data in it the same way as any other URL (i.e. encode it in a query string then read them with $_GET).

Btw, I think that Location can't be relative, am I right?

Yes. Most browsers will perform error recovery on relative URIs in location headers (Lynx will do so while flashing a warning at the user), but the specification requires that they be absolute.
