How do I pass a value into a header() function?

Question

I have to redirect users to different pages. So here is what I have now.

header('Location: http://www.example.com/$confirmpage')

But it doesn't work. It redirects them to http://www.example.com/ $confirmpage (value not retrieved.) and gives 404 error.

When I use

echo "<script>document.location='http://www.example.com/$confirmpage';</script>";

It works.

But I have to use header() function for some reasons.

Answer 1

header("Location: http://www.example.com/$confirmpage")

If you want to refference variables in php strings, you have to use " instead of '
