Insert variables into Header Redirect

[xProteuSx]

I am trying to modify a header redirect similar to this:

 

header("Location: index.html");

exit;

 

I would like to do something like this:

 

header("Location: index.html?user=' . $user . '");

exit;

 

Ofcourse, this does not work.  Any hints?

Ofcourse, got it solved 15 seconds after putting up the post.
