I need to "goto" different PHP pages in my web site depending on what

For example, if the user is not logged in when he goes to a page, I want

send him to a LOGIN page.
I've have everything working fine, using the following Javascript code:
$location = 'login.php';
echo "<script language='javascript'>\n";
echo "document.location.href = '" . $location . "';\n";
echo "</script>\n";
I also played around with using the header("location: ...") function.
I understand that the header() function must be issued before any HMTL is
output.
But I'm not sure about the Javascript code. In every instance in my code,
I
use the Javascript before any HTML - this type of action normally occurs
in
PHP code called via a form POST.
I presume that the Javascript code really does the same as the PHP stuff,
and thus must obey the same rules, but I'm not sure.
Comments?

There's a difference in them, as the php header function defines the
redirect in the header, meaning that all body is not even parsed. And it
works also if javascript is disabled.
I prefer the header function, but if you already have data parsed, the
javascript could to the job, but even then it needs to be inside the <head>
tags i believe, or else it won't get automatically executed.
