As other people have already said, use the header() function.
However, be sure to include exit; after you call it. I've run into
problems where it did not redirect properly if I didn't have the exit
call. This also prevents anymore of the page loading (and maybe
providing sensitive information that you don't want others to see).
Also use output buffering if you have already displayed HTML. So, an
example page:
--------------------------------------
<? session_start(); ob_start(); ?>
<html>
<head><title>Hi</title></head>
<body>
<h1>Hi</h1>
<?
if (!$_SESSION["logged_in"]) {
header ("location: login.php?redirect=hi.php");
exit;
}
?>
...
</body>
</html>

I need to "goto" different PHP pages in my web site depending on
what happens within some PHP code.
For example, if the user is not logged in when he goes to a page, I
want to 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.
