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.
Comments?

You could just put the bit of code that does the redirect above the HTML,
or use ob_start() at the beginning of your php file and
ob_end_flush() at the end, if you need to do a redirect then call
ob_end_clean() before the header() function.
and as some one else mentioned with clever use of a switch-case and
includes you can avoid header() redirects entirely.
