problem is very very simple; simply swap the code order
<?php
// add in logic if you want
header('Location: ' . 'http://auction.househops.com/index.php');
echo '<h1>Redirecting... Please Wait</h1>';
?>
but please expand including a link to where you are redirecting too.
The apache default pages are very very good and include the status
(+code) and a short note:
302 Found
The resource you requested has been found <here-link>
note: that's not the exact text, but you get the idea.

no no no; (sorry ash) but HTTP is there for a reason and it accommodates
everything we need + can be used for *any* file (how do you javascript
redirect an image for instance) - all catered for.
always remember that the web is built on http & hypermedia (media w/
links); it's the whole reason we have a web, is the web and works v well.
also worth noting that apache foundation formed by roy t fielding, same
man who wrote rest, which is the model for http, and check the name at
the top of http, roy again; he's put in tonnes of work and guidance to
the full net, and of course apache http server itself - when in doublt
just copy apache and read the rfc + dissertation.

because user agents MAY redirect, they don't have to - and when its a
post or such like they may want to make the choice of whether to proceed
or not; likewise from https to http and so forth.
http rfc is pretty clear that with every 3xx & 4xx status could you
should give a reason as to why and also give possible actions the user
an take next - preferably as hypermedia links to make it properly resftul.
"307 Temporary redirect, redirecting you to <xxxx> click the link if you
are not automatically redirected".
