Read URL - PHP

[kid A]

Hey.

Still very much a beginner, I want to make a little php snippet that does something like this:

if (currenturl = www.blablabla.com)
  goto blablabla.mysite.com

I might be able to do some of it, but how to I find out what URL the viewer has typed in? (This site has two aliases which are in fact the exact same site)

Thanks for any pointers!

$url = $HTTP_SERVER_VARS["HTTP_HOST"] . $HTTP_SERVER_VARS["REQUEST_URI"]; 

BTW The Pixies are great man, I think my fav was Where is my Mind. But it's been a while too

kid A, here's an idea...

If they are on different machines or each URL directs to a different directory, forget the URL check and just do a header redirect like so:

<?php header('Location: http://blablabla.mysite.com'); ?>

I have a few sites that have just the above in an index.php to redirect to a page on that URL and some redirect from one URL to another using the same exact thing, just change the value of Location in the header.

If they are in the same directory, your host could change the http server settings to do that or you could just use $HTTP_SERVER_VARS['HTTP_HOST'] (one of the variables Tekime pointed to) and do the logic on that, then run the code in the php block above.

If you have a possibility of people trying to go to a location below that, append the request URI on the site name. I once did this on a site that was linked to from a number of places with many files in different directories that needed to be redirected to the new server.

You see, I only have one webspace, with two domain names pointing to it. That means they both end up in the exact same index page, I wanted to take one of the urls and redirect the visitor to a subdomain I have, but it seems my webhost won't actually allow this..

Put this at the very top of the index.php page:

<?php
if ($HTTP_SERVER_VARS['HTTP_HOST'] == 'www.blablabla.com')
{
  header('Location: http://blablabla.mysite.com');
}
?>

Most excellent Sir!

I thank you.

No problem.

You could also do it in a single line by removing the '{' and '}' characters and putting the line inbetween them at the end of the if statement.

Why not just use the .htaccess file to redirect. It's faster. Check out this tutorial:

Hope it helps.
