I have a php file in a folder with a script like this:

PHP Code:


			
<?php
if($_SERVER['HTTP_REFERER'] != "")
{
$random = rand(0, 2);
$aff_array = array("http://www.website1.com",
                  "http://website2.com",
                  "http:/website3.com");
header("Location: ".$aff_array[rand(0,2)]);
exit();
}
?> 
<html xmlns="http://www.w3.org/1999/xhtml">
<head>

Basically if there is a referer (visitor came from another website) then they are redirected randomly to 1 of 3 of my other sites above website1, website2, or website3. If they don't have a referer then they are not redirected and stay on the same page (reason for the html code below the php script).

What I'm wondering is when the visitor is redirected to website1, website2, or website3. Is it possible to have the same type of script as above but, in reverse? If the visitor has a referer they stay on the same page and if they don't have a referer then they are redirected to another different webpage? say for example website4.com ?

Thanks

First off, not sure why you set the $random, when you end up just using the formula later on...

At any rate. So, you have a page set up, so that when you go to it with no referrer, it shows the page as normal. But if you visit the page with a referrer, it will automatically redirect you to another page... Correct?

PHP Code:


			
<?php
if($_SERVER['HTTP_REFERER'] = "")
{
$aff_array = array("http://www.website1.com",
                  "http://website2.com",
                  "http:/website3.com");
header("Location: ".$aff_array[rand(0,2)]);
exit();
}
?>

With the above code, if there was NO Referrer it would direct them to another page. However if there was a referer it would show the HTML after the PHP script. Is that what you where looking for? (Note all I really did was change the NOT EQUAL to (!=) to EQUAL (=).)

Thanks for your reply.

"So, you have a page set up, so that when you go to it with no referrer, it shows the page as normal. But if you visit the page with a referrer, it will automatically redirect you to another page... Correct?"

Yes, that is how the code works now. It already works fine like that.

Although what I'm wanting to know is, when the user is redirected (if they have a referer) just like how it works now. When they get to the next page (the redirected page) is it possible to setup the same script but, in an opposite manner. So, on the next page (the redirected) page there is a code that will keep them on this page if there IS a referer and if there is no referer it will redirect them to another webpage.

So, I'm wanting to setup the same type of code on the redirected page as on the 1st page but, in reverse.. does that make sense?
