<?php
$url[0] = "http://www.google.com";
$url[1] = "http://www.yahoo.com";
$url[2] = "http://www.47movies.com";
 
srand ((double)microtime()*1000000);
$randomnum = rand(0, count($url)-1);
 
header ("Location: $url[$randomnum]");
?>

Right now, I’m using this to redirect visitors to a random sponsor on a website that I recently closed down. I redirect all 404s to the index of the site using htaccess and then the index.php file contains the random redirect.

So, instead of this:

http://secure.hostgator.com/cgi-bin/affiliates/clickthru.cgi?id=bigfish

I wanted something like this:

http://www.0092ff.com/go.php?id=hostgator

I found a ton of scripts that would allow me to do this, both free and paid versions, but I couldn’t find exactly what I wanted. I tested out a couple free scripts, but I didn’t like the way the links were created.

After a while I stumbled upon this simple PHP code that would allow me to do exactly what I wanted to do, without all the bells and whistles.

Create a text file and copy/paste the following code:

<?php
  $id = $_GET['id'];
  $links = array(
    "google" => "http://google.com",
    "yahoo" => "http://yahoo.com",
    "wikipedia" => "http://wikipedia.org"
    );
 
  header("Location:".$links[$id]);
  exit;
?>

Then, just change the names and link codes to fit your needs. Save the file as “go.php” and then set up your links like this:

http://www.yourdomain.com/go.php?id=google

http://www.yourdomain.com/go.php?id=yahoo

http://www.yourdomain.com/go.php?id=wikipedia

If you want to add more links, just copy/paste another line in. You have to pay attention to where your commas are placed though.

It doesn’t get any easier than that!

<?
$random_url = array("http://www.google.com/1",
                    "http://www.google.com/2",
                    "http://www.google.com/3",
                    "http://www.google.com/4",
                    "http://www.google.com/5");
 
$url_title = array("Google Link 1",
                   "Google Link 2",
                   "Google Link 3",
                   "Google Link 4",
                   "Google Link 5");
srand(time());
$sizeof = count($random_url);
$random = (rand()%$sizeof);
print("<a href="$random_url[$random]">$url_title[$random]</a>");
?>

Then, insert the following code in your php file where you want the link to appear.

<?php include ("random.php"); ?>

Enjoy!

After talking to the script creator for awhile, we figured out that this issue was caused by my .htaccess file and he provided me with a much better method of using the 301 redirects.

This was my old method:

RewriteEngine on
Options +FollowSymLinks
RewriteCond %{THE_REQUEST} ^.*/index\.html
RewriteRule ^(.*)index.html$ http://www.bfxmedia.com/$1 [R=301]
RewriteCond %{THE_REQUEST} ^.*/index\.htm
RewriteRule ^(.*)index.htm$ http://www.bfxmedia.com/$1 [R=301]
RewriteCond %{THE_REQUEST} ^.*/index\.php
RewriteRule ^(.*)index.php$ http://www.bfxmedia.com/$1 [R=301]
RewriteCond %{THE_REQUEST} ^.*/index\.shtml
RewriteRule ^(.*)index.shtml$ http://www.bfxmedia.com/$1 [R=301]
RewriteCond %{THE_REQUEST} ^.*/index\.asp
RewriteRule ^(.*)index.asp$ http://www.bfxmedia.com/$1 [R=301]
RewriteCond %{THE_REQUEST} ^.*/index\.aspx
RewriteRule ^(.*)index.aspx$ http://www.bfxmedia.com/$1 [R=301]
RewriteCond %{THE_REQUEST} ^.*/index\.cfm
RewriteRule ^(.*)index.cfm$ http://www.bfxmedia.com/$1 [R=301]
RewriteCond %{THE_REQUEST} ^.*/index\.pl
RewriteRule ^(.*)index.pl$ http://www.bfxmedia.com/$1 [R=301]
RewriteCond %{THE_REQUEST} ^.*/default\.asp
RewriteRule ^(.*)default.asp$ http://www.bfxmedia.com/$1 [R=301]
RewriteCond %{THE_REQUEST} ^.*/default\.htm
RewriteRule ^(.*)default.htm$ http://www.bfxmedia.com/$1 [R=301]

Once we figured out the issue, he provided me with this:

RewriteCond %{THE_REQUEST} !/links/ [NC]
RewriteCond %{THE_REQUEST} ^.*/(index|default)\.(s?html?|php|aspx?|cfm|pl)
RewriteRule ^(.*)(index|default)\.(s?html?|php|aspx?|cfm|pl)$ http://www.bfxmedia.com/$1 [R=301,L]

He added the RewriteCond with the “links” directory and he condensed the line with all the file extensions down to one line. Now, I’ve got to change all my .htaccess files to this new streamlined version.

If you’re looking for a good (free) link trade script, you need to get LinkEX.
