Redirect and Random Number Generator

[chapperzUK]

I'm trying to create a php page that creates a random number and then redirects to another page based on that number.

So if the random number is 1, the redirect.php redirects to www.google.com,
if it is 2 then it redirects to www.yahoo.com etc.

I've tried this and failed many times.

Thanks.

<?php
$rn = rand(0,1); // first argument is minimum (inclusive), then maximum (inclusive).
$arr = array("http://www.google.com/","http://www.yahoo.com/");
$random_page = $arr[$rn];
header("Location: {$random_page}\r\n");
?>

Just set the rand() arguments and the array values.

Thanks, sorry I'm a bit new to this. Where do I put it?

Wherever you're generating your random URLs. If you do more processing before actually doing the redirect, put it before the header() line. You'll need to modify the highlighted parts:

$rn = rand(0,1); // first argument is minimum (inclusive), then maximum (inclusive).
$arr = array("http://www.google.com/","http://www.yahoo.com/");
$random_page = $arr[$rn];

For the highlighted "1", just put the number of pages that you will, minus one. For the array, just put a list of pages to redirect to. The URL of the random page is stored in $random_page, and you can redirect using the Location: header, like that in the code I posted.

it would be easier to do this instead, so that you need only modify the array:

<?php
  // Array of URLs
  $urls = array("http://google.com", "http://yahoo.com");

  // Pick a random URL from the array
  $page = $urls[rand(0, count($urls) - 1)];

  // Redirect
  header("Location: " . $page);
  exit;
?>

chapperz, assuming you're just linking to this script and it doesn't do anything else, then you just need to create a new PHP file (randomURL.php, for example), and then put that code inside of it. then, whenever it loads it will pick a random URL from $urls and redirect to it.

Thanks .

I'm pretty new to PHP coding. What should the PHP file look like?

[minitech]

Exactly that. If you copied + pasted that code into a blank PHP file, it would work.
