variable with random number

lukeurtnowski

this is what im trying to do, I'm trying to use php to redirect the user to another php page (main.php) and I'm trying to append a variable in the URL thats value will be a random number between 1-3, thanks for your help...

<?php
$random = (rand()%3)
header("Location: main.php?'$random'"); /* Redirect browser */
exit;
?>

<?php 
$random = rand(1,3);
header("Location: main.php?variable=".$random); 
?>

thank you, do I put that in the body, head or before the <html>?

Since you're using a header redirect, you don't need any other tags on the page.

I got this error though
Warning: Cannot add header information - headers already sent by (output started at /home/domains/lukeu/lukesplace.com/otto/index.php:1) in /home/domains/lukeu/lukesplace.com/otto/index.php on line 3

Just to slim it down, this should be your whole entire page

<? header("Location: main.php?variable=".rand(1,3)); ?>

are u trying to send it from a page included by another? That can cause ur error message.
