Random URL Redirection

[Anon]

I just want to make a simple php3 script that will redirect to another random page. Sort of like the one at http://www.newgrounds.com/random_page.php3. I have been trying unsuccessfully for 3 days to find a script/find out how to make a script like this. If anyone could help it would really be appreciated.

A simple example to put you on a track.
- You feed an array with the address you want to redirect.
- Choose a random array element.
- Redirect to that address

A sample of code.

<?

// addresses are stored in a file. 1 address per line

$adds=readfile("addr.lst");

srand((double)microtime()*1000000);
$addrNo=random(1,count($adds)) -1 // First element is index 0

// Redirect to the random page
$redir=$adds[$addrNo];
header("Location: $redir");

?>

You can do all this in 2 steps
<?

// addresses are stored in a file. 1 address per line

$adds=readfile("addr.lst");

$addrNo=random(1,count($adds)) -1 // First element is index 0

// Redirect to the random page
srand((double)microtime()*1000000);
header("Location: {$adds[rand(1,count($adds)) -1]}");

?>

Try something like this:

<?
srand ((double) microtime() * 10000000);
$input = array ("http://www.php.net/", "http://www.zend.com/", "http://px.sklar.com/", "http://php.codebase.org/", "http://www.phpwizard.net/");
$rand_keys = array_rand ($input, 1);

  header("Location: $input[$rand_keys[0]]");

?>

I'm not too sure if this code will actually work since I'm not in front of my server and can't easily access it. It is adapted from an example in the array_rand() section of the PHP manual.

Hope this helps!!!!!!

Opps.......🙁

Sorry 'bout the double posting. I s'pose I should have had PHPBuilder.com as one of the example sites to eh?🙂

hey, i was thinking about this and JB posted before me so i'll post anyways 😉 it's good to see multiple versions :

<?
$link[0] = "www.theprojects.org";

$link[1] = "www.somesite.com";

$max = count($link)-1;

srand((double)microtime()*1000000);
$rand = rand(0,$max);

header( "Location: http://$link[$rand]");
?>

i am learning to make better arrays so the above isn't optimal but should be very clear in what it does for a newbie such as us. i like how JB's array doesn't require link[n]'s and will learn from this, thanks.

good luck!

JB, your script was too hard for me. I a really, really big beginner. And Geoff, I got this error on your script:
Fatal error: Call to unsupported or undefined function array_rand() in /www/wickedjuggalos/random_page.php3 on line 4

ryan,
that may be because you are on a php3 server? as rand_array is a php4 function.

That one worked. Thank you VERY much.

Oh. I didn't know that. I guess thats why it didn't work. And thanks for everything.
