Create Random data

i want to make a script that when i visit a page named index.php it will change the test1 and toystory1 to any random alphanumeric text and visit the url, i think this is very easy but just cant figure out how. Can anyone help me pls?
Serverside or browserside(javascript), any will do.

<?php
$array = ["something","else","hello","world"];
$rand = rand(count($array));
echo $array[$rand];
?>

<?php
$array = ["something","else","hello","world"];
$rand = rand(count($array));
echo $array[$rand];
?>

I figured out that myself, but it just posts the four words given, they can easily be guessed. I want alphanumeric numbers generated which can not(unless extremely lucky) guessed. Thats where im getting stuck :-(

hers a random string generator (i did not script this)

$len = 16;
$base='ABCDEFGHKLMNOPQRSTWXYZabcdefghjkmnpqrstwxyz123456789';
$max=strlen($base)-1;
$activatecode='';
mt_srand((double)microtime()*1000000);
while (strlen($activatecode)<$len+1)
  $activatecode.=$base{mt_rand(0,$max)};
  
echo $activatecode;

Tnx bro, can you also tell me how to make a cronjob to visit refer.php in my servers public_files every 2 or 3 minutes?

why do you need to use cron ? cant you script it to make your referers do the work for you?
