help with the random code

[sabret00the]

PHP Code:

<?php

          echo("[high]REQUESTS: [/high]");

            $rand[0]=" ";
            $rand[1]=" ";
            $rand[2]=" ";
    
            $entry = rand(01,19);
            
            echo("$rand[$entry]");
?>

how would i get this to display 5 of the rands at a time and make sure it doesn't repeat any (display the same one twice.

Only limit the rand to 5.
rand(1,5)

ok, so cos it's for my site, it will display 5 of my requests at a time randomly not repeating any of em?

If you're lucky, it wont repeat.

But after properly reading what you want, it would be easier (and probably the only way) is to use the DB at the backend

Heh, never knew you could do that.

count function counts the number of items in an array

well I knew that I just didnt know you could use it in rand

[Dean C]

An arguement to a a function can be a function you know

I once saw somewhere [I think on php.net] a way to prevent a rand() function from showing the same thing twice...Took a lot of code though.
