help with the random code

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)

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

Tut tut ;):

PHP Code:


		
			
<?php



          echo('REQUESTS: ');



            $rand[0] = '';

            $rand[1] = '';

            $rand[2] = '';

    

            $entry = rand(01, count($rand));

            

            echo("$rand[$entry]");

?>

count function counts the number of items in an array :)

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.
