Random Number Script

[brown2005]

Hi, i want to have say 3 numbers

 

$number1 = RAND(1,100);

$number2 = RAND(1,100);

$number3 = RAND(1,100);

 

but none of the numbers can be the same and then i want to sort them in order of smallest frist to largest.. any help would be much appreciated

Instead of separate variables use an array, then use a loop to generate, checking if in_array, if so do again. Then when finished just sort the array!

<?php

 function rands($n,$s,$e) {
   $return = array();
   for ($i=0;$i<$n;$i++) {
     $num = rand($s,$e);
     do {
       $num = rand($s,$e);
     } while (in_array($num,$return));
      $return[] = $num;
   }
   return $return;
 }

 $rands = rands(3,1,100);
 foreach ($rands as $number) {
   echo $number . "\n";
 }

?>
