Random

[dc_jt]

Hi

 

Ive got numbers 1 - 6.

 

I want to echo out 3 of these numbers at random but the same number cant appear twice.

 

E.g

 

1,3,5 would be correct

 

1,4,5 would be incorrect.

 

How would I do this?

Thanks

<?php

  $n = array();
  for ($i = 0; $i <=3; $i++) {
    $tmp = rand(1,6);
    if (!in_array($tmp,$n)) {
      $n[] = $tmp;
    }
  }

  echo implode(' ', $n);

?>

Sorry, thats way off. Half asleep here.

 

<?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(3,1,6);
  echo implode(' ', $rands);

?>
