Question

well i have a use for rand();
I need to rand from 1 to x amount 4 times and make sure the value will not return.

This is my code corrently:

 $Count = 15;
 $secondstage = '';
 $arrayindex = '';
 for($i=1; $i<5; $i++){
    $arrayindex = rand(1,$Count);
    if($secondstage == $arrayindex){
        for($b=1; $arrayindex == $secondstage; $b++){
            $arrayindex = rand(1,$Count);
        }
    }
    $secondstage = $arrayindex;
    echo $secondstage;
    echo '<br>';
 }

Am I having some logic mistake here? I thought of maybe using while but for should also work.

So basically you want 4 random non-repeating numbers between 1 and 15, inclusive? You’re using way too much code for that. A simpler version:

$numbers = array();
do {
   $possible = rand(1,15);
   if (!isset($numbers[$possible])) {
      $numbers[$possible] = true;
   }
} while (count($numbers) < 4);
print_r(array_keys($numbers));
