Does someone know how you do this

I'd like to generate 10 random #'s 1 thru 100 and atleast a gap of 4 apart. None can be a duplicate of the other.

Anyone know how to do that?

Thanks

Yes, Pay me

hmm basically you just need the rand(1,100) function and you test the result with your conditions...

Okay this covers your requirements, gives you 10 randomly generated numbers, at least 4 digits away from any other number it previously gave you.

$uniq=array();

function four_or_more_apart($number,$array){
$keys=array_keys($array);
for ($x=0; $x<count($keys);$x++){
if ($number-4<$keys[$x] && $number+4>$keys[$x]){
return 0;
}
}
return 1;
}

while($counter<10){
$number = rand(1,100);
if (!$uniq[$number] && four_or_more_apart($number,$uniq)){
$uniq[$number]++;
print "$number\n";
$counter++;
}
}

Kind of curious what yah need it for though...

my beautiful contribution

<?php
    for ($i = 1; $i <= 10; $i++) {
        do {
            $num = rand(1, 100);
        } while (($nums[$num] != "") ||
             ($nums[$num + 4] != "") ||
             ($nums[$num - 4] != "") ||
             ($nums[$num + 3] != "") ||
             ($nums[$num - 3] != "") ||
             ($nums[$num + 2] != "") ||
             ($nums[$num - 2] != "") ||
             ($nums[$num + 1] != "") ||
             ($nums[$num - 1] != ""));

        $nums[$num] = $num;
        echo $num . "\n";
    }
?>

I want to rotate in random sponsor galleries. I could just hardcode certain spots to be sponsors but I figured doing it random might improve my productivity? Plus new code always helps me somewhere else and I become better at php.

I appreciate the help and when I get going i'll test it out tommorow what was posted.

Thanks
