How to generate several random numbers included in a range and whose evolution is in a range in percent?

The goal is to generate random numbers while avoiding significant discrepancies.

i tried this code but i ended up getting 0

$min=400; // starting value
$max = 600; // starting value

for ($i = 1; $i <= 1000; $i++) 
{
    $nb = random_int($min, $max);

    echo $nb . "\n";

    $percentage_min = random_int(0, 10);
    $percentage_max = random_int(10, 20);

    $min = $nb-($nb * $percentage)/100;

    $max = $nb+($nb * $percentage_max)/100;
}
