how to use biasedNumberBetween faker? [closed]

Question

I am trying to get a number between 1 to 6 with more chances to be close to 1.

i have tried this:

<li>{{Faker\Factory::create()->biasedNumberBetween($min = 10, $max = 20, $function = 'unbiased')}}</li>

What i am trying to do is to generate a number from 1 to 6 rand(1,6); but make the numbers be closer to one as the lower numbers will have more weight than the others.

Answer 1

Something like this ?

<?php
function weightedRand($min, $max, $weightedMax) {
$arr = array();
for($i = 0; $i < 10; $i++) {
    $arr[] = rand($min, $weightedMax);
}
$arr[] = rand($min, $max);
return $arr[rand(0,10)];
}

echo weightedRand(1,6, 3);
?>

numbers below 4 will now be more likely than numbers above :)
