<?php function weight($array) { $rnd = mt_rand(0, array_sum($array)); foreach ($array as $k=>$v) { if ($rnd <= $v) { return $k; } $rnd -= $v; } } $weights = [100, 200, 1000]; $values = array_fill(0, count($weights), 0); for ($x = 0; $x < 1000; $x++) { // at the position returned by the weight function, +1 $values[weight($weights)]++; } var_dump($values);

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
