废话不多说了,一切解释尽在代码中,具体代码如下所示:
/*** @param $total [你要发的红包总额]* @param int $num [发几个]* @return array[生成红包金额]*/function getRedGift($total, $num = 10){$min = 0.01;$wamp = array();$returnData = array();for ($i = 1; $i < $num; ++$i) {$safe_total = ($total - ($num - $i) * $min) / ($num - $i); //红包金额的最大值if ($safe_total < 0) break;$money = @mt_rand($min * 100, $safe_total * 100) / 100;//随机产生一个红包金额$total = $total - $money;//剩余红包总额$wamp[$i] = round($money, 2);//保留两位有效数字}$wamp[$i] = round($total, 2);$returnData['MoneySum'] = $wamp;$returnData['newTotal'] = array_sum($wamp);return $returnData;}//测试$data = getRedGift(100, 10);print_r($data);//result:/*Array([1] => 8.7[2] => 10.09[3] => 6.23[4] => 6.87[5] => 0.47[6] => 3.12[7] => 7.52[8] => 12.21[9] => 20.53[10] => 24.26)*/
