廢話不多說了，一切解釋盡在代碼中，具體代碼如下所示：
/*** @param $total [你要發的紅包總額]* @param int $num [發幾個]* @return array[生成紅包金額]*/function getRedGift($total, $num = 10){$min = 0.01;$wamp = array();$returnData = array();for ($i = 1; $i < $num; ++$i) {$safe_total = ($total - ($num - $i) * $min) / ($num - $i); //紅包金額的最大值if ($safe_total < 0) break;$money = @mt_rand($min * 100, $safe_total * 100) / 100;//隨機產生一個紅包金額$total = $total - $money;//剩余紅包總額$wamp[$i] = round($money, 2);//保留兩位有效數字}$wamp[$i] = round($total, 2);$returnData['MoneySum'] = $wamp;$returnData['newTotal'] = array_sum($wamp);return $returnData;}//測試$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)*/ 代碼到此就給大家寫完了，希望對大家有所幫助！更多有關php 生成紅包的程序代碼盡在VeVb武林網網站，請登陸我們的官網了解更多資訊，謝謝！
