根据个人对微信红包的理解，下午无聊写了一个微信生成红包的方案
设计思路：
1、微信红包，每人最少分得1分钱
2、每人分得到的金额是随机分配的
3、每次生成红包就生成了对应领取红包的结果

/**生成红包的函数*/ function getRandMoney($totalMoney, $totalPeople=2, $miniMoney=1){ $randRemainMoney = $totalMoney - $totalPeople * $miniMoney;//剩余需要随机的钱数 return _getRandMoney($randRemainMoney, $totalPeople, $miniMoney); } /**红包生成的逻辑代码*/ function _getRandMoney($totalMoney, $totalPeople, $miniMoney){ $returnMessage = array('status'=>1, 'data'=>NULL); if($totalMoney > 0){ $returnMessage['data'] = _randMoney($totalMoney, $totalPeople, $miniMoney); }elseif($totalMoney == 0){ $returnMessage['data'] = array_fill(0, $totalPeople, 1); }else{ $returnMessage['status'] = -1; $returnMessage['data'] = '参数传递有误，生成红包失败'; } return $returnMessage; } /*参数无误，开始生成对应的红包金额*/ function _randMoney($totalMoney, $totalPeople, $miniMoney){ $data = array_fill(0, $totalPeople, $miniMoney); if($totalPeople > 1){ foreach($data as $k => $v){ if($k == $totalPeople -1){ $data[$k] = $totalMoney + $v; break; }else { if($totalMoney == 0) break; $randMoney = rand(0, $totalMoney); $totalMoney -= $randMoney; $data[$k] = $randMoney + $v; } } } return $data; } |
