這篇文章主要為大家詳細介紹了php生成紅包機率算法簡單示例，具有一定的參考價值，可以用來參考一下。
對php生成紅包機率算法簡單示例感興趣的小夥伴，下面一起跟随512筆記的小編巴閉妹來看看吧！
function getRandMoney($totalMoney, $totalPeople=2, $miniMoney=1){
$randRemainMoney = $totalMoney - $totalPeople * $miniMoney;//剩餘需要随機的錢數
return _getRandMoney($randRemainMoney, $totalPeople, $miniMoney);
}
function _getRandMoney($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'] = '參數傳遞有誤，生成紅包失敗';
}
return $returnMessage;
}
function _randMoney($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;
}
