php实现的递归提成方案实例

CREATE TABLE `crm_proxy_bonux_rule` (

`id` int(11) NOT NULL AUTO_INCREMENT COMMENT '超过的部份提成规则ID',

`bouns_rule_name` varchar(20) NOT NULL COMMENT '规则名称,如D套餐0-20范围',

`rid` bigint(20) DEFAULT NULL COMMENT '为0,就是默认的全局设置',

`start_rang` smallint(6) DEFAULT NULL COMMENT '开始范围',

`end_rang` smallint(6) DEFAULT NULL COMMENT '结束范围',

`bonus_rate` smallint(6) DEFAULT NULL COMMENT '提成率',

`bonus_reward` decimal(8,2) DEFAULT NULL COMMENT '奖励现金',

`chain_pre` int(11) DEFAULT NULL COMMENT '链表上一个值默认为0,表示根结点',

`chain_next` int(11) DEFAULT NULL COMMENT '链表下一个值',

`is_standard` enum('0','1') DEFAULT '0' COMMENT '是否是标准',

PRIMARY KEY (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf8;

PHP实现代码如下：

private function bouns_recursion($range,$standard,&$rule_list,$amount){

$price = 1000;

$max = $standard['end_rang'] ;//最大值

$min = $standard['start_rang'] ;//最小值

$bonus_rate = $standard['bonus_rate'];//分红率

if($range<$min){

return false;

}

$standard_amount = 0;

$plus = 0;

//是否是标准第一个

if($standard['is_standard']==1){

$standard_amount = $price * $min * $bonus_rate / 100; //求提成 600 300

}else{

$plus = 1; //第二次要累加

}

if($range > $max){

$number = ($max - $min) + $plus;//算出差值值 5 4-3 == 1

$amount = ($price * $number * $bonus_rate / 100); //求提成 200

}else{

$number = ($range - $min ) + $plus;//算出差值值 4 1

$amount = ($price * $number * $bonus_rate / 100); //求提成

}

$amount = $amount + $standard_amount;//800

if(!empty($rule_list[$standard['chain_next']]) && $range > $max){

return $amount += $this->bouns_recursion($range, $rule_list[$standard['chain_next']], $rule_list,$amount);

}

return $amount;

}
