Example of recursive commission scheme implemented in php_php skills

The example in this article describes the recursive commission scheme implemented in PHP. Share it with everyone for your reference, the details are as follows:

The recursive commission scheme has been used in recent CRM projects. The analysis is as follows:

The SQL statement is as follows:

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;

The PHP implementation code is as follows:

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;
}
