如下列代码。充斥着各种if语句。完全不知道从哪里开始优化..不知道有什么办法可以解决这种多重if判断..减少代码冗余提升效率。下列代码的功能就是一个查找7级上线代理的功能【查询该用户的上线是否存在上线代理-需要往上查询7级，如果存在，给予一定的返现，前三级需要通过序列化保存在一个字段，后五级只需要返现。】。publicfunctionbonusUser($user,$orderinfo,$order_goods){$first_price=$this->getPrice($user['level']);if($user['agentid']!=0){//一级上线//下线成交价$user_one=\think\Db::table('ims_ewei_shop_member')->where('id',$user['agentid'])->find();$money_one=$orderinfo['price']/$order_goods['total'];//获取当前代理价后并计算所得佣金$new_price=$this->getPrice($user_one['level']);$return_price=0;//反序列化佣金$all_moeny=unserialize($order_goods['commissions']);if($user_one['level']==11){$result_num=$money_one-168;if($result_num>0){$return_price=$result_num*$order_goods['total'];}}elseif($user_one['level']==12){$result_num=$money_one-138;if($result_num>0){$return_price=$result_num*$order_goods['total'];}}elseif($user_one['level']==13){$result_num=$money_one-118;if($result_num>0){$return_price=$result_num*$order_goods['total'];}}else{$result_num=$money_one-268;if($result_num>0){$return_price=$result_num*$order_goods['total'];}}if($return_price>0){$send_one=$this->send_Mess($user_one['openid'],$user['nickname'],1);$all_moeny['level1']=$return_price;}else{$all_moeny['level1']=0;}if($user_one['agentid']!=0){//二级上线$user_two=\think\Db::table('ims_ewei_shop_member')->where('id',$user_one['agentid'])->find();$new_price_two=$this->getPrice($user_two['level']);//这里判断如果上级的会员等级比下级低的情况不考虑佣金返还if($user_two['level']>$user_one['level']&&$user_one['level']>=$user['level']){$result_two=$new_price-$new_price_two;\think\Log::write($new_price,"1j");if($result_two>0){$all_moeny['level2']=$result_two*$order_goods['total'];$send_two=$this->send_Mess($user_two['openid'],$user['nickname'],2);}else{$all_moeny['level2']=0;}}elseif($user_one['level']<=$user['level']&&$user_two['level']>$user['level']){//如果该级上层比任何级别代理都高的情况下$result_two=$first_price-$new_price_two;$all_moeny['level2']=$result_two*$order_goods['total'];if($result_two>0){$send_three=$this->send_Mess($user_two['openid'],$user['nickname'],2);}}else{$all_moeny['level2']=0;}if($user_two['agentid']!=0){//三级上线$user_three=\think\Db::table('ims_ewei_shop_member')->where('id',$user_two['agentid'])->find();$new_price_three=$this->getPrice($user_three['level']);//这里判断如果上级的会员等级比下级低的情况不考虑佣金返还if($user_three['level']>$user_two['level']&&$user_two['level']>=$user_one['level']&&$user_one['level']>=$user['level']){$result_three=$new_price_two-$new_price_three;if($result_three>0){$all_moeny['level3']=$result_three*$order_goods['total'];$send_three=$this->send_Mess($user_three['openid'],$user['nickname'],3);}else{$all_moeny['level3']=0;}}elseif($user_two['level']<=$user['level']&&$user_one['level']<=$user['level']&&$user_three['level']>$user['level']){//如果该级上层比任何级别代理都高的情况下$result_three=$first_price-$new_price_three;if($result_three>0){$all_moeny['level3']=$result_three*$order_goods['total'];$send_three=$this->send_Mess($user_three['openid'],$user['nickname'],3);}else{$all_moeny['level3']=0;}}elseif($user_one['level']>=$user['level']&&$user_two['level']<=$user_one['level']&&$user_three['level']>$user_two['level']){$result_three=$new_price-$new_price_three;if($result_three>0){$all_moeny['level3']=$result_three*$order_goods['total'];$send_three=$this->send_Mess($user_three['openid'],$user['nickname'],3);}else{$all_moeny['level3']=0;}}else{$all_moeny['level3']=0;}if($user_three['agentid']!=0){//四级上线$user_four=\think\Db::table('ims_ewei_shop_member')->where('id',$user_three['agentid'])->find();$new_price_four=$this->getPrice($user_four['level']);//这里判断如果上级的会员等级比下级高的情况下。佣金返还；if($user_four['level']>$user_three['level']&&$user_three['level']>=$user_two['level']&&$user_two['level']>=$user_one['level']&&$user_one['level']>=$user['level']){$result_four=$new_price_three-$new_price_four;if($result_four>0){$four_money=$result_four*$order_goods['total'];$result=$this->shop_money_log($four_money,$user_four,4);$send_four=$this->send_Mess($user_four['openid'],$user['nickname'],4);}}elseif($user_three['level']<=$user['level']&&$user_two['level']<=$user['level']&&$user_one['level']<=$user['level']&&$user_four['level']>$user['level']){//如果该级上层比任何级别代理都高的情况下$result_four=$first_price-$new_price_four;$four_money=$result_four*$order_goods['total'];if($result_four>0){$result=$this->shop_money_log($four_money,$user_four,4);$send_four=$this->send_Mess($user_four['openid'],$user['nickname'],4);}}elseif($user_two['level']>=$user['level']&&$user_two['level']>=$user_one['level']&&$user_three['level']<=$user_two['level']&&$user_four['level']>$user_two['level']){$result_four=$new_price_two-$new_price_four;$four_money=$result_four*$order_goods['total'];if($result_four>0){$result=$this->shop_money_log($four_money,$user_four,4);$send_four=$this->send_Mess($user_four['openid'],$user['nickname'],4);}}elseif($user_one['level']>=$user['level']&&$user_three['level']<=$user_one['level']&&$user_one['level']>=$user_two['level']&&$user_four['level']>$user_one['level']){$result_four=$new_price-$new_price_four;$four_money=$result_four*$o
