多重if判断如何简化代码，减少代码冗余

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。】。

public function bonusUser($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) {

一个最直接有效的方法，以你的代码为例：

if($user['agentid']!=0)
{//一级上线
    ... //一级上线逻辑
}
return false;

你可以转换成

if($user['agentid']==0)
{
    return false;
}
... //一级上线逻辑

这样 一级上线 的逻辑不就少了一层嵌套了？里面的嵌套同理可以优化

最后，要告诉你的是不要乱打标签，你这是 javascript 问题吗？

代理关系和业务相关，没看明白你代码

$level = $user_one['level'];
$levelArray = [11=>168, 12=>138];

if(isset($levelArray[$level])){
    $subNum = $levelArray[$level];
} else {
    $subNum = 268;
}

$result_num=$money_one-$subNum;
if($result_num>0){
    $return_price=$result_num*$order_goods['total'];
}

合理使用switch和三元运算符 还有短路运算

多个if else 的时候使用switch 判断的时候使用三元运算符 PHP7就更简单了!
