Multiple if judges how to simplify code and reduce code redundancy

such as the following code. Filled with all kinds of if statements. I have no idea where to start the optimization.. I don"t know if there is any way to solve this kind of multiple if judgment. Reduce code redundancy and improve efficiency. The function of the following code is to find an online agent at level 7 [query whether there is an online agent for this user-you need to query level 7 up, and if so, give a certain amount of cash back. The first three levels need to be stored in a field through serialization, and the last five levels only need to be returned. ] . 

public function bonusUser($user, $orderinfo, $order_goods) {
        $first_price = $this->getPrice($user["level"]);

Thinkphp php

one of the most direct and effective methods, take your code as an example: 

if($user['agentid']!=0)
{//
    ... //
}
return false;

you can convert it to 

if($user['agentid']==0)
{
    return false;
}
... //

so the logic of first-level online is missing a layer of nesting? In the same way, the nesting inside can be optimized

< hr >

finally, what I want to tell you is not to indiscriminately tag . Is this a javascript problem?

Agent relationship is related to business. I don't understand your code 

$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'];
}

rational use of switch and ternary operators and short-circuit operation

it is easier to use the ternary operator PHP7 when using switch to judge multiple if else.
