根据codeigniter

Question

我从数据库中得到2个数组，在这两个数组中都有一个capital_payment，两者都是80。所以我想要完成的是，用户给出了我从$ amount获得的输入，90，然后我只选择小于90的行，如果用户选择160或160+我返回两行，如果用户选择159我只返回一行。所以这基本上是我需要处理的标准。我试图根据标准返回数组中的数据。但是我犯了许多错误，所以需要帮助。

public function GetSellLoanData($token, $amount, $expirationDate, $radioChecked, $orig_id)
{
    $result =  $this->investment->getLoansBorrowedData($id, $orig_id);
    $foo = json_decode(json_encode($result), true);
    $amountTemp = 0;
    $data = array();
    foreach($foo as $investment)
    {
        //check if input Amount greater than $AmountTemp from for each loop
        if($amount > $amountTemp)
        {
            $data[] = $investment;      

            //DO a check to see what happens to the array data
            foreach($data[] as $check){

            }
            // see if the new array did not exceed the $amount 

            //adding rows here
            $data[] = $investment;

            }else{
                break;
            }
            $amountTemp += $investment['capital_payment'];
        }
      return $data;
    }
}    

而且我还要返回所选数组中的所有其他信息，所以我猜我的$ data数组也不对。

做了一些新的改变！希望这有效！

 $amountTemp = 0;
 $data = array();
 foreach($foo as $investment)
 {
     //check if input Amount greater than $AmountTemp from for each loop
     if($amount > $amountTemp + $investment['capital_payment'])
     {
          $data[] = $investment;      
     }else{
                break;
          }
      $amountTemp += $investment['capital_payment'];
  }
