Question

可能重复：
Printing of Array

public function computeGHComponents()
{
    error_reporting (E_ALL^ E_NOTICE);          

    $total = null;

    $result=array();


    foreach ($this->transaction as $t){
        $amount = (float) $t['Amount'];

        if (isset($this->totals[ $t['SiteID'] ][ $t['TransactionType'] ])){
           $this->totals[ $t['SiteID'] ][ $t['TransactionType'] ] += (float) $amount;
        } else {
           $this->totals[ $t['SiteID'] ][ $t['TransactionType'] ] = (float) $amount;
        }
    }

    foreach($this->totals as $key => $value)
    {
        $result =            array_merge($result,array($key=>array("Deposit"=>$value['D'],"Redemption"=>$value['W'],"Reload"=>$value['R']))); 
    }

    print_r($result);   

}

密钥应该是SiteID，我该怎么做？

我需要这种输出：

array ([147]=>array([Deposit] => "total amount", [Reload]=> "total amount" [Redemption]=> "total amount"))

array ([150]=>array([Deposit] => "total amount", [Reload]=> "total amount" [Redemption]=> "total amount"))

array ([3]=> array([Deposit] => "total amount", [Reload]=> "total amount" [Redemption]=> "total amount"))

密钥应该是SiteID。请修改代码：（

Answer 1

这是正常的，因为您正在使用array_merge（），请查看文档：{{3}}

带有数字键的输入数组中的值将重新编号在结果数组中从零开始递增键。

因此，作为密钥的SiteID将重新编号。

然后，为了保留你的钥匙，最好这样做：

$result[$key] = array("Deposit"=>$value['D'], "Redemption"=>$value['W'], "Reload"=>$value['R']);

打印阵列
