陣列的印刷

Question

可能重複：
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); 

} 

的關鍵應該是SITEID，我該怎麼辦呢？

我需要這種輸出：

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")) 

的關鍵應該是SITEID。請修改了代碼:(

Answer 1

這是正常的，因爲你正在使用array_merge（），看看在文檔：http://php.net/manual/en/function.array-merge.php

值用數字鍵輸入數組中將會 遞增鍵重新編號從零結果數組中

所以你SITEID這是關鍵將重新編號。

開始，然後讓你的鑰匙，它會更好要做到這一點：

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