如何總結數組值？

要清楚，這裏的輸入數據：如何總結數組值？

陣列（ [0] =>數組（ [SITEID] => 147 [量] => 500.00 [TRANSACTIONTYPE] => d ）

[1] => Array 
    (
     [SiteID] => 145 
     [Amount] => 500.00 
     [TransactionType] => D 
    ) 

[2] => Array 
    (
     [SiteID] => 145 
     [Amount] => 500.00 
     [TransactionType] => D 
    ) 

[3] => Array 
    (
     [SiteID] => 147 
     [Amount] => 500.00 
     [TransactionType] => D 
    ) 

[4] => Array 
    (
     [SiteID] => 146 
     [Amount] => 500.00 
     [TransactionType] => D 
    ) 
[5] => Array 
    (
     [SiteID] => 146 
     [Amount] => 500.00 
     [TransactionType] => D 
    ) 
[6] => Array 
    (
     [SiteID] => 145 
     [Amount] => 500.00 
     [TransactionType] => W 
    ) 

[7] => Array 
    (
     [SiteID] => 145 
     [Amount] => 500.00 
     [TransactionType] => W 
    ) 

[8] => Array 
    (
     [SiteID] => 146 
     [Amount] => 330.00 
     [TransactionType] => W 
    ) 

[9] => Array 
    (
     [SiteID] => 146 
     [Amount] => 500.00 
     [TransactionType] => W 
    ) 

[10] => Array 
    (
     [SiteID] => 3 
     [Amount] => 500.00 
     [TransactionType] => D 
    )

我需要讓所有的交易一樣SITEID的總和，它是TRANSACTIONTYPE例如像：

d - 礦牀，W - 重新demption，R - 刷新

結果：array ([147]=>array([Deposit] => 1000, [Reload]=>3000, [Redemption]=>2000))

注意：147是一個SITEID。

我需要計算存款，重新加載，兌換同一SiteID的所有交易。

如果SiteID存在多次，只需在每個週期添加存款，重新加載和贖回。 :)

請回應。謝謝，並以適當的方式引導我！

所以，你想從大陣裏面總結了所有的值？ – 2012-08-09 08:54:23

什麼是輸入？ – lvil 2012-08-09 08:54:50

['$ sum = array_sum（$ result ['SiteId']）;']（http://uk.php.net/manual/en/function.array-sum.php）？ – DaveRandom 2012-08-09 08:54:50

試試這個

<?php 
$array=array ("SiteID"=>array("Deposit" => 1000, "Reload"=>3000, "Redemption"=>2000)); 
$val=0; 
foreach($array["SiteID"] as $key=>$value){ 
$val=$val+$value; 
} 
echo $val; 
?>

$values = array(
    'Deposit' => 0, 
    'Reload'  => 0, 
    'Redemption' => 0 
); 
foreach ($array as $item) { 
    $values[$item['SiteID']] += array_sum($item['SiteID']); 
} 
print_r($values);
