问题描述
$transactions = array (
array( 'SiteID' => 147, 'Amount' => '500.00', 'TransactionType' => 'Deposit' ),
array( 'SiteID' => 147, 'Amount' => '500.00', 'TransactionType' => 'Redemption'),
array( 'SiteID' => 147, 'Amount' => '1500.00', 'TransactionType' => 'Deposit' ),
array( 'SiteID' => 147, 'Amount' => '200.00', 'TransactionType' => 'Reload' ),
array( 'SiteID' => 150, 'Amount' => '100.00', 'TransactionType' => 'Deposit' ),
array( 'SiteID' => 3, 'Amount' => '500.00', 'TransactionType' => 'Redemption' ),
array( 'SiteID' => 150, 'Amount' => '200.00', 'TransactionType' => 'Redemption' ),
array( 'SiteID' => 3, 'Amount' => '500.00', 'TransactionType' => 'Deposit' ),
array( 'SiteID' => 3, 'Amount' => '200.00', 'TransactionType' => 'Deposit' ),
array( 'SiteID' => 3, 'Amount' => '200.00', 'TransactionType' => 'Reload' ),
array( 'SiteID' =>147, 'Amount' => '500.00', 'TransactionType' => 'Redemption' )
);
$totals = null;
foreach ($transactions as $t){
$amount = (float) $t['Amount'];
if (isset($totals[ $t['SiteID'] ][ $t['TransactionType'] ])){
$totals[ $t['SiteID'] ][ $t['TransactionType'] ] += (float) $amount;
} else {
$totals[ $t['SiteID'] ][ $t['TransactionType'] ] = (float) $amount;
}
}
print_r ($totals);
这里的code，但它打印的是这样的：
Here's the code but it print's like this:
Array ( [147] => Array ( [D] => 455500 [W] => 460216.4 [R] => 158000 )
[145] => Array ( [D] => 85500 [W] => 78763.75 [R] => 14500 )
[146] => Array ( [D] => 64200 [W] => 91121.94 [R] => 42800 )
我需要的print_r的结果是这样的：
I need to print_r the result like this:
Array ( [147] => Array ( [Deposit] => 455500 [Redemption] => 460216.4 [Reload] => 158000 )
[145] => Array ( [Deposit] => 85500 [Redemption] => 78763.75 [Reload] => 14500 )
[146] => Array ( [Deposit] => 64200 [Redemption] => 91121.94 [Reload] => 42800 )
的R - 刷新，W - 赎回和D - 存款
感谢，并请响应。
推荐答案
尝试
foreach ($transactions as $k=>$t){
$amount = (float) $t['Amount'];
if (isset($totals[ $t['SiteID'] ][ $t['TransactionType'] ])){
$totals[ $t['SiteID'] ][ $t['TransactionType'] ] += (float) $amount;
} else {
$totals[ $t['SiteID'] ][ $t['TransactionType'] ] = (float) $amount;
}
}
