PHP数组总和集团通过[复制](Php Arrays Sum Group By [duplicate

使用多维阵列由SUM PHP组

我工作的一个批发公司创建购物推车。我将创建以后也发票。这是同样的道理。

首先，我乘的一揽子贷款（包）*一揽子贷款adeti（包装数量）*fiyatı（价格），我写了它在列表的末尾。现在我要计算增值税。主要的问题是，我们并不确切地知道以前的增值税率。

可以存在3分不同的大桶比率。（这取决于其客户选择的产品）可能是一个。

我制成大桶的阵列

$vats[] = array($row['vat'], $row['wholesaleprice'] - $wholesaleprice);

结果就是这样

Array ( 
[0] => Array ( [0] => 18 [1] => 1,07 ) 
[1] => Array ( [0] =>  8 [1] => 0,44 ) 
[2] => Array ( [0] =>  8 [1] => 0,67 ) 
[3] => Array ( [0] => 18 [1] => 0,55 ) 
[4] => Array ( [0] => 18 [1] => 0,19 ) 
[5] => Array ( [0] =>  8 [1] => 0,48 ) 
[6] => Array ( [0] => 18 [1] => 2,59 ) 
[7] => Array ( [0] =>  8 [1] => 0,15 ) 
[8] => Array ( [0] => 18 [1] => 12,97 ) 
)

我有比要总结增值税组...

我要像显示

VAT（18％）136.26 TL VAT（8％）16.90 TL VAT（1％）9.28 TL

我如何能做到这一点的快捷方式。我已经检查阵列功能。但我无法找到任何有用的。

Answer 1:

尝试是这样的：

<?php

$data = Array ( 
    Array ( 0 => '18', 1 => '1,07' ),
    Array ( 0 => '8', 1 => '0,44' ),
    Array ( 0 => '8', 1 => '0,67' ),
    Array ( 0 => '18', 1 => '0,55' ), 
    Array ( 0 => '18', 1 => '0,19' ),
    Array ( 0 => '8', 1 => '0,48' ),
    Array ( 0 => '18', 1 => '2,59' ),
    Array ( 0 => '8', 1 => '0,15' ),
    Array ( 0 => '18', 1 => '12,97' ) 
);

// predefine array
$data_summ = array();
foreach ( $data as $value ) {
    $data_summ[ $value[0] ] = 0;
}

foreach ( $data as $list ) {
    $number = str_replace( ",", ".", $list[1] ) * 1;
    $data_summ[ $list[0] ] += (float)$number;
}

?>

输出$data_summ ：

Array
(
    [8] => 1.74
    [18] => 17.37
)

如果我理解正确。

Answer 2:

<?php

function multiplyArray($array) {
    $result = array();

    foreach ($array as $value) {
        $result[] = array_product(array_map('floatval', str_replace(',', '.', $value)));
    }

    return $result;
}

$array = array(
    0 => array(0 => '18', 1 => '1,07'),
    1 => array(0 => '8', 1 => '0,44'),
    2 => array(0 => '8', 1 => '0,67'),
    3 => array(0 => '18', 1 => '0,55'),
    4 => array(0 => '18', 1 => '0,19'),
    5 => array(0 => '8', 1 => '0,48'),
    6 => array(0 => '18', 1 => '2,59'),
    7 => array(0 => '8', 1 => '0,15'),
    7 => array(0 => '18', 1 => '12,97'),
);

// Outputs
var_dump($array);
var_dump(multiplyArray($array));
var_dump(array_sum(multiplyArray($array)));
