PHP数组心集团通过 [英] Php Arrays Sum Group By

问题描述

可能重复：结果
  通过SUM PHP组使用多维数组

我工作的一个批发公司创建的购物推车。我将创建后来也发票。这是同样的道理。

I'm working on creating shopping-cart for a wholesale company. And i'll create also invoice later. It's same logic.

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。

Firstly, i multiply paket (package) * paket adeti (package quantity) * fiyatı (price) And i wrote it at the end of list. Now i have to calculate vat. The main problem is we don't know vat ratios exactly before.

可能存在3种不同的增值税率。 （这取决于哪个客户选择产品）可以是一个。

May be there exist 3 different vat ratios. (it depends on the products which customer selects) May be one.

我做了大桶的数组

$vats[] = array($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 ) 
)

我要总结通过比增值税组...

I have to sum vat group by ratios...

我要像显示

增值税（18％），136,26 TL
增值税（8％）16,90 TL
增值税（1％）9,28¥

VAT (%18) 136,26 TL VAT (%8) 16,90 TL VAT (%1) 9,28 TL

我该怎么办，在快捷方式。我已经检查数组功能。但我无法找到任何有用的东西。

How can i do that in shortcut. I've check array functions. But i couldn't find anything useful.

推荐答案

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。
