多维数组array_sum [英] multidimensional array array_sum

问题描述

我所看到的各种发布了关于这个问题，所以我知道一些答案，这可能存在。然而，我没有看完这些明智。

我有一个数组，它是像下面这样。

  [0] =＆GT;排列
    （
        [ID] =＆GT; 95659865986
        [invoiceNumber] =＆GT; 6374324
        [invoiceTitle] =＆GT;每月一次
        [invoiceStatus] =＆GT;付费
        [帐户ID] =＆GT; 6235218753
        [totalExVat] =＆GT; 158.95
        [dateCreated会] =＆GT; 2012年4月1日
        [vatAmount] =＆GT; 20.00
    ）
 

我所希望做的是做这个数组的 vatAmount 值数组总和。

由于以下似乎并不被太多做的。

 （array_sum（$ account_invoices ['vatAmount']）
 

解决方案

只是一个办法做到这一点：

  $总和= 0;的foreach（$ account_invoices为$ NUM =＆GT; $值）{
    $总和+ = $值['vatAmount'];
}
 

I have seen various posted about this question so am aware some answers to this may exist. however I am none the wiser after reading these.

I have an array that is like the following.

[0] => Array
    (
        [id] => 95659865986
        [invoiceNumber] => 6374324
        [invoiceTitle] => Monthly
        [invoiceStatus] => Paid
        [accountId] => 6235218753
        [totalExVat] => 158.95
        [dateCreated] => 1 Apr 2012
        [vatAmount] => 20.00
    )

All I wish to do is do array sum on the vatAmount values of this array.

As the following doesnt seem to be doing much.

(array_sum($account_invoices['vatAmount'])

解决方案

Just a way to do it:

$sum = 0;

foreach($account_invoices as $num => $values) {
    $sum += $values[ 'vatAmount' ];
}
