合并2多维数组和价值总和 [英] Merge 2 multi-dimension arrays and sum value

问题描述

我有一个存储X和Y坐标我想一起合并成一个单一的阵列，而preserving x的值，但增加的y值在一起的两个多维数组。

阵列1：

 阵列（
[0] =＆GT;排列
    （
        [X] =＆GT; 1327449600000
        [Y] =＆GT;五
    ）[1] =＆GT;排列
    （
        [X] =＆GT; 1327450500000
        [Y] =＆GT; 1
    ）
 

阵列2：

 阵列（
[0] =＆GT;排列
    （
        [X] =＆GT; 1327449600000
        [Y] =＆GT; 1
    ）[1] =＆GT;排列
    （
        [X] =＆GT; 1327450500000
        [Y] =＆GT; 3
    ）
 

所以合并的结果将是：

 阵列（
[0] =＆GT;排列
    （
        [X] =＆GT; 1327449600000
        [Y] =＆GT; 6
    ）[1] =＆GT;排列
    （
        [X] =＆GT; 1327450500000
        [Y] =＆GT; 4
    ）
 

任何帮助将大大AP preciated。

解决方案

 函数add_array（$ A1，A2 $）{
    $ C =计数（$ A1）;
    为（$ I = 0; $ I＆LT; $ C，$ I ++）{
        如果（使用isset（$ A2 [$ i]）及和放大器;使用isset（$ A2 [$ i] ['Y']））{
            $ A1 [$ i] ['Y'] + = $ A2 [$ i] ['Y'];
        }
    }
    返回$ A1;
}
 

I have two multidimensional arrays which store x and y coordinates I am trying to merge together into a single array while preserving the x value but adding together the y values.

Array 1:

Array(
[0] => Array
    (
        [x] => 1327449600000
        [y] => 5
    )

[1] => Array
    (
        [x] => 1327450500000
        [y] => 1
    )

Array 2:

 Array(
[0] => Array
    (
        [x] => 1327449600000
        [y] => 1
    )

[1] => Array
    (
        [x] => 1327450500000
        [y] => 3
    )

So the combined outcome would be:

 Array(
[0] => Array
    (
        [x] => 1327449600000
        [y] => 6
    )

[1] => Array
    (
        [x] => 1327450500000
        [y] => 4
    )

Any help would be greatly appreciated.

解决方案

function add_array($a1, $a2) {
    $c = count($a1);
    for ($i=0;$i<$c;$i++) {
        if (isset($a2[$i]) && isset($a2[$i]['y'])) {
            $a1[$i]['y'] += $a2[$i]['y'];
        }
    }
    return $a1;
}
