按键合并数组并求和另一个键

Merge array by key and sum another key(按键合并数组并求和另一个键)

问题描述

我有这个数组，我需要按名称"键合并，还需要求和键价格"，更多代码示例.键是静态的.

I have this array and I need merge by key "name", also sum key "price", more in code example. Keys are static.

Array
(
    [0] => Array
        (
            [name] => Sapiente quo incidunt nostrum dolore
            [price] => 50
        )

    [1] => Array
        (
            [name] => Global Donation
            [price] => 10
        )

    [2] => Array
        (
            [name] => Global Donation
            [price] => 10
        )

)

想要的结果:

Array
(
    [0] => Array
        (
            [name] => Sapiente quo incidunt nostrum dolore
            [price] => 50
        )

    [1] => Array
        (
            [name] => Global Donation
            [price] => 20
        )
)

非常感谢

推荐答案

好的，我找到了

    $items = array();
    foreach($prepare as $k=>$v) {
        if(!isset($items[$v['name']])) {
            $items[$v['name']] = $v;
        } else {
            $items[$v['name']]['price'] += $v['price'];
        }
    }
