Php 合并两个数组并添加数组计数的值

我有两个这样的数组

$arr1 = array('Prabhash', 'Nagda', 'Sayyed','Prabhash');
$arr2 = array('4', '1', '2','5');
echo "<pre>";
print_r($arr1);
print_r($arr2);

<?php
$arr1 = array('Prabhash', 'Nagda', 'Sayyed','Prabhash');
$arr2 = array('4', '1', '2','5');
$result=array();
foreach($arr1 as $key => $value)
{
    if(isset($result[$value]))
    {
        $result[$value][1]+=$arr2[$key];
    }
    else
    {
        $result[$value]=array($value,$arr2[$key]);
    }
}
$result=  array_values($result);
print_r($result);

我曾尝试合并和合并阵列，但没有成功，希望有人能帮助我做得更好。

试试看

 Array
(
    [0] => Array
        (
            [0] => Prabhash
            [1] => 9
        )

    [1] => Array
        (
            [0] => Nagda
            [1] => 1
        )

    [2] => Array
        (
            [0] => Sayyed
            [1] => 2
        )

)

使用

数组映射

，

数组键

，

数组翻转

，

数组唯一

，

数组相交键

和

数组求和

功能的简短解决方案：

使用array mergeOMG我刚刚回到这一页来吹嘘我为这个问题做的一行代码，并开玩笑说在我的解决方案中使用了这么多函数！你已经发布了我的准确代码！！！啊！（…向上投票）
