如何将两个值合并/组合为同一数组中的单个键 - How to merge/combine two values into single key in the same array

How to merge/combine two values into single key in the same array

我不确定什么是适合我的标题的术语，但只是想知道下面的解决方案需要将两个值合并/组合成一个关联数组。例如，我有一个数组：

Array
(
 [1] => Array
    (
        [agent_name_1] => Agent 1
        [agent_phone_1] => 0123456
        [agent_company_1] => My Company
        [agent_email_1] => agent@yahoo.com
        [agent_address_1] => United States
    )
 )

在这里，我想把company_1和address_1结合起来。所以输出应该是这样的：

Array
(
 [1] => Array
    (
        [agent_name_1] => Agent 1
        [agent_phone_1] => 0123456
        [agent_email_1] => agent@yahoo.com
        [agent_address_1] => My Company, United States
    )
 )

请有人帮我找出解决这个问题的最简单的方法。

您需要循环遍历数组并修改原始数组的相应键。

foreach ($array as $key => $agent) {
  $array[$key]['agent_address_1'] = $agent['agent_company_1'] . ', ' . $agent['agent_address_1'];
  unset($array[$key]['agent_company_1']);
}

您可以在代码中使用array_map()，如下所示：

<?php
$MyArray[1] = array (
        'agent_name_1' => 'Agent 1',
        'agent_phone_1' => '0123456',
        'agent_company_1' => 'My Company', 
        'agent_email_1' => 'agent@yahoo.com', 
        'agent_address_1' => 'United States'
    );
$array = array_map(function($n) {$n['agent_address_1'] = $n['agent_company_1'] . ', ' . $n['agent_address_1']; unset($n['agent_company_1']); return $n;}, $MyArray);
print_r($array);

输出：

Array
(
    [1] => Array
        (
            [agent_name_1] => Agent 1
            [agent_phone_1] => 0123456
            [agent_email_1] => agent@yahoo.com
            [agent_address_1] => My Company, United States
        )
)
