我如何才能简化一个嵌套的PHP数组？ [英] How can I simplify a nested php array?

问题描述

我在写一个PHP Web应用程序在那里我有一个嵌套的数组，类似于以下内容：

I'm writing a php web application where I have a nested array which looks similar to the following:

$results = array(
        array(
            array(
                'ID' => 1,
                'Name' => 'Hi'
            )
        ),
        array(
            array(
                'ID' => 2,
                'Name' => 'Hello'
            )
        ),
        array(
            array(
                'ID' => 3,
                'Name' => 'Hey'
            )
        )
    );

目前，这意味着，当我要使用的ID字段我要叫 $结果[0] [0] ['身份证'] 这是相当低效和拥有超过几百个记录的数组变得混乱很快。我想数组缩减下来，让我可以叫 $结果[0] ['身份证'] 代替。

Currently this means that when I want to use the ID field I have to call $results[0][0]['ID'] which is rather inefficient and with an array of over several hundred records becomes messy quickly. I would like to shrink the array down so that I can call $results[0]['ID'] instead.

我的理解是，使用一个foreach循环遍历数组中的每一行进行迭代并更改格式的职能将是去改变 $结果的格式数组，但我努力理解要做什么foreach循环都有每个初始阵列后。

My understanding is that a function that uses a foreach loop to iterate through each row in the array and change the format would be the best way to go about changing the format of the $results array but I am struggling to understand what to do after the foreach loop has each initial array.

下面是code我到目前为止有：

Here is the code I have so far:

public function filterArray($results) {
    $outputArray = array();

    foreach ($results as $key => $row) {

    }

    return $outputArray;
}

会有人能够提出最有效的方式来实现我追求的？

Would anyone be able to suggest the most effective way to achieve what I am after?

感谢：）

推荐答案

只需使用的 call_user_func_array 为

Simply use call_user_func_array as

$array = call_user_func_array('array_merge', $results);
print_r($array);
