問題描述

我正在編寫一個 php Web 應用程序，其中有一個類似于以下內容的嵌套數組:

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'
            )
        )
    );

目前這意味著當我想使用 ID 字段時，我必須調用 $results[0][0]['ID'] 這相當低效，并且有多個數組一百條記錄很快變得混亂.我想縮小數組，以便我可以調用 $results[0]['ID'] 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 foreach 循環遍歷數組中的每一行并更改格式的函數將是更改 $results 數組格式的最佳方法，但是我很難理解在 foreach 循環擁有每個初始數組后要做什么.

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.

這是我目前的代碼:

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

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

    }

    return $outputArray;
}

誰能提出最有效的方法來實現我所追求的目標?

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

謝謝:)

推薦答案

只需使用 call_user_func_array as

Simply use call_user_func_array as

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