array_push() 带键值对 [英] array_push() with key value pair

问题描述

我有一个要添加值的现有数组.

I have an existing array to which I want to add a value.

我正在尝试使用 array_push() 来实现这一目标，但无济于事.

I'm trying to achieve that using array_push() to no avail.

下面是我的代码:

$data = array(
    "dog" => "cat"
);

array_push($data['cat'], 'wagon');

我想要实现的是将 cat 作为键添加到 $data 数组中，以 wagon 为值，以便访问它如以下代码段所示:

What I want to achieve is to add cat as a key to the $data array with wagon as value so as to access it as in the snippet below:

echo $data['cat']; // the expected output is: wagon

我怎样才能做到这一点?

How can I achieve that?

推荐答案

那么拥有:

$data['cat']='wagon';
