PHP -需要帮助将数组插入到给定键的关联数组中

Ok, so I have an array like so:

我有一个这样的数组:

$buttons = array(
    'home' => array(
        'title' => $txt['home'],
        'href' => $scripturl,

    'login' => array(

    'register' => array(
        'title' => $txt['register'],
        'href' => $scripturl . '?action=register',

        'sub_buttons' => array(
        ),
        'is_last' => !$context['right_to_left'],
    ),
    'logout' => array(
        'title' => $txt['logout'],
        'href' => $scripturl . '?action=logout;%1$s=%2$s',
        'show' => !$user_info['is_guest'],
        'sub_buttons' => array(
        ),
        'is_last' => !$context['right_to_left'],
    ),
);

Now I want to be able to insert an array into it, either before or after any of the keys within the array above. The array that I want to insert can look like this:

现在我想要能够插入一个数组，在上面数组中的任何一个键之前或之后。我要插入的数组如下:

$new_menu_buttons['testing'] = array(
    'title' => $txt['testing'],
    'href' => $scripturl . '?action=testing',
    'show' => true,
    'target' => '_self',
    'active_button' => false,
);

Someone recommended functions to handle this and methods to use, but I'm not sure how to do this, they are wanting offsets for these functions also. Here is the function structure that someone recommended I use for this, than just call these functions when needed:

有人建议用函数来处理这个和使用的方法，但是我不确定该怎么做，他们也想要这些函数的偏移量。这里是我推荐使用的函数结构，而不是在需要时调用这些函数:

function array_insert_before($array, $key, $new_array)
{
    // Splice array in two at key, keeping key on the right side
    // Append new value on the left tail
    // Glue both arrays into a new array
    // Return new array
}
function array_insert_after($array, $key, $new_array)
{
    // Symmetric with right & left switched
}

So, I want to be able to call the functions like so:

我想把函数命名为

If it needs to go after the key, 'home' that is specified:

如果需要按键，则指定“home”:

$menu_buttons = array_insert_after($buttons, 'home', $new_menu_buttons);

If it needs to go before the key, 'home' that is specified:

如果需要在键前移动，则指定“home”:

$menu_buttons = array_insert_before($buttons, 'home', $new_menu_buttons);

Basically, I really need help with these functions, any help would be great.

基本上，我真的需要这些功能的帮助，任何帮助都是好的。

Should I be using array_splice or array_slice? Would someone be willing to start me off in the right direction here with some actual code please?

我应该使用array_splice还是array_slice?有人愿意让我从正确的方向出发用一些实际的代码吗?

Thanks guys :)

谢谢大家:)

This should get you started. Note: I haven't tested this. It's off the top of my head.

这应该能让你开始。注意:我没有测试过这个。它在我的头顶上。

/**
 * This will insert $new at the beginning if $key is not found
 */
function array_insert_before($array, $key, $new)
{
    $keys = array_keys($array);
    $pos = (int) array_search($key, $keys);
    return array_merge(
        array_slice($array, 0, $pos),
        $new,
        array_slice($array, $pos)
    );
}

array_insert_after() is pretty much the same, except $pos is increased by one. You should be able to figure that out by yourself.

array_insert_after()几乎是一样的，除了$pos增加了1。你应该可以自己算出来。

Ok, after playing with it for quite some time, I finally got it working the way I want it. I am using certain keys within the $new_menu_buttons to decide on what to do. e.g.: position tells me if it is after or before, parent tells me where to search for the key at, and slug gives me the key to use for each new menu array that gets added. array_splice isn't working for me, so I'm using the array_merge approach instead which works just great. Here it is for anyone else who gets stuck with this problem.

好吧，在玩了一段时间之后，我终于让它按我想要的方式运行了。我在$new_menu_buttons中使用某些键来决定要做什么。例如:position告诉我是在后面还是在前面，parent告诉我在哪里查找at键，slug给我添加的每个新菜单数组的键。array_splice对我不起作用，所以我使用了array_merge方法，效果非常好。这是给其他陷入这个问题的人的。

function array_insert_buttons($buttons, $new_menu_buttons)
{
    foreach($new_menu_buttons as $new)
    {
        $keys = array_keys($buttons);
        $position = (int)array_search($new['parent'], $keys);

        if ($new['position'] == 'after')
            $position = $position + 1;

        // Create the new array in the correct format, using the slug!
        $new_button = array();
        $new_button[$new['slug']] = $new;

        // Don't need these keys anymore.
        unset($new_button[$new['slug']]['position']);
        unset($new_button[$new['slug']]['parent']);
        unset($new_button[$new['slug']]['slug']);

        // Putting it all together now.
        $buttons = array_merge(
            array_slice($buttons, 0, $position),
            $new_button,
            array_slice($buttons, $position)
        );
    }

    return $buttons;
}

Thanks for your help guys :)

谢谢你们的帮助
