好的，所以我有一个像这样的数组：

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

        ),
        'is_last' => $context['right_to_left'],
    ),
    'help' => array(
        'title' => $txt['help'],
        'href' => $scripturl . '?action=help',

            'mlist_search' => array(
                'title' => $txt['mlist_search'],
                'href' => $scripturl . '?action=mlist;sa=search',
                'show' => true,
                'is_last' => true,
            ),
        ),
    ),
    'login' => array(
        'title' => $txt['login'],
        'href' => $scripturl . '?action=login',
        'show' => $user_info['is_guest'],
        'sub_buttons' => array(
        ),
    ),
    'register' => array(
        'title' => $txt['register'],
        'href' => $scripturl . '?action=register',
        'show' => $user_info['is_guest'],
        'sub_buttons' => array(
        ),
        'is_last' => !$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'],
    ),
);

现在我希望能够在上面数组中的任何键之前或之后插入一个数组。我要插入的数组可能如下所示：

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

有人推荐了处理这个问题的函数和使用方法，但我不知道该怎么做，他们也想要这些函数的偏移量。这是有人推荐我为此使用的函数结构，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
}

所以，我希望能够像这样调用函数：

如果它需要跟随指定的键，'home'：

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

如果它需要在键之前，指定的 'home' ：

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

基本上，我真的需要这些功能的帮助，任何帮助都会很棒。

我应该使用array_splice还是array_slice？有人愿意在这里用一些实际的代码让我朝着正确的方向开始吗？

多谢你们 ：）

这应该让你开始。注意：我没有测试过这个。它不在我的脑海中。

/**
 * 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()几乎相同，只是$pos增加了 1。你应该能够自己弄清楚。

好的，在玩了一段时间之后，我终于让它按照我想要的方式工作了。我正在使用 $new_menu_buttons 中的某些键来决定要做什么。例如： position 告诉我它是在之后还是之前，parent 告诉我在哪里搜索键，slug 给我用于添加的每个新菜单数组的键。 array_splice对我不起作用，所以我使用的是array_merge效果很好的方法。这是为其他遇到此问题的人准备的。

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;
}

谢谢你们的帮助：）
