好的，所以我有一个这样的数组：
$buttons = array(
'home' => array(
'title' => $txt['home'],
'href' => $scripturl,
'show' => true,
'sub_buttons' => array(
),
'is_last' => $context['right_to_left'],

'href' => $scripturl . '?action=profile;area=forumprofile',
'show' => allowedTo(array('profile_extra_any', 'profile_extra_own')),

),
'pm' => array(

'href' => $scripturl . '?action=pm',
'show' => $context['allow_pm'],
'sub_buttons' => array(

'title' => $txt['pm_menu_send'],
'href' => $scripturl . '?action=pm;sa=send',
'show' => allowedTo('pm_send'),
'is_last' => true,
),
),
),
'calendar' => array(
'title' => $txt['calendar'],
'href' => $scripturl . '?action=calendar',
'show' => $context['allow_calendar'],
'sub_buttons' => array(
'view' => array(
'title' => $txt['calendar_menu'],
'href' => $scripturl . '?action=calendar',
'show' => allowedTo('calendar_post'),

),
'mlist' => array(

'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向其中插入一个数组。我想插入的数组可以是这样的：
$new_menu_buttons['testing'] = array(
'title' => $txt['testing'],
'href' => $scripturl . '?action=testing',
'show' => true,
'target' => '_self',
'active_button' => false,
);
有人推荐了处理这个问题的函数和使用的方法，但我不确定如何做到这一点，他们也希望这些函数的偏移量。以下是有人建议我使用的函数结构，而不仅仅是在需要时调用这些函数：
function array_insert_before($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，我希望能够调用这样的函数：
如果它需要在密钥之后，指定的"home"：
$menu_buttons = array_insert_after($buttons, 'home', $new_menu_buttons);
如果它需要在键之前，指定的"主页"：
$menu_buttons = array_insert_before($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？有人愿意用一些实际的代码让我朝着正确的方向开始吗？
谢谢大家：）
这应该会让您开始。注意：我还没有测试过这个。这是我的头顶。
/**
* 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增加了一。你应该能够自己解决这个问题。
好吧，玩了很长一段时间后，我终于让它按我想要的方式工作了。我使用$new_menu_buttons中的某些键来决定要做什么。例如：position告诉我它是在之后还是之前，parent告诉我在哪里搜索键，而slog给我键，用于添加的每个新菜单数组。array_splice不适合我，所以我使用array_merge方法，它非常有效。这是给其他遇到这个问题的人的。
function array_insert_buttons($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;
}
感谢你们的帮助：）
