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,
'sub_buttons' => array(
),
'is_last' => $context['right_to_left'],
),
'help' => array(
'title' => $txt['help'],
'href' => $scripturl . '?action=help',
'show' => true,
'sub_buttons' => array(
),
),
'search' => array(
'title' => $txt['search'],
'href' => $scripturl . '?action=search',
'show' => $context['allow_search'],
'sub_buttons' => array(
),
),
'admin' => array(
'title' => $txt['admin'],
'href' => $scripturl . '?action=admin',
'show' => $context['allow_admin'],
'sub_buttons' => array(
'featuresettings' => array(
'title' => $txt['modSettings_title'],
'href' => $scripturl . '?action=admin;area=featuresettings',
'show' => allowedTo('admin_forum'),
),
'packages' => array(
'title' => $txt['package'],
'href' => $scripturl . '?action=admin;area=packages',
'show' => allowedTo('admin_forum'),
),
'errorlog' => array(

),
'permissions' => array(

'href' => $scripturl . '?action=admin;area=permissions',
'show' => allowedTo('manage_permissions'),
'is_last' => true,
),
),
),
'moderate' => array(
'title' => $txt['moderate'],
'href' => $scripturl . '?action=moderate',
'show' => $context['allow_moderation_center'],
'sub_buttons' => array(
'modlog' => array(
'title' => $txt['modlog_view'],
'href' => $scripturl . '?action=moderate;area=modlog',
'show' => !empty($modSettings['modlog_enabled']) && !empty($user_info['mod_cache']) && $user_info['mod_cache']['bq'] != '0=1',
),
'poststopics' => array(
'title' => $txt['mc_unapproved_poststopics'],
'href' => $scripturl . '?action=moderate;area=postmod;sa=posts',

),
'reports' => array(
'title' => $txt['mc_reported_posts'],
'href' => $scripturl . '?action=moderate;area=reports',
'show' => !empty($user_info['mod_cache']) && $user_info['mod_cache']['bq'] != '0=1',
'is_last' => true,
),
),
),
'profile' => array(
'title' => $txt['profile'],
'href' => $scripturl . '?action=profile',
'show' => $context['allow_edit_profile'],
'sub_buttons' => array(
'summary' => array(
'title' => $txt['summary'],
'href' => $scripturl . '?action=profile',
'show' => true,
),
'account' => array(
'title' => $txt['account'],
'href' => $scripturl . '?action=profile;area=account',
'show' => allowedTo(array('profile_identity_any', 'profile_identity_own', 'manage_membergroups')),
),
'profile' => array(
'title' => $txt['forumprofile'],
'href' => $scripturl . '?action=profile;area=forumprofile',
'show' => allowedTo(array('profile_extra_any', 'profile_extra_own')),
'is_last' => true,
),
),
),
'pm' => array(
'title' => $txt['pm_short'],
'href' => $scripturl . '?action=pm',
'show' => $context['allow_pm'],
'sub_buttons' => array(
'pm_read' => array(
'title' => $txt['pm_menu_read'],
'href' => $scripturl . '?action=pm',
'show' => allowedTo('pm_read'),
),
'pm_send' => 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'),
),
'post' => array(
'title' => $txt['calendar_post_event'],
'href' => $scripturl . '?action=calendar;sa=post',
'show' => allowedTo('calendar_post'),
'is_last' => true,
),
),
),
'mlist' => array(
'title' => $txt['members_title'],
'href' => $scripturl . '?action=mlist',
'show' => $context['allow_memberlist'],
'sub_buttons' => array(
'mlist_view' => array(
'title' => $txt['mlist_menu_view'],
'href' => $scripturl . '?action=mlist',
'show' => true,
),
'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，我希望能够在上面的数组中的任何键之前或之后将数组插入其中。我要插入的数组如下所示:
$new_menu_buttons['testing'] = array(
'title' => $txt['testing'],
'href' => $scripturl . '?action=testing',
'show' => true,
'target' => '_self',
'active_button' => false,
);
有人建议使用函数来处理此问题以及要使用的方法，但是我不确定如何执行此操作，因为它们也需要这些函数的偏移量。这是有人建议我为此使用的功能结构，而不是仅在需要时调用这些功能:
function array_insert_before($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
}
因此，我希望能够像这样调用函数:
如果需要在 key “home”之后输入，请指定:
$menu_buttons = array_insert_after($buttons, 'home', $new_menu_buttons);
如果需要在 key “home”之前输入，请指定:
$menu_buttons = array_insert_before($buttons, 'home', $new_menu_buttons);
基本上，我确实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？有人愿意在正确的方向上以一些实际的代码开始我吗？谢谢你们 :)
最佳答案
这应该可以帮助您入门。注意:我尚未对此进行测试。它不在我的头上。
/**
* 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, $pos)
);
}
array_insert_after()几乎相同，只是$pos增加了一个。您应该能够自己弄清楚这一点。关于PHP-需要帮助，将数组插入给定键的关联数组中，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/6501845/
