WordPress网站创建主题后可以设置用户在后台发布文章，但是对于恶意攻击网站的用户来说，可能会在后台进行不安全操作，为了保护WordPress后台安全性需要屏蔽用户在后台不可操作的功能。
将下方代码添加进你正在使用的WordPress主题的functions.php中：
//屏蔽后台无用项
function remove_menus() {
global $menu;
$restricted = array(
__(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’Dashboard\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’),
__(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’Posts\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’),
__(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’Tools\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’),
__(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’Settings\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’),
__(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’Comments\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’),
__(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’Plugins\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’)
);
end ($menu);
while (prev($menu)){
$value = explode(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,$menu[key($menu)][0]);
if(strpos($value[0], \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'<\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’) === FALSE) {
