* blackops_programmer *给出的答案中的代码检查用户是否可以保护页面.默认情况下，这将是sysops，但是可以从任何组中分配或删除该权限.

The code in the answer by *blackops_programmer* checks whether the user can protect pages. Per default, that would be sysops, but the permission can be assigned or removed from any group.

如果您要执行的操作取决于保护页面的权限，则检查权限是正确的方法(除非您应使用$ this-> getUser()，而不是$ wgUser). 但是，如果您确实要检查sysop组，请使用以下命令:

If what you want to do depends on the right to protect pages, then checking the permission is the correct way (except you should use $this->getUser(), not $wgUser). However, if you really want to check for the sysop group, use this:

if ( in_array( 'sysop', $this->getUser()->getEffectiveGroups() ) {
  echo 'Hello People';
}
