帮我找到29行还是什么的无效代码，怎么删除或不用删除怎么修改

Answer 1

29行应该是：foreach (glob(PUN_ROOT.'addons/*.php') as $addon_file)

目测：glob(PUN_ROOT.'addons/*.php') 返回了false，而不是数组。

可以先加一步判断：

$files = glob(PUN_ROOT.'addons/*.php');
if(is_array($files)){
    foreach ($files as $addon_file)
    {
        $addon_name = 'addon_'.basename($addon_file, '.php');

        include $addon_file;
        $addon = new $addon_name;

        $addon->register($this);
    }
}

Parse error: syntax error, unexpected 'class' (T_CLASS), expecting function (T_FUNCTION) in /users/jixie824/www/include/addons.php on line 75

本来可以登录或者其他操作的，现在一改全是空白+上面的错误代码

追答

你修改错了，肯定丢了一个反花括号 “}”

你要实在不会改，就换一个改法。
把
foreach (glob(PUN_ROOT.'addons/*.php') as $addon_file)
改为
foreach ((array)glob(PUN_ROOT.'addons/*.php') as $addon_file)

追问

改了还是一样，空白+错误代码的 2个警告和一个致命错误

Answer 2

重新覆盖原有程序代码，不要用记事本修改
