我的 wordpress 网站被黑了，有人告诉我这段代码是做什么的吗?

所以我知道该网站被黑了.奇怪的是，当我访问该站点并查看源代码时，有时会出现这种情况.有时它不在那里.这让我担心这将很难摆脱.但这是代码.谁能给我一些见解?谢谢.

So I know the site was hacked. Strangely, when I visit the site, and look at the source code, sometime this shows up. Sometimes it isn't there. That makes me worried that this is going to be hard to get rid of. But here is the code. Can anyone give me some insight? Thank you.
