PHP Web Trojan scanner code sharing, Phpweb Trojan scanner

No nonsense, just paste the code.

The code is as follows:

The above code is the PHP Web Trojan scanner code sharing, this article with comments, there is not clear welcome to my message, I believe that the implementation method is more than one, welcome to share a lot of different ways to achieve.
