I have found strange code in all my wordpress files.Some was stored it the error code files 400 thru 500 files. i read the forums in wordpress and thought like they did it was wordfence. Today I don’t think so because I just helped a customer remove 6k of it from his php site. Same code so I contacted my custom server farm support. Results: security says unknown but no threat”benign” was the word used. Engineering: No idea can’t find any function it does,but it came in through applications. So now I’m contacting you to see if you know what it could be. I have a copy of the code and I'm attaching a picture of it.
