如何获取客户端用户名php - 只获取localhost用户名

Question

Hi I am using the code below to retrieve client username on my website but it only works for me on localhost, other people connected remotely to the file its just finding nothing with no errors or anything.

exec("wmic /node:$_SERVER[REMOTE_ADDR] COMPUTERSYSTEM Get UserName", $user);
echo($user[1]);

What is the problem ?

Answer 1

For a remote system you may need to send administrator credentials, e.g.

exec("wmic /node:$_SERVER[REMOTE_ADDR] /user:administrator /password:mypassword COMPUTERSYSTEM Get UserName", $user);
echo($user[1]); 

I'd also research if safe to trust REMOTE_ADDR and use it in this way with wmic.

If you are using IIS and looking to get the remote users AD username, this may help: Can you get a Windows (AD) username in PHP?
