What's yours? MONGO Manager?
You see how he wrote it.

is a mongoweb management address, I read a lot of writing, as if the link is so written, do not know why I made a mistake, so put out the structure of the database, I think this can be expressed more clearly

$DSN = "MONGODB://LOCALHOST:27017/ADMIN:ADMIN/AAA";
$m =new mongoclient ($DSN);
There's no error.
