Lets say your account database structure is like this :

Код:

users/userName.ini

So when a user types say, "/check test"
Then you will check whether a file like this exits or not :

Код:

users/test.ini

If not then send the player a message like "no such player in database!"

If yes then load the player info like you load when player logs in. Only difference: load it in different variable.
When i used to use ini systems what i did was that I used to declare player info variable like this :

Код:

new playerInfo[MAX_PLAYERS + 1];

See the "+1" here? I used to load offline player info in this extra index.
