This is how it should be, I've explained everything with comments.

PHP код:

CMD:sethit(playerid, params[])
{
     new receiver, amount;
     if (!sscanf(params, "ui", receiver, amount) //You want to use "u" instead of "i" because that is the sscanf specifier for playerid
     {
         if(!IsPlayerConnected(receiver)) //Making sure the player is connected. 
                    return SendClientMessage(playerid, -1, "That player isn't connected!"); 
          new INI:File = INI_Open(UserPath(receiver)); //Getting the userpath of the playerid that sscanf got
          INI_SetTag(File, "data"); //Setting the tag so it goes underneath data and not above. 
          INI_WriteInt(File,"Hit",amount);
          INI_Close(File);
     }
}
