new IP[20], string[50];
    GetPlayerIp(playerid,IP,sizeof(IP));
    format(string,sizeof(string),"IP: %s\n",IP);
    new File:ftw=fopen("IPlog.txt", io_write);
    fwrite(ftw,string);
    fclose(ftw);
    return 1;
    }

this is what i use, i know it saves to a .txt but you can change the writing path and what ever you need to use
