{
    new INI:File = INI_Open(UserPath(playerid));
    INI_SetTag(File,"Data");
    INI_WriteInt(File,"Cash",GetPlayerMoney(playerid));
    INI_WriteInt(File,"Admin",PlayerInfo[playerid][pAdmin]);
    INI_WriteInt(File,"Kills",PlayerInfo[playerid][pKills]);
    INI_WriteInt(File,"Deaths",PlayerInfo[playerid][pDeaths]);
    INI_WriteInt(File,"Score",GetPlayerScore(playerid));
    INI_WriteInt(File,"VIP",PlayerInfo[playerid][pVIP]);
    INI_Close(File);
        return 1;
} 


PHP код:

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
    switch(dialogid)
    {
        case DIALOG_REGISTER:
        {
            if (!response) return Kick(playerid);
            if(response)
            {
                if(!strlen(inputtext)) return SPD(playerid, DIALOG_REGISTER, DIALOG_STYLE_PASSWORD, ""COLOR_BELA"Registracja...",""COLOR_CRVENA"Ukucali ste neispravnu sifru.\n"COLOR_BELA"Ukucajte novu sifru da se registrujete.","Register","Izlaz");
                new INI:File = INI_Open(UserPath(playerid));
                INI_SetTag(File,"Data");
                INI_WriteInt(File,"Password",udb_hash(inputtext));
                INI_WriteInt(File,"Cash",0);
                INI_WriteInt(File,"Admin",0);
                INI_WriteInt(File,"Kills",0);
                INI_WriteInt(File,"Deaths",0);
                INI_WriteInt(File,"Score",0);
                INI_Close(File);
                SpawnPlayer(playerid);
                SpawnPlayer(playerid);
            }
        }
        case DIALOG_LOGIN:
        {
            if (!response) return Kick(playerid);
            if(response)
            {
                if(udb_hash(inputtext) == PlayerInfo[playerid][pPass])
                {
                    INI_ParseFile(UserPath(playerid), "LoadUser_Data", .bExtra = true, .extra = playerid);
                    GPM(playerid, PlayerInfo[playerid][pCash]);
                }
                else
                {
                    SPD(playerid, DIALOG_LOGIN, DIALOG_STYLE_PASSWORD,""COLOR_BELA"Login",""COLOR_CRVENA"Ukucali ste ne ispravnu sifru.\n"COLOR_BELA"Ukucajte sifru pa se ulogujte.","Login","Izlaz");
                }
