Create a forloop to check if the player is connected.

PHP код:

forward payday(playerid);
public payday(playerid)
{
 for(new i = 0; i < MAX_PLAYERS; i++)
    {
    if(IsPlayerConnected(i))// continue;
    {
    GivePlayerMoney(i, 1000);
    SendClientMessage(i, COLOR_GREEN, "_______ BANK OF LOS SANTOS _______ ");
    SendClientMessage(i, COLOR_GREEN, "BANK:{FFFFFF} You've received 500$ from the goverment.");
    SendClientMessage(i, COLOR_GREEN, "___________________________________");
    GameTextForPlayer(i, "~w~PAYDAY, USD 500.", 5000, 4);
    SetTimerEx("payday", 560, true, "i", playerid);
    printf("SERVER: Payday has been executed. :)");
    return 1;
}
