PHP код:

public OnPlayerText(playerid, text[])
{
    new string[144];
    if(text[0] == '@' && Account[playerid][Admin] >= 1)
    {
        format(string, sizeof(string), "** |Admin Chat| %s: %s **", IsPlayerName(playerid), text[1]);
        for(new i = 0, j = GetPlayerPoolSize(); i <= j; i++)
        {
            if(IsPlayerConnected(i) && Account[i][Admin] >= 1)
                SendClientMessage(i, 0x0AFFC9FF, string);
        }
        return 0;
    }
    if(text[0] == '!' && Account[playerid][Vip] >= 1)
    {
        format(string, sizeof(string), "~> |Vip Chat| %s: %s <~", IsPlayerName(playerid), text[1]);
        for(new i = 0, j = GetPlayerPoolSize(); i <= j; i++)
        {
            if(IsPlayerConnected(i) && Account[i][Vip] >= 1)
                SendClientMessage(i, 0xFF0099AA, string);
        }
        return 0;
    }
    new var = GetPlayerVirtualWorld(playerid), pl_color = GetPlayerColor(playerid);
    format(string, sizeof(string), "%s (%d): {FFFFFF}%s", IsPlayerName(playerid), playerid, text);
    for(new i = 0, j = GetPlayerPoolSize(); i <= j; i++)
    {
        if(!IsPlayerConnected(i) || GetPlayerVirtualWorld(i) != var) continue;
        SendClientMessage(i, pl_color, string);
    }
    return 0;
} 


You were using 'return' within a loop, which would result in the loop being broken after the first iteration. (Meaning if the loop started at 0, the loop would only iterate through player ID 0 and then would not continue)

Also, I've changed your loops to make use of the function 'GetPlayerPoolSize' which returns the highest player ID being used on your server.
