pawn Code:

#include foreach // For Iterator
new Iterator:LSPD_Members<MAX_PLAYERS>;

CMD:factions(playerid, params[])
{
       Iter_Add(LSPD_Members, playerid ); // we added a player
       SendClientMessage(playerid, COLOR_BLUE, "(1)LSPD[Members: %d/45][Online ]",Iter_Count(LSPD_Members)); // Counted the members
       return 1;
}
to make an exit cmd use these to remove
//     Iter_Remove(LSPD_Members, playerid );
//     Iter_Clear(LSPD_Members);

not tested but i think its all you need "Correct me if i am wrong".
