Something Like:

PHP код:

OnPlayerEnterVehicle
{
     CountPlayersInVehicle(vehicleid, blabla
} 


And make a stock for CountPlayersInVehicle like:

PHP код:

forward CountPlayersInVehicle(vehicleid);
public CountPlayersInVehicle(vehicleid)
{
     PlayerInVehicle++;
} 


Or something like that above, Not entirely sure how it'd work but i'm sure it can be done if there isn't a function already.

Good Luck With It.
