PHP код:

for(new x;x<sizeof(RentVehicle);x++)
    {
RentVehicle[x] //your codes with it.
    } 


PHP код:

IsRentVehicle(carid)
{
    for(new v = 0; v < sizeof(RentVehicle); v++)
    {
        if(carid == RentVehicle[v]) return 1;
    }
    return 0;
} 


You just need to code something like this, to define all RentVehicle at once

After that , OnPlayerEnterVehicle :

PHP код:

(use "else" if there many already given )if(RentVehicle(vehicleid))
        {
//your codes 
            
        }
