PHP код:

switch (vehicleid)
{
    case PD_LSPDUND4, PD_LSPDUND5, PD_LSPDUND6, PD_LSPDUND7, PD_LSPDUND8, PD_LSPDUND9, PD_LSPDTAXI:
    {
        if(PInfo[playerid][pCop] <= 7)
        {
            new Float:x, Float:y, Float:z;
            GetPlayerPos(playerid, x, y, z);
            SetPlayerPos(playerid, x, y, z+1);
            SendClientMessage(playerid,0xAA3333AA, "You are not a Detective I");
        }
    }
} 


However, the way you are creating the vehicles is bad for this condition. You can create a custom function to create a vehicle and inside the function while creating those police vehicles (or whatever they are), you can assign a variable to them. For example; g_PoliceVehicle[vehicleid] = 1;

Then you can simply check if the variable is positive then eject the player without having to detect every created vehicle IDs.
