I am not sure how the php library is so can't say XD.
Understanding and solving the MCI limits [inc examples in various languages]
Leechers/Non programmers move on. This isn't a source.
"There is no MCI 8 player limit!"
Read the following code until you get it.
Players is a collection which changes constantly as players join and leave. MCI is an array of 8 elements and always is. So when you have 9 players, you are trying to access the 9th element of MCI which doesn't exist which will give you an MCI exception.
"Ok so lets just change all Players.Count to MCI.NumC"
Well MCI.NumC at max can be 8. So if you have 9 players, that last player wont be updated.
"But it would send 8 and then 1!"
So you would be updating the first players stuff with the 9th players when you get the 1.
"Ok so what do we do?"
I did the simplest thing. I added the CompCar Packet struct to the clsPlayer structure. Here is an example of how I changed MCI.
So now we always have data for the cars in the clsPlayer structure. Now we can access the cars data anywhere. Unlike before were we could only access the cars data from the MCI thread. Now you can rewrite a lot of code and remove most of the MCI stuff and put it in different spots. No more waiting until MCI is executed to engage a target.
This fixes so many problems.
1. Not being able to access car data anywhere but the MCI thread.
2. Out of bounds error from Players being larger than MCI.
3. Lots more (brain fart)
I am working on this, just this should be enough to get ya started.

Players[idx].CompCar.AngVel = MCI.Info[i].AngVel; //They aren't structures so you cant serialize!
Players[idx].CompCar.Direction = MCI.Info[i].Direction;
Players[idx].CompCar.Heading = MCI.Info[i].Heading;
Players[idx].CompCar.Info = MCI.Info[i].Info;
Players[idx].CompCar.Lap = MCI.Info[i].Lap;
Players[idx].CompCar.Node = MCI.Info[i].Node;
Players[idx].CompCar.PLID = MCI.Info[i].PLID;
Players[idx].CompCar.Position = MCI.Info[i].Position;
Players[idx].CompCar.Speed = MCI.Info[i].Speed;

Players[idx].CompCar.Y = MCI.Info[i].Y;

take the username, search through connections till you find it. If you find it send them a message.
Simple check how close people are before dispatching the message.
This works on every server. Some servers require more then 1 person doing it. (CLC,WS.C,etc)
What download is the source included in?
I did, just waiting to write up an article. So leechers can't copy and paste.
Shaun, msg to connection uses 3 parameters. Msg to all uses 1.
Can you add barriers with LFS_External? Or insim for that matter?

Can playerid be 0? Or is it always non zero?
You get that error because MCI is 8 elements long no matter what. Player idx(cars on track) can go over 8. So when you have a loop going through Players it hits idx 8 but MCI doesn't have that so you are overflowing.
That is a terrible way to fix it. With that players 1-8 will only be able to engage eachother same with 9-16, 17-24 etc.
because the MCI packet sends a max of 8 players data. So if you have 9 people it send 2 packets. 1 with 8 and another with 1.

I guess I will look at the flags.
if you rent more then 1 car, the last person to rent will be effected by everyone that rented before (Fined, money,etc).
lol I rewrote your whole example dougie.
It goes a lot faster if you don't stick 1000 things in MCI receive :P.
I think I'll post an example of how I rewrote the command system in this section later. Anyone interested? It makes it a lot easier to add more commands and keep them organized.

Does the playerid change when they take over a vehicle?
my friend tried it on mutliple servers and it worked for him. Helps if you have more people doing it too. Its basically a dos.
Dedi server exploit [possible bug]
If a user holds down Ctrl+T for a min or so it will disconnect insim.
If you hold Ctrl+T for a minute it disconnects the insim from the server. Can you fix this?
Well here let me clarify what he was saying.
I switched to MySql just because it is easier to handle then flat files. Also I was getting annoyed that when a person have no cars it doesn't add them to Connections. (Causing many many problems with collisions from a person ingame not being in Connections)
Now there is a 8 Players limit (not connections).
What happens is when you have 9+ people on the track. you have a line like this
for (int i = 0; i < Players.Count; i++)
loop through MCI 9+ times when it itself has only 8 elements. giving you an index out of bounds of array error.
I fixed this by completely rewriting how you handle MCI. (Also my rewrite makes it run faster :P).
