PHP код:

stock GetPlayerFreeVehicleId(playerid)
{
    for(new i; i < MAX_PLAYERVEHICLES; ++i)
    {
        if(PlayerVehicleInfo[playerid][i][pvModelId] == 0) return i;
    }
    if(PlayerInfo[playerid][pAdmin] == 99999)
    {
        MAX_PLAYERVEHICLES+1; // LINE 124708
    }
    else
    return -1;
}   // LINE 124712 


"MAX_PLAYERVEHICLES+1;" doesnt make any sense, because you dont initialise any value, you just add two numbers but you don't put that value to a variable. I guess what you want is to return that value:
