If you want to use that array per player to store 5 objects each per player:

Code:

new objects[MAX_PLAYERS][5];

cmd:object(playerid, params[])
{
    objects[playerid][0] = createplayerobjectxxx
    objects[playerid][1] = createplayerobjectxxx
    objects[playerid][2] = createplayerobjectxxx
    objects[playerid][3] = createplayerobjectxxx
    objects[playerid][4] = createplayerobjectxxx

    return 1;
}

When player 3 uses this command, the server will have the value "3" for the "playerid" variable and will simply use it as a reference to access the array.
So it will create all 5 objects for player 3 in this array as if you had typed this:

Code:

new objects[MAX_PLAYERS][5];

cmd:object(playerid, params[])
{
    objects[3][0] = createplayerobjectxxx
    objects[3][1] = createplayerobjectxxx
    objects[3][2] = createplayerobjectxxx
    objects[3][3] = createplayerobjectxxx
    objects[3][4] = createplayerobjectxxx

    return 1;
}

The same will happen for player 27.
The server will simply paste "27" as the first index of the array.
