Remote Execution example (Arma 3)

// Some client function (before cleanup)
[getPlayerUID player,profileName,CASH,_bank,player] remoteExecCall ["DB_fnc_insertRequest",RSERV];

// Some client function (after cleanup)
0 remoteExecCall ["DB_fnc_insertRequest",2];

// Function on the server
DB_fnc_insertRequest = {
    // Ignore headless clients
    if (remoteExecutedOwner isEqualTo 0) exitWith {}; // headless client

    // Let server determine source of call by itself, not by arbitrary data.
    private _players = allPlayers select {(owner _x) isEqualTo remoteExecutedOwner};
    if (_players isEqualTo []) exitWith {};
    private _player = _players select 0;
    private _uid = getPlayerUID _player;
    private _name = _player getVariable['realname','none'];

    // ... whatever your code is supposed to do here, no client data input involved at any point.
