PHP - RPS - 'Multiplayer' rock, paper, scissors mini game - How to store and pass variables? -

i have made structure of game (i can play vs bot), want make player vs player game. how store , pass variables then? should store in database (one table game id, 1 'move' id) or there simpler way? not intent keep score count or store next time same player want's play again.

here code have far (the player vs bot/ structure of game. not include form , other html on page):

$x = $_post['x']; $y = rand(1, 3); $a = $x-$y+3; $r = fmod($a, 3);  if ($r == 0) {     echo 'draw!'; } elseif ($r == 1) {     echo 'you won!'; } elseif ($r == 2) {     echo 'you lost!'; } else {     echo 'an error occurred!'; } 

if want see full script, please let me know.

my idea of database , tables:

table: users  userid    username    (i don't include email, password , salt here...) 1         espen 2         test  table: games  gameid    participant1 participant2 winner 1         1            2            1 1         1            2            2  table: moves  moveid    gameid       userid       move 1         1            1            2 2         1            2            1 3         2            1            3 4         2            2            1 

values of moves: 1-rock, 2-paper, 3-scissors
