Hello everyone, I need some help to finish my code.

 

I'm working on a tictactoe program, 4x4. I have to make it so that the player will play against the pc, and it should also refresh the web page.

this is what i have so far

<?PHP
// If the game has already started, continue
// Else start a new game - X goes first
session_start();
$move = $HTTP_GET_VARS['move'];

// Reset if commanded
if($HTTP_GET_VARS['do'] == "reset") {
$move = "";
for($a = "0"; $a <= "3"; $a++) {
for($b = "0"; $b <= "3"; $b++) {
$value = "boardArray";
$value .= $a;
$value .= $b;
$_SESSION[$value] = "";
}
}
$_SESSION['whosTurn'] = "";
}

// Check for continuing or new game
if($move == "") {
// Start Game
// Initialize variables
$whosTurn = "X";
$gameRunning = "1";
$boardArray[0][0] = "";
$boardArray[0][1] = "";
$boardArray[0][2] = "";

$boardArray[1][0] = "";
$boardArray[1][1] = "";
$boardArray[1][2] = "";

$boardArray[2][0] = "";
$boardArray[2][1] = "";
$boardArray[2][2] = "";

// Set session variables
$_SESSION['boardArray'] = $boardArray;
$_SESSION['whosTurn'] = "X";
} else {
// Get board values
for($a = "0"; $a <= "3"; $a++) {
for($b = "0"; $b <= "3"; $b++) {
$value = "boardArray";
$value .= $a;
$value .= $b;
$boardArray[$a][$b] = $_SESSION[$value];
}
}

// Get game values and move coords
$whosTurn = $_SESSION['whosTurn'];
$coOrds = explode("-",$HTTP_GET_VARS['move']);
$x = $coOrds[0];
$y = $coOrds[1];

// Perform move, but check for refresh (F5) first
if($boardArray[$x][$y] == "") {$boardArray[$x][$y] = $whosTurn;} else {$refreshed = "1";}

// Stalemate function
function doStalemate() {
global $staleMate;
$staleMate = "1";
}

// Game win function
$gameWon = "0";
function doWin($whoWon,$wonWith1,$wonWith2,$wonWith3, $wonWith4) {
