What are some efficient methods for checking win conditions in games like TicTacToe or 4gewinnt using PHP?

In games like TicTacToe or 4gewinnt, checking win conditions involves examining the game board to see if a player has formed a winning combination of moves. One efficient method for checking win conditions is to iterate through the rows, columns, and diagonals of the game board to see if any of them contain a winning combination. This can be done by comparing the values in the cells of the game board to determine if they match. 

```php
function checkWin($board, $player) {
    // Check rows
    for ($i = 0; $i < 3; $i++) {
        if ($board[$i][0] == $player && $board[$i][1] == $player && $board[$i][2] == $player) {
            return true;
        }
    }

    // Check columns
    for ($i = 0; $i < 3; $i++) {
        if ($board[0][$i] == $player && $board[1][$i] == $player && $board[2][$i] == $player) {
            return true;
        }
    }

    // Check diagonals
    if ($board[0][0] == $player && $board[1][1] == $player && $board[2][2] == $player) {
        return true;
    }
    if ($board[0][2] == $player && $board[1][1] == $player && $board[2][0] == $player) {
        return true;
    }

    return false;
}
```

This function takes a 2D array representing the game board and a player value as input, and checks for win conditions by examining rows, columns, and diagonals. If a winning combination is found, the function returns true, otherwise it returns false.
