Question

我正在建造一个国际象棋游戏，随机将7个皇后牌放在棋盘上而不会相互击打。该板由7行7列构成。

我已经知道如何将女王放入阵列中。但现在我正在尝试绘制棋盘（使用类游戏中的方法showBoard）和其中“box”数组的值。因此，当数组发生变化时，它应该反映在棋盘上。下面是代码和数组。有人知道如何做到这一点？

索引

<?php

require_once '../core/init.php';

/* Init $game */
$game = new Game();

/* Init board */
$game->setBoard(7);

/* Set piece */
$game->setPiece();

/* Show chessboard (including real-time status of the boxes) */
echo $game->showBoard();

/* Debug tool */
echo "<pre>";
print_r($game);
echo "</pre>";
