本文目录导读：
我来帮你实现一个PHP五子棋游戏,这里提供两种实现方式：
纯PHP控制台版本
<?php
class GomokuGame {
private $board = [];
private $size = 15;
private $currentPlayer = 1; // 1=黑棋, 2=白棋
public function __construct() {
$this->initBoard();
}
// 初始化棋盘
private function initBoard() {
for ($i = 0; $i < $this->size; $i++) {
for ($j = 0; $j < $this->size; $j++) {
$this->board[$i][$j] = 0;
}
}
}
// 下棋
public function placePiece($row, $col) {
if ($row < 0 || $row >= $this->size || $col < 0 || $col >= $this->size) {
return false;
}
if ($this->board[$row][$col] != 0) {
return false;
}
$this->board[$row][$col] = $this->currentPlayer;
// 检查是否胜利
if ($this->checkWin($row, $col)) {
return "玩家 " . ($this->currentPlayer == 1 ? "黑棋" : "白棋") . " 获胜！";
}
// 切换玩家
$this->currentPlayer = $this->currentPlayer == 1 ? 2 : 1;
return true;
}
// 检查胜利条件
private function checkWin($row, $col) {
$directions = [
[0, 1], // 水平
[1, 0], // 垂直
[1, 1], // 对角线
[1, -1] // 反对角线
];
foreach ($directions as $dir) {
$count = 1;
// 正方向
for ($i = 1; $i < 5; $i++) {
$newRow = $row + $dir[0] * $i;
$newCol = $col + $dir[1] * $i;
if ($this->isValidPos($newRow, $newCol) &&
$this->board[$newRow][$newCol] == $this->currentPlayer) {
$count++;
} else {
break;
}
}
// 反方向
for ($i = 1; $i < 5; $i++) {
$newRow = $row - $dir[0] * $i;
$newCol = $col - $dir[1] * $i;
if ($this->isValidPos($newRow, $newCol) &&
$this->board[$newRow][$newCol] == $this->currentPlayer) {
$count++;
} else {
break;
}
}
if ($count >= 5) {
return true;
}
}
return false;
}
// 检查位置是否有效
private function isValidPos($row, $col) {
return $row >= 0 && $row < $this->size &&
$col >= 0 && $col < $this->size;
}
// 显示棋盘
public function displayBoard() {
echo " ";
for ($i = 0; $i < $this->size; $i++) {
printf("%2d ", $i);
}
echo "\n";
for ($i = 0; $i < $this->size; $i++) {
printf("%2d ", $i);
for ($j = 0; $j < $this->size; $j++) {
$piece = $this->board[$i][$j];
if ($piece == 1) {
echo "● ";
} elseif ($piece == 2) {
echo "○ ";
} else {
echo "· ";
}
}
echo "\n";
}
}
// 获取当前玩家
public function getCurrentPlayer() {
return $this->currentPlayer;
}
// 检查棋盘是否已满
public function isBoardFull() {
for ($i = 0; $i < $this->size; $i++) {
for ($j = 0; $j < $this->size; $j++) {
if ($this->board[$i][$j] == 0) {
return false;
}
}
}
return true;
}
}
// 游戏主循环（控制台版本）
function playConsoleGame() {
$game = new GomokuGame();
echo "=== PHP五子棋游戏 ===\n";
echo "输入行列坐标（如：7 7），q退出\n\n";
while (true) {
$game->displayBoard();
$player = $game->getCurrentPlayer();
echo "\n当前玩家：" . ($player == 1 ? "黑棋(●)" : "白棋(○)") . "\n";
echo "请输入坐标：";
$input = trim(fgets(STDIN));
if ($input == 'q' || $input == 'Q') {
echo "游戏结束\n";
break;
}
$coords = explode(' ', $input);
if (count($coords) != 2) {
echo "输入格式错误，请输入两个数字\n";
continue;
}
$row = (int)$coords[0];
$col = (int)$coords[1];
$result = $game->placePiece($row, $col);
if ($result === false) {
echo "无效位置，请重新输入\n";
} elseif (is_string($result)) {
$game->displayBoard();
echo "\n" . $result . "\n";
echo "游戏结束！\n";
break;
}
if ($game->isBoardFull()) {
echo "棋盘已满，平局！\n";
break;
}
}
}
// 运行控制台版本
// playConsoleGame();
?>
Web版本（HTML + PHP）
<?php
session_start();
class GomokuWeb {
private $size = 15;

if (!isset($_SESSION['board']) || isset($_POST['new_game'])) {

return false;

$board = $_SESSION['board'];
if ($board[$row][$col] != 0) {
return false;
}
$board[$row][$col] = $_SESSION['current_player'];
$_SESSION['board'] = $board;
if ($this->checkWin($board, $row, $col, $_SESSION['current_player'])) {
$_SESSION['game_over'] = true;
$_SESSION['winner'] = $_SESSION['current_player'];
} else {
$_SESSION['current_player'] = $_SESSION['current_player'] == 1 ? 2 : 1;
}
return true;
}
private function checkWin($board, $row, $col, $player) {
$directions = [[0,1], [1,0], [1,1], [1,-1]];
foreach ($directions as $dir) {
$count = 1;
for ($i = 1; $i < 5; $i++) {
$r = $row + $dir[0] * $i;
$c = $col + $dir[1] * $i;
if ($r >= 0 && $r < 15 && $c >= 0 && $c < 15 && $board[$r][$c] == $player) {
$count++;
} else break;
}
for ($i = 1; $i < 5; $i++) {
$r = $row - $dir[0] * $i;
$c = $col - $dir[1] * $i;
if ($r >= 0 && $r < 15 && $c >= 0 && $c < 15 && $board[$r][$c] == $player) {
$count++;
} else break;
}
if ($count >= 5) return true;
}
return false;
}
public function renderBoard() {
$board = $_SESSION['board'];
echo "<table class='board'>";
for ($i = 0; $i < 15; $i++) {
echo "<tr>";
for ($j = 0; $j < 15; $j++) {

}
}
// 初始化游戏
$game = new GomokuWeb();
$game->initBoard();
// 处理移动
if (isset($_POST['move']) && !$_SESSION['game_over']) {
$row = (int)$_POST['row'];

使用方法
控制台版本：
php gomoku_console.php
Web版本：
- 将代码保存为
gomoku.php - 放到你的Web服务器（Apache/Nginx）目录
- 浏览器访问该文件
主要功能
✅ 基础功能：
- 15×15的标准棋盘
- 黑白棋对战
- 自动判断胜负
- 玩家轮流下棋
✅ 增强功能：
- 简单的界面优化
- 会话管理（可以保存游戏状态）
- 重新开始功能
- 胜负提示
这个实现包含了五子棋的核心逻辑,包括落子、胜负判断和玩家轮换，你可以根据需要进一步扩展，比如添加AI对战、悔棋功能、在线对战等。
