好的，我正在努力解决一个项目问题。它在php中扫雷，但在游戏的基础上，我无法获得不同的单元块来存储他们的信息。香港专业教育学院尝试使用会话和获取，但我似乎无法弄清楚如何存储信息或在何处放置代码。以下是基本游戏代码：任何想法？
更新：我非常感谢我一直试图解决这个问题的帮助。我不确定在哪里放置一些会话值。这对我来说不合适：

<body>
<?php
// ~~~~~~~~~ VARIABLES ~~~~~~~~~~
session_start();
$_SESSION[$piece] = $piece;
$default_board = "default_board";
$filename = "currentproject.php";
$width = "20px";
$height = "20px";
$y_coord = 50;
$how_many_spots = 25;
echo "<table border=1>";
$_SESSION['clicks'] = array();
for ($y=24;$y!=0;--$y) {
$y_coord += $height;
$x_coord = 50;
for ($x=24;$x!=0;--$x){
$x_coord += $width; $cell_sum = $x + $y; $remainder = $cell_sum%2; // some math
if (isset($piece[$x][$y])) {
$background_color = "#991122"; //shows a mine
} else if ($remainder == 0) {
$background_color = "#CCCCCC";
} else $background_color = "#AAAAAA";
echo "<div onclick=\"javascript:document.location.href='$filename?xcord=$x&ycord=$y';\" style=\"border: 1px solid black; background-color: $background_color; position: absolute;left: $x_coord; top: $y_coord; width: $width; height: $height;\">";
echo "</div>";
$_SESSION['clicks'][$xcord][$ycord] = False;
$_SESSION['clicks'][$_GET['xcord']][$_GET['ycord']] = True;
// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ MINES GO HERE ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
while ($how_many_spots!=0){
$i = rand(1,24);
$e = rand(1,24);
if (!isset($piece[$i][$e])){
$piece[$i][$e] = "mine";
--$how_many_spots;
}
}
}
print ("<br>");

$_GET['xcord'] = $xcord;
$_GET['ycord'] = $ycord;
?>

答案 0 :(得分：0)
可以使用$_SESSION和$_GET变量来完成。以下是一个工作示例。锻炼很有趣，我希望它有所帮助。请注意，交替灰色框的代码不是很正确，我没有修复它。我还添加了网格大小和地雷数量的选项，因为使用25 x 25网格玩625个盒子和25个地雷 - 这是一个相当困难的生存机会。我将网格默认为4x4（我喜欢获胜），你当然可以改变它。
