Question

<?php
$startX = 2;
$startY = 5;

$fieldHeight = 6;
$fieldWidth = 6;

$player[2][5] = 1;


echo "<table>";
for ($y=$startY; $y<$fieldHeight+$startY+$fieldHeight; $y++) {
   echo "<tr>";
   for ($x=$startX; $x<$fieldWidth+$startX+$fieldWidth; $x++) {
       echo "<td>";
        if (isset($player[$x][$y])) {
            echo "UID: " . $player[$x][$y];
        } else {
            echo "(" . $x . ", " . $y . ")";
        }
       echo "</td>";
   }
   echo "</tr>";
}
echo "</table>";

输出：

正如你在左上角看到的那样，放置了UID：1，我希望它在中间，但我不知道如何......

我想我需要把坐标放在startX或者其他东西下面，但是如果有 - 坐标，我只会推出一个特定的测试，这可能吗？

Answer 1

好的

$startX = 2;
$startY = 5;

$player[2][5] = 1;

然后使用for和$startX作为循环的基本整数，请求两个$startY循环。因此，根据您的$player[2][5]条款，要打印的第一个项目为$player[$startX][$startY]（或if）。

演示您当前脚本出错的地方：更改$startX = 1;和$startY = 1，UID将打印在$ x = 2和$ y = 5。

将x，y坐标放在中间
