将X，Y坐标在中间

<?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>";

将输出：将X，Y坐标在中间

正如你可以在左上角看到，UID：1被放置，我希望它在中间，但我不不知道如何...

我想我会需要做的坐标，在startX或东西下面，但如果有 - 坐标，我只是推出一个具体的测试，而不是这是可能的？

'$ Y <$ fieldHeight + $ startY + $打印fieldHeight' ...为什么添加fieldHeight两次（并且在X calc中为fieldWidth同上）？ –

这是一个愚蠢的举动，以尝试自己修复它：P – John

'在中间' - 在什么中间？ – fredley

好了，所以

$startX = 2; 
$startY = 5; 

$player[2][5] = 1;

你然后要求使用$startX和$startY作为循环基地整数2个for循环。因此，根据您的if条款，要打印的第一项将是$player[2][5]（或$player[$startX][$startY]）。

演示你到哪儿去了什么问题与您当前的脚本：更改$startX = 1;和$startY = 1和UID将在$ X = 2和$ Y = 5
