Php 将值指定给多维数组以进行检查

我的问题是不用坐标来移动，我能分配数字和字母吗？这样我就可以用这些值移动了

编辑：我正在将线路板输出到HTML8x8表格

$square = array( //    A B C D E F G H     
               0 array(0,0,0,0,0,0,0,0),
               1 array(0,0,0,0,0,0,0,0),
               2 array(0,0,0,0,0,0,0,0),
               3 array(0,0,0,0,0,0,0,0),
               4 array(0,0,0,0,0,0,0,0),
               5 array(0,0,0,0,0,0,0,0),
               6 array(0,0,0,0,0,0,0,0),
               7 array(0,0,0,0,0,0,0,0),
);

因此，当用户输入：From:F1到：G2时，碎片会移动

我这样做不是更好吗

Array ( 'A' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'B' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'C' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'D' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'E' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'F' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'G' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 
        'H' => Array ( [0] => 0 [1] => 0 [2] => 0 [3] => 0 [4] => 0 [5] => 0 [6] => 0 [7] => 0 ) 

    ); 

解析

function parseSquareFrom() {
    if (strlen($square) != 2) {
    return FALSE;
    }

    $coords = array(ord('A') - ord($square[0]),
            $square[1] - 1);


    // Perform bounds-checking.
    if ($coords[0] < 0 || $coords[0] > 7 || $coords[1] < 0 || $coords[1] > 7) {
    return FALSE;
    }

    return $coords;
}
$coords = parseSquare($square);
if ($coords === FALSE) {
    // Invalid input, handle this case.
} else {
    $piece = $board[$coords[0]][$coords[1]]; // for example
}

或者是$piece=$board[$coords1[0]][$coords1[1]]；不能使用

是的，您可以这样做。您只需要确保能够使用某种算法移动到该区域，并确保在移动值时更改值

@您最近的评论： 如果您看一看这篇文章，其中有一节介绍多维数组，这对于参考非常有帮助。这应该对你有帮助。让我知道这是否解决了你的问题

是：将输入字符串解析为X，Y对。例如：

function parseSquare($square) {
    if (strlen($square) != 2) {
        return FALSE;
    }

    $coords = array(ord('A') - ord($square[0]),
                    $square[1] - 1);

    // Perform bounds-checking.
    if ($coords[0] < 0 || $coords[0] > 7 || $coords[1] < 0 || $coords[1] > 7) {
        return FALSE;
    }

    return $coords;
}

代表电路板的片段数组？我在帖子中编辑了数组，或者我需要在使用您发布的代码之前对数组进行循环，因为我已经在循环中创建了html表8x8 boardNo loops，请确保更新变量，使它们不会冲突。因此，使用

$square

而不是

$board

，并将用户输入的方块存储在

$square

$piece=$board[$coords[0]][$coords[1]]；//例如，将其更改为$piece=$square[$coords[0]][$coords[1]]；//例如，没错。只要把变量映射成新的名称就行了。当我移动它们时，我该如何改变它们的值呢？我知道有一些数组函数

    $board[$coords1[0]-1][$coords1[1]+1] = $board[$coords[0]][$coords[1]];
    $board[$coords[0]][$coords[1]] = 0;

    //eating action
    $board[$coords1[0]][$coords1[1]] = 0;
    $board[$coords1[0]-2][$coords1[1]+2] = $board[$coords[0]][$coords[1]];

    //if player is 'up' then the value of $way is 1 so
      $board[$x+(-1*$way)][$y+(1*$way)] = $board[$coords[0]][$coords[1]]; // position 2,2 becomes 1,3
   //if player is not 'up' then the value of $way is -1 so
      $board[$x+(-1*$way)][$y+(1*$way)] = $board[$coords[0]][$coords[1]]; // position 2,2 becomes 3,1

function parseSquare($square) {
    if (strlen($square) != 2) {
        return FALSE;
    }

    $coords = array(ord('A') - ord($square[0]),
                    $square[1] - 1);

    // Perform bounds-checking.
    if ($coords[0] < 0 || $coords[0] > 7 || $coords[1] < 0 || $coords[1] > 7) {
        return FALSE;
    }

    return $coords;
}

$coords = parseSquare($square);
if ($coords === FALSE) {
    // Invalid input, handle this case.
} else {
    $piece = $board[$coords[0]][$coords[1]]; // for example
}
