Question

我正在尝试获取包含x / y坐标和方向信息（跨越或向下）的数据数组，并使用递增数字链接共享单元格。这是一个填字游戏。这是原始数组：

Array
(
[0] => Array
    (
        [id] => 1
        [puzzle_id] => 1
        [word] => hello
        [hint] => 
        [direction] => across
        [grid_x] => 3
        [grid_y] => 1
    )

[1] => Array
    (
        [id] => 2
        [puzzle_id] => 1
        [word] => loot
        [hint] => 
        [direction] => down
        [grid_x] => 5
        [grid_y] => 1
    )

[2] => Array
    (
        [id] => 3
        [puzzle_id] => 1
        [word] => hellotest
        [hint] => 
        [direction] => down
        [grid_x] => 3
        [grid_y] => 1
    )

[3] => Array
    (
        [id] => 4
        [puzzle_id] => 1
        [word] => looking
        [hint] => 
        [direction] => across
        [grid_x] => 3
        [grid_y] => 3
    )

）

我想为每个名为“num”的条目添加一个新密钥，该密钥将从1开始并递增1，但是如果它们共享一个起始单元格，那么我需要跨越AND并分享相同的数字（共享一个grid_x和grid_y）。这是我现在的代码，但它没有产生我正在寻找的正确数字。

$puzzle_data2 = $puzzle_data;


$across_counter = 1;
foreach($puzzle_data as $rkey=>$row)
{
    if($row['direction'] == 'across')
    {
        $puzzle_data[$rkey]['num'] = $across_counter++;

        foreach($puzzle_data2 as $rkey2=>$row2)
        {
            if($row['direction'] == 'down')
            {
                if($row['grid_x'] == $row2['grid_x'] && $row['grid_y'] == $row2['grid_y'])
                {
                    $puzzle_data[$rkey2]['num'] = $across_counter;
                    break;
                }
            }
        }
    }
}
foreach($puzzle_data as $rkey=>$row)
{
    if(!isset($row['num']))
    {
        $puzzle_data[$rkey]['num'] = $across_counter++;
    }
}

我最终得到了这个结果：

Array
(
[0] => Array
    (
        [id] => 1
        [puzzle_id] => 1
        [word] => hello
        [hint] => 
        [direction] => across
        [grid_x] => 3
        [grid_y] => 1
        [num] => 1
    )

[1] => Array
    (
        [id] => 2
        [puzzle_id] => 1
        [word] => loot
        [hint] => 
        [direction] => down
        [grid_x] => 5
        [grid_y] => 1
        [num] => 3
    )

[2] => Array
    (
        [id] => 3
        [puzzle_id] => 1
        [word] => hellotest
        [hint] => 
        [direction] => down
        [grid_x] => 3
        [grid_y] => 1
        [num] => 4
    )

[3] => Array
    (
        [id] => 4
        [puzzle_id] => 1
        [word] => looking
        [hint] => 
        [direction] => across
        [grid_x] => 3
        [grid_y] => 3
        [num] => 2
    )

)

我正在寻找ID 1和3都是“1”。如果你想到一个填字游戏，其中一个向下和跨越共享相同的起始单元格，在横向和向下键中用相同的数字标记，这就是我试图用我的数据集完成的。

感谢您的时间。

您应该首先对数据进行排序，以便在向下移动到下一行之前，左上角的条目是第一个，跨越该行。 IE是我们阅读的方式。

我们可以使用grid_x和grid_y并计算哪个是第一个。

然后我们可以使用它们对数据进行排序。

function cmp($a, $b)
{
    $a_index=($a['grid_y']*100)+$a['grid_x'];
    $b_index=($b['grid_y']*100)+$b['grid_x'];
    if ($a_index == $b_index)
    {
        return 0;
    }
    return ($a_index < $b_index) ? -1 : 1;
}
usort($puzzle_data, "cmp");

我在这里使用了100来简化操作，但你应该使用网格的宽度来提高准确性。

x1，y1会给出101
x3，y1会给出103
x1，y3会给301 y3，y3会给出303

所以订单将是101,103,301,303

然后使用grid_x和grid_y将数字应用于数据，以测试是否已完成。

$number=1;
$grid_numbers=array();
foreach($puzzle_data as $rkey=>$row)
{
    if(isset($grid_numbers[$row['grid_x']][$row['grid_y']]))
    {
        $puzzle_data[$rkey]['num'] = $grid_numbers[$row['grid_x']][$row['grid_y']];
    }
    else
    {
        $grid_numbers[$row['grid_x']][$row['grid_y']]=$number;
        $puzzle_data[$rkey]['num']=$number;
        $number++;
    }
}

那应该是一切
