Question

我正在尝试创建一个多维数组，其中包含一个包含一些信息的索引，这些项应该链接到它各自的索引。

类似的东西：

Category-01 (Image, url1, url2)
- 01 Product (name, url1, url2, url3)
- 02 Product (name, url1, url2, url3)
- 03 Product (name, url1, url2, url3)
Category-02 (Image, url1, url2)
- 04 Product (name, url1, url2, url3)
- 05 Product (name, url1, url2, url3)
- 06 Product (name, url1, url2, url3)

我到目前为止（更改我用作基础的文件）是：

<?php
$categories = array( 
    "01" => array( 
        array("name" => "01", "mirror1" => "#URL011", "mirror2" => "#URL021", "mirror3" => "#URL031",), 
        array("name" => "02", "mirror1" => "#URL012", "mirror2" => "#URL022", "mirror3" => "#URL032",), 
        array("name" => "03", "mirror1" => "#URL013", "mirror2" => "#URL023", "mirror3" => "#URL033",), 
    ), 
    "02" => array( 
        array("name" => "04", "mirror1" => "#URL01", "mirror2" => "#URL02", "mirror3" => "#URL03",), 
        array("name" => "05", "mirror1" => "#URL01", "mirror2" => "#URL02", "mirror3" => "#URL03",), 
    ),
    "03" => array( 
        array("name" => "06", "mirror1" => "#URL01", "mirror2" => "#URL02", "mirror3" => "#URL03",), 
        array("name" => "07", "mirror1" => "#URL01", "mirror2" => "#URL02", "mirror3" => "#URL03",), 
    ),
); 
// Setup the preprocessing. 
$numColumns = 99; 
$columnLength = array(); 
$columnData = array(); 
for ($i = 0; $i <= $numColumns; $i++)  
{ $columnLength[] = 0; $columnData[] = ''; } 
// Sort the category array 
ksort($categories); 
// Process our data 
foreach ($categories as $cname => $subcats) { 
    $minLength = $columnLength[0]; 
    $minIndex = 0; 
    for ($i = 1; $i < $numColumns; $i++) { 
        if ($columnLength[$i] < $minLength) { 
            $minLength = $columnLength[$i]; 
            $minIndex = $i; 
        } 
    } 
    $columnLength[$minIndex] += 1 + count($subcat); 
    $columnData[$minIndex] .= '- Categoria '.$cname; 
    foreach($subcats as $subcat) { 
        $columnData[$minIndex] .= 'Produto '.$subcat['name'].' | [<a title="Produto URL01.'.$subcat['name'].'" href="'.$subcat['mirror1'].'">URL01</a>] - [<a title="Produto URL02.'.$subcat['name'].'" href="'.$subcat['mirror2'].'">URL02</a>] - [<a title="Produto URL03.'.$subcat['name'].'" href="'.$subcat['mirror3'].'">URL03</a>]<br/>';


    };
};
// Display our data 
for ($i = 0; $i < $numColumns; $i++) { 
    echo $columnData[$i]; 
} 
?>

PS：我还在学习，我是php的新手。

我会做的是这样的事情：

$categories = array( 
    "Cat" => "01", "Image" => "image_url", "cat_link1" => "#CATURL01", "cat_link2" => "#CATURL02" => array( 
        array("name" => "01", "mirror1" => "#URL011", "mirror2" => "#URL021", "mirror3" => "#URL031",), 
        array("name" => "02", "mirror1" => "#URL012", "mirror2" => "#URL022", "mirror3" => "#URL032",), 
        array("name" => "03", "mirror1" => "#URL013", "mirror2" => "#URL023", "mirror3" => "#URL033",), 
    ), 
    "Cat" => "02", "Image" => "image_url", "cat_link1" => "#CATURL01", "cat_link2" => "#CATURL02" => array( 
        array("name" => "04", "mirror1" => "#URL01", "mirror2" => "#URL02", "mirror3" => "#URL03",), 
        array("name" => "05", "mirror1" => "#URL01", "mirror2" => "#URL02", "mirror3" => "#URL03",), 
    ),
    "Cat" => "03", "Image" => "image_url", "cat_link1" => "#CATURL01", "cat_link2" => "#CATURL02" => array( 
        array("name" => "06", "mirror1" => "#URL01", "mirror2" => "#URL02", "mirror3" => "#URL03",), 
        array("name" => "07", "mirror1" => "#URL01", "mirror2" => "#URL02", "mirror3" => "#URL03",), 
    ),
);

如果可以，请将结果显示为：

Category-01 (Image)
- 01 Product (name, url1, url2, url3)
- 02 Product (name, url1, url2, url3)
- 03 Product (name, url1, url2, url3)
catURL1, catURL2
Category-02 (Image)
- 04 Product (name, url1, url2, url3)
- 05 Product (name, url1, url2, url3)
- 06 Product (name, url1, url2, url3)
catURL1, catURL2

但是脚本不能正常工作，它会显示产品和信息，但不能将信息放在类别/索引上而不是标题上。

提前感谢您的帮助。

您必须通过向每个类别添加Products值，将产品嵌套在类别中。它将包含产品列表。数组看起来像这样：

$categories = array(
    "01" => array(
        "Image" => "...",
        "url1" => "...",
        "url2" => "...",
        "Products" => array(
            array("name" => "...", "url1" => "...", "url2" => "...", "url3" => "..."),
            // and so on the Products...
        )
    ),
    // and so on the Categories...
);

此数组的处理方式略有不同，但请注意foreach如何迭代$cat['Products']：

foreach ($categories as $cname => $cat)
{
    // here you raech the data of the category by $cat ...

    foreach ($cat['Products'] as $subcat)
    {
        // here you reach the data of the product by $subcat ...
    }
}

多维数组，包含数组父子的信息
