Question

我有两个foreach循环，它的工作正常。但我需要不同格式的数据。请查看以下代码。

代码

$data['categories'] = array();
foreach ($allCategories as $result) {
        $data['categories'][] = array(
                'name' => $result['name'],
                'Cat_id' => $result['category_id']
        );
        $productData= $this->model_catalog_product->getProducts($productID);
        foreach ($productData as $singleProduct) {


            $data['categories'][] = array(
                'product_id'  => $singleProduct['product_id'],
                'thumb'       => $image,
                'name'        => $singleProduct['name'],
                'description' => utf8_substr(strip_tags(html_entity_decode($singleProduct['description'], ENT_QUOTES, 'UTF-8')), 0, $this->config->get('config_product_description_length')) . '..',
                'price'       => $price,
                'special'     => $special,
                'tax'         => $tax,
                'minimum'     => $singleProduct['minimum'] > 0 ? $singleProduct['minimum'] : 1,
                'rating'      => $rating,
                'href'        => $this->url->link('product/product', 'product_id=' . $singleProduct['product_id'])
            );

         }

    }

结果

Array
(
    [0] => Array
        (
            [name] => sweflora special
            [Cat_id] => 59
        )

    [1] => Array
        (
            [product_id] => 52
            [thumb] => http://localhost/swefloraProject/upload/image/cache/catalog/birthday/home-product-01-80x80.png
            [name] => gift flowers
            [description] => when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has ..
            [price] => $0.00
            [special] => 
            [tax] => $0.00
            [minimum] => 1
            [rating] => 0
            [href] => http://localhost/swefloraProject/upload/index.php?route=product/product&amp;product_id=52
        )

    [2] => Array
        (
            [name] => birthday
            [Cat_id] => 61
        )

    [3] => Array
        (
            [product_id] => 53
            [thumb] => http://localhost/swefloraProject/upload/image/cache/catalog/birthday/flower2-80x80.jpg
            [name] => test flower
            [description] => ..
            [price] => $86.00
            [special] => 
            [tax] => $86.00
            [minimum] => 1
            [rating] => 0
            [href] => http://localhost/swefloraProject/upload/index.php?route=product/product&amp;product_id=53
        )
  )

我想更改数组格式。目前它直接显示类别和产品。但我需要一个像这种格式的数组。

我使用了array_push和array_combine，但确实解决了这个问题。任何人都可以指导我如何转换为这种格式。感谢

基本上，我认为嵌套的foreach应该为每个类别的新内部数组添加元素。您无法完全您发布的结构，您可以将关键“产品”与多个对象相关联，但您可以构建嵌套的产品数组。所以我会尝试这个：


    foreach ($productData as $singleProduct) {
        $data['categories']['Products'][] = array(/* Your element */);

编辑：我们需要保持与类别的约束，所以我会这样做：

$i=0;
foreach ($allCategories as $result) {
    $data['categories'][$i] = array(
            'name' => "N",
            'Cat_id' => "C",
            'Products' => array()
    );
    $productData= $this->model_catalog_product->getProducts($productID);
    foreach ($productData as $singleProduct){
        $data['categories'][$i]['Products'][] = array(
            /* Your product */);

     }
$i++;
}

如何在php中设置多维foreach循环？
