Question

我只使用cakePhp的函数query（）。该查询将返回如下数组：

array(
    (int) 0 => array(
        'cate' => array(
            'date' => '2016-12-05',
        ),
        'cate_detail' => array(
            'rel_data_category' => '11'
        ),
        'cate_item' => array(
            'price' => '150.000'
        ),
        'item' => array(
            'code' => '1'
        )
    ),
    (int) 1 => array(
        'cate' => array(
            'date' => '2016-12-05',
        ),
        'cate_detail' => array(
            'rel_data_category' => '10'
        ),
        'cate_item' => array(
            'price' => '250.000'
        ),
        'item' => array(
            'code' => '1'
        )
    ),
    (int) 2 => array(
        'cate' => array(
            'date' => '2016-12-06',
        ),
        'cate_detail' => array(
            'rel_data_category' => '10'
        ),
        'cate_item' => array(
            'price' => '250.000'
        ),
        'item' => array(
            'code' => '2'
        )
    ),
    (int) 3 => array(
        'cate' => array(
            'date' => '2016-12-06',
        ),
        'cate_detail' => array(
            'rel_data_category' => '10'
        ),
        'cate_item' => array(
            'price' => '250.000'
        ),
        'item' => array(
            'code' => '1'
        )
    )
)

现在，我想检查数组是否具有相同的cate.date和item.code将合并数组（在这种情况下是我的数组的元素0,1）。输出如下：

array(
    (int) 0 => array(
        'cate' => array(
            'date' => '2016-12-05',
        ),
        'cate_detail' => array(
            (int) 0 => array (
                'rel_data_category' => '11',
                'price' => '150.000'
            ),
            (int) 1 => array(
                'rel_data_category' => '10',
                'price' => '250.000'
            )
        ),
        'item' => array(
            'code' => '1'
        )
    ),
    (int) 1 => array(
        'cate' => array(
            'date' => '2016-12-06',
        ),
        'cate_detail' => array(
            (int) 0 => array (
                'rel_data_category' => '10'
                'price' => '250.000'
            )
        ),
        'item' => array(
            'code' => '2'
        )
    ),
    (int) 2 => array(
        'cate' => array(
            'date' => '2016-12-06',
        ),
        'cate_detail' => array(
            (int) 0 => array (
                'rel_data_category' => '10'
                'price' => '250.000'
            )
        ),
        'item' => array(
            'code' => '1'
        )
    )
)

请帮忙！

要做到这一点

首先声明一个变量，稍后您将存储新的合并数组数据

$filter_data = array();

然后循环现有的数组

foreach($items as $item) {

    // do somethind

然后创建一个函数，检查新数组中是否存在相同date和code的项目

    // checker
   if (!checkExist($item['cate']['date'], $item['item']['code'])) {

为稍后将附加到新数组的临时数据创建一个变量

    $data = array(
       'cate' => $item['cate'],
       'item' => $item['item']
     );

然后再次创建循环，它将追加具有相同内容的所有索引项cate_detail和cate_item 来自父循环的date和code

}
}

所以你的代码就像这样

$items = array(
    (int) 0 => array(
        'cate' => array(
            'date' => '2016-12-05',
        ),
        'cate_detail' => array(
            'rel_data_category' => '11'
        ),
        'cate_item' => array(
            'price' => '150.000'
        ),
        'item' => array(
            'code' => '1'
        )
    ),
    (int) 1 => array(
        'cate' => array(
            'date' => '2016-12-05',
        ),
        'cate_detail' => array(
            'rel_data_category' => '10'
        ),
        'cate_item' => array(
            'price' => '250.000'
        ),
        'item' => array(
            'code' => '1'
        )
    ),
    (int) 2 => array(
        'cate' => array(
            'date' => '2016-12-06',
        ),
        'cate_detail' => array(
            'rel_data_category' => '10'
        ),
        'cate_item' => array(
            'price' => '250.000'
        ),
        'item' => array(
            'code' => '2'
        )
    ),
    (int) 3 => array(
        'cate' => array(
            'date' => '2016-12-06',
        ),
        'cate_detail' => array(
            'rel_data_category' => '10'
        ),
        'cate_item' => array(
            'price' => '250.000'
        ),
        'item' => array(
            'code' => '1'
        )
    )
);

$filter_data = array();

foreach($items as $item) {
   if (!checkExist($item['cate']['date'], $item['item']['code'])) {
     $data = array(
       'cate' => $item['cate'],
       'item' => $item['item']
     );
     foreach($items as $detail) {
       if ($detail['cate']['date'] == $item['cate']['date'] &&
           $detail['item']['code'] == $item['item']['code']) {
         $data['cate_detail'][] = array(
           'rel_data_category' => $detail['cate_detail']['rel_data_category'],
           'price' => $detail['cate_item']['price']
         ); 
       }
     }
     $filter_data[] = $data;
   }
}

function checkExist($date, $code){
   global $filter_data;
   foreach($filter_data as $data) {
     if ($data['cate']['date'] == $date && 
         $data['item']['code'] == $code) {
       return true;
     }
   }
   return false;
}

pr($filter_data);
