Question

我的数组是这样的：

   $arr = array(
    array(
        'id' => 1,
        'hotel_code' => 'PHCEB_00001',
        'hotel_name' => 'Cebu Hotel',
        'address' => 'Cebu Address',
        'hotel_title' => 'LOCATION DETAIL',
        'hotel_description' => '7 kms to city centre 2 kms to the airport 60 kms to the airport 6 km to the nearest station ',
    ),
    array(
        'id' => 1,
        'hotel_code' => 'PHCEB_00001',
        'hotel_name' => 'Cebu Hotel',
        'address' => 'Cebu Address',
        'hotel_title' => 'ROOMS',
        'hotel_description' => 'Rooms with elegant set up viewing our beautiful natural landscape garden, private balcony'
    ),
    array(
        'id' => 1,
        'hotel_code' => 'PHCEB_00001',
        'hotel_name' => 'Cebu Hotel',
        'address' => 'Cebu Address',
        'hotel_title=> 'RESTAURANT',
        'hotel_description' => 'The Restaurant serving Western cuisines to cater your appetite and open for 24 hours'
    ),
);

我想组合具有相同值的数组。所以print_r的结果是这样的：

Array
(
    [id] => 1
    [hotel_code] => PHCEB_00001
    [hotel_name] => Cebu Hotel
    [address] => Cebu Address
    [description] => Array
        (
            [0] => Array
                (
                    [hotel_title] => LOCATION DETAIL
                    [hotel_description] => 7 kms to city centre 2 kms to the airport 60 kms to the airport 6 km to the nearest station
                )

            [1] => Array
                (
                    [hotel_title] => ROOMS
                    [hotel_description] => Rooms with elegant set up viewing our beautiful natural landscape garden, private balcony
                )

            [2] => Array
                (
                    [hotel_title] => RESTAURANT
                    [hotel_description] => The Restaurant serving Western cuisines to cater your appetite and open for 24 hours
                )

        )

)

我试图解决我的问题，但我仍然感到困惑

我只能制作这样的代码：

$tmp = array();

    foreach($arr as $arg)
    {

        $tmp['description'][]['hotel_description'] = $arg['hotel_description'];
    }

解决我问题的任何解决方案？

非常感谢

当有“酒店”以及随机顺序中不同的“ id ”字段时，我已经复杂了您的初始数组以显示复杂情况。
使用uasort，array_reduce和array_diff函数的解决方案：

$arr = array(
    array(
        'id' => 1,
        'hotel_code' => 'PHCEB_00001',
        'hotel_name' => 'Cebu Hotel',
        'address' => 'Cebu Address',
        'hotel_title' => 'LOCATION DETAIL',
        'hotel_description' => '7 kms to city centre 2 kms to the airport 60 kms to the airport 6 km to the nearest station ',
    ),
    array(
        'id' => 2,
        'hotel_code' => 'PHCEB_00001',
        'hotel_name' => 'Cebu Hotel',
        'address' => 'Cebu Address',
        'hotel_title' => 'test',
        'hotel_description' => 'Test'
    ),
    array(
        'id' => 1,
        'hotel_code' => 'PHCEB_00001',
        'hotel_name' => 'Cebu Hotel',
        'address' => 'Cebu Address',
        'hotel_title'=> 'RESTAURANT',
        'hotel_description' => 'The Restaurant serving Western cuisines to cater your appetite and open for 24 hours'
    ),
    array(
        'id' => 1,
        'hotel_code' => 'PHCEB_00001',
        'hotel_name' => 'Cebu Hotel',
        'address' => 'Cebu Address',
        'hotel_title' => 'ROOMS',
        'hotel_description' => 'Rooms with elegant set up viewing our beautiful natural landscape garden, private balcony'
    ),
);

uasort($arr, function($a,$b){

$result = [];

            'address' => $prev['address'],
            'description' => [

试试这个：它简单易用......

<?php 
$arr = array(
    array(
        'id' => 1,
        'hotel_code' => 'PHCEB_00001',
        'hotel_name' => 'Cebu Hotel',
        'address' => 'Cebu Address',
        'hotel_title' => 'LOCATION DETAIL',
        'hotel_description' => '7 kms to city centre 2 kms to the airport 60 kms to the airport 6 km to the nearest station ',
    ),
    array(
        'id' => 1,
        'hotel_code' => 'PHCEB_00001',
        'hotel_name' => 'Cebu Hotel',
        'address' => 'Cebu Address',
        'hotel_title' => 'ROOMS',
        'hotel_description' => 'Rooms with elegant set up viewing our beautiful natural landscape garden, private balcony'
    ),
    array(
        'id' => 1,
        'hotel_code' => 'PHCEB_00001',
        'hotel_name' => 'Cebu Hotel',
        'address' => 'Cebu Address',
        'hotel_title' => 'RESTAURANT',
        'hotel_description' => 'The Restaurant serving Western cuisines to cater your appetite and open for 24 hours'
    )
);

$intersect = array_intersect($arr[0], $arr[1], $arr[2]);
$intersectkeys = array_keys($intersect);

foreach ($arr as $key1 => $value1) {
    foreach ($value1 as $key2 => $value2) {
        if(in_array($key2, $intersectkeys)){            
            unset($arr[$key1][$key2]);
        }
    }
}
$newarr['description'] = $arr;
$result = array_merge($intersect, $newarr);
echo "<pre>".print_r($result,1)."</pre>";
?>

输出：

Array
(
    [id] => 1
    [hotel_code] => PHCEB_00001
    [hotel_name] => Cebu Hotel
    [address] => Cebu Address
    [description] => Array
        (
            [0] => Array
                (
                    [hotel_title] => LOCATION DETAIL
                    [hotel_description] => 7 kms to city centre 2 kms to the airport 60 kms to the airport 6 km to the nearest station 
                )

            [1] => Array
                (
                    [hotel_title] => ROOMS
                    [hotel_description] => Rooms with elegant set up viewing our beautiful natural landscape garden, private balcony
                )

            [2] => Array
                (
                    [hotel_title] => RESTAURANT
                    [hotel_description] => The Restaurant serving Western cuisines to cater your appetite and open for 24 hours
                )

        )

)
