Question

我正在研究旅游网站项目我想要比较两个数组，但是当我尝试在数组中添加新东西时，过滤停止。我想过滤，如果两个房间相等，那么检查它的计划并显示房间有最低费率和其他剩余结果。我在下面写了代码

     $arr1  =   array(
    array (
                  'ratePlanCode'  => '1',
                'roomId'  => '10',
                'whotel' =>'0',
                'roomName' => 'Standard',
                'ratePlan' => 'CPAI',
                'roomRate' => 11000
            ),
      array
            (
                'ratePlanCode'  => '2',
                'roomId'  => '10',
                'whotel' =>'0',
                'roomName' => 'test',
                'ratePlan' => 'MAP',
                'roomRate' => 10000
            ),
    array
            (
                'ratePlanCode'  => '3',
                'roomId'  => '10',
                'whotel' =>'0',
                'roomName' => 'test123',
                'ratePlan' => 'CP',
                'roomRate' => 10000
            ),
    array
            (
                'ratePlanCode'  => '4',
                'roomId'  => '10',
                'whotel' =>'0',
                'roomName' => 'test',
                'ratePlan' => 'MAP',
                'roomRate' => 10000
            )        

        );


$arr2  =   array(
    array (
                'ratePlanCode'  => '10',
                'roomId'  => '10',
                'whotel' =>'1',
                'roomName' => 'Standard',
                'ratePlan' => 'CPAI',
                'roomRate' => 12000
            ),
      array
            (
                'ratePlanCode'  => '100',
                'roomId'  => '10',
                'whotel' =>'1',
                'roomName' => 'Honeymoon',
                'ratePlan' => 'MAP',
                'roomRate' => 10800
            ),

            array
            (
                'ratePlanCode'  => '102',
                'roomId'  => '10',
                'whotel' =>'1',
                'roomName' => 'test123',
                'ratePlan' => 'CP',
                'roomRate' => 9000
            ),
            array
            (
                'ratePlanCode'  => '101',
                'roomId'  => '10',
                'whotel' =>'1',
                'roomName' => 'waff',
                'ratePlan' => 'MAP',
                'roomRate' => 10800
            ));



//print_r($hotelArray);
$data123 = array_merge($arr1,$arr2);
//print_r($data);
$output = array();
foreach($data123 as $arr){
$output [$arr['roomName']][$arr['ratePlan']][$arr['ratePlanCode']][$arr['roomId']][] =$arr['roomRate'] ;
sort($output[$arr['roomName']][$arr['ratePlan']][$arr['ratePlanCode']][$arr['roomId']]);
}
print_R($output);
//deassemble
$data = array();

foreach($output as $roomName=>$arr1)
{
    foreach($arr1 as $ratePlan=>$arr2)
    {
            foreach($arr2 as $hotelId=>$arr3)
            {
                foreach($arr3 as $roomId=>$arr4)
                {
                    foreach($arr3 as $roomId=>$arr4)
                    {

                        $data[] = array(    
                        'ratePlanCode' => $hotelId,  
                        'roomId' => $roomId, 
                        'roomName' => $roomName,
                        'ratePlan' => $ratePlan,
                        'roomRate' => $arr4[0]);
                    }
                }
            }
    }
}
echo "Final Output";
print_R($data);

我正在获得这样的输出

[0] => Array
        (
            [ratePlanCode] => 1
            [roomId] => 10

            [ratePlan] => MAP
            [roomRate] => 10800
        )

但我希望得到如下的输出你能帮我解决这个问题吗

[0] => Array
        (
            [hotelId] => 10
            [roomId] => 10
            [roomName] => Standard
            [ratePlan] => CPAI
            [roomRate] => 11000
        )

    [1] => Array
        (
            [hotelId] => 10
            [roomId] => 10
            [roomName] => test
            [ratePlan] => MAP
            [roomRate] => 10000
        )

    [2] => Array
        (
            [hotelId] => 10
            [roomId] => 10
            [roomName] => test123
            [ratePlan] => CP
            [roomRate] => 9000
        )

    [3] => Array
        (
            [hotelId] => 10
            [roomId] => 10
            [roomName] => Honeymoon
            [ratePlan] => MAP
            [roomRate] => 10800
        )

正如我已经搜索但它不起作用

Answer 1

函数array_multisort（）非常有用，

   <?php
    $array = array('Alpha', 'atomic', 'Beta', 'bank');
    $array_lowercase = array_map('strtolower', $array);

    array_multisort($array_lowercase, SORT_ASC, SORT_STRING, $array);

    print_r($array);
    ?>

Answer 2

这是你的答案：）

$mergedArr = array_merge($arr1,$arr2);
$res = [];
foreach($mergedArr as $key=>$val){      
        $res[$val['roomRate']] = $val['roomName'];  
}
//echo '<pre>'; print_R($res);
ksort($res);
$res = array_unique($res);
//echo '<pre>'; print_R($res);
//echo '<pre>'; print_R();
$resultArrFinal = [];
foreach($mergedArr as $key=>$val){
    foreach($res as $k=>$v){
        if(in_array($k,$val) && in_array($v,$val)){
            $resultArrFinal[] = $val;       
        }
    }
 //echo $val['roomRate'].'   '.$val['roomName'];
}

echo '<pre>'; print_R($resultArrFinal);

如果你想要完全独特的记录，那么也在最后添加这一行。

function super_unique($array,$key)
{
   $temp_array = array();
   foreach ($array as &$v) {
       if (!isset($temp_array[$v[$key]]))
       $temp_array[$v[$key]] =& $v;
   }
   $array = array_values($temp_array);
   return $array;
}

echo '<pre>'; print_R(super_unique($resultArrFinal,'roomName'));

希望它会对你有所帮助:)。
