如何在php中对多数组进行排序,php,arrays,Php,Arrays,我有一个多维数组，我想在每个数组嵌套数组中基于SequenceID排序数组，基于序列号，如1,2,3,4,5,6，如SequenceID数据显示。如何做到这一点请任何人在这方面的帮助。我的数组数据如下 <?php $dataarray= array( "CAR_DATA" => array( "SNo" => 1607, "SRRequestID" => 22666

我有一个多维数组，我想在每个数组嵌套数组中基于SequenceID排序数组，基于序列号，如1,2,3,4,5,6，如SequenceID数据显示。如何做到这一点请任何人在这方面的帮助。我的数组数据如下

<?php

$dataarray=  array(

            "CAR_DATA" => array(
                   "SNo" => 1607,
                   "SRRequestID" => 22666,
                   "AncillarySearchID"=>3333,
                   "car_data_line" => array (
                           "QuoteID" => 1607,
                           "SequenceID" => 5
                        ) 
                     ),
            "FLIGHT_DATA" => array(
                "SNo" => 1212,
                "SRRequestID" => 2222,
                "FLightSearchID"=>3333,
                "flight_data_line" => array (
                        "QuoteID" => 3222,
                        "SequenceID" => 2
               )
             ),

            "FLIGHT_DATA" => array(
                    "SNo" => 3222,
                    "SRRequestID" => 2222,
                    "FLightSearchID"=>3333,
                    "flight_data_line" => array (
                            "QuoteID" => 3222,
                            "SequenceID" => 1
                   )
                 ),


            "HOTEL_DATA" => array(
                    "SNo" => 343,
                    "SRRequestID" => 212,
                    "HotelSearchID"=>3434,
                    "hotel_data_line" => array (
                        "QuoteID" => 456,
                        "SequenceID" => 3
                   )
                 ),

            "HOTEL_DATA" => array(
                    "SNo" => 32,
                    "SRRequestID" => 3333,
                    "HotelSearchID"=>343,
                    "hotel_data_line" => array (
                        "QuoteID" => 121,
                        "SequenceID" => 6
                   )
                 ),

                 "HOTEL_DATA" => array(
                    "SNo" => 344,
                    "SRRequestID" => 34343,
                    "HotelSearchID"=>4433,
                    "hotel_data_line" => array (
                        "QuoteID" => 22222,
                        "SequenceID" => 4
                   )
                 ),

             );

        echo "<pre>";print_r($dataarray);
        ?>

假设您能够按照这种方式制作阵列。因为在数组中有重复的键。您不能保留密钥，因为PHP将保留最后一个密钥。因此，您的阵列应采用以下方式：

<?php

function sortArrayBySequenceID($array) {

    $new = [];

    foreach ($array as $key => $value) {

        if (isset($value['CAR_DATA']['car_data_line']['SequenceID'])) {
            $new[$value['CAR_DATA']['car_data_line']['SequenceID']] = $array[$key];
        } elseif (isset($value['FLIGHT_DATA']['flight_data_line']['SequenceID'])) {
            $new[$value['FLIGHT_DATA']['flight_data_line']['SequenceID']] = $array[$key];
        } elseif (isset($value['HOTEL_DATA']['hotel_data_line']['SequenceID'])) {
            $new[$value['HOTEL_DATA']['hotel_data_line']['SequenceID']] = $array[$key];
        }

    }

    // Sorts the newly made array based on key
    ksort($new);

    return $new;
}

print_r(sortArrayBySequenceID($dataArray));

我无法理解排序顺序，使用哪个索引值对数据进行排序，以及排序顺序是什么

asc

或

desc

？我的原始代码已在上面编辑，请在我的原始代码中使用SequenceID进行检查和搜索，基于序列号，如1,2,3,4,5..数据需要显示原始数据的问题是，您有多个项目具有相同的键（

FLIGHT_data

），因此这将不起作用。

print\r（$dataarray）仅显示3项数据，其他数据因您的数据被覆盖而丢失。@NigelRen您所说的完全正确，是的，我有多个具有相同键的项目，如航班数据
，酒店数据
，汽车数据
。这个问题的解决方案是什么。但我的经理强迫我在最后两天继续工作。我必须而且应该做任何其他的解决方案。你能改变你如何生成这个数组吗？谢谢它的工作，但我想从我的原始数据。你能在我的帖子里查一下我的原始数据吗？我想知道数据的结果。请在此方面提供帮助。您的原始数据可能是打印（$some_变量）

的结果。你能用这个片段显示数据吗？

foreach（$qq为原始数据）{foreach（$q为$q）{$array=json_decode（json_encode（$q），true）；echo”“；print_r（$array）；echo”“；}}

使用上述代码打印此数据。我得到下面的代码片段，请在我的问题中检查更新的原始输出原始数据输出JSON编码和解码后请检查此链接
