Php 如何从多维数组中删除特定键 这就是我需要得出的结果

但我得到的结果如下

下面是我所做的代码，我使用php mysql一对多关系将所有数据转换为平面数组，然后下面的代码将单个平面数组转换为三维数组，但我遇到了一个瓶颈。请帮助检查我的代码，指出我需要更改哪些部分才能成为我的预期结果

  $result = array();
    foreach($total_count as $Key => $Value){
        $ticketCatId = $Value['ticket_category_id'];
        $ticketId = $Value['ticket_id'];
        $ticketColorCode = $Value['ticket_color_code'];
        $ticketMember = $Value['user_id'];
    
        $result[$ticketCatId]['ticket_category_id'] = $Value['ticket_category_id'];
        $result[$ticketCatId]['ticket_category_name'] = $Value['ticket_category_name'];
        $result[$ticketCatId]['ticket_category_order']  = $Value['ticket_category_order'];

        if(!isset($result[$ticketCatId]['tickets'])) {
            $result[$ticketCatId]['tickets'] = array();
        }

        // this code is append the ticket ID
        if($ticketId && !isset($result[$ticketCatId]['tickets'][$ticketId])) {
            $ticket = array(

我没有任何样本数据可供使用，因此我无法为您实际测试。不过，一般的想法是，每次通过循环时，您都会初始化一个临时数组（

$tmpArray=array（）；

），并将所有特定于循环的值放入该数组中。然后，在每次循环迭代结束时，将该临时数组推送到

$results

数组（

$result[]=$tmpArray；

），允许PHP自动为

$results

创建顺序索引。当前获取嵌套JSON对象的原因是

JSON\u encode（）

将仅从顺序索引PHP数组生成JSON数组

  $result = array();
    foreach($total_count as $Key => $Value){
        $ticketCatId = $Value['ticket_category_id'];
        $ticketId = $Value['ticket_id'];
        $ticketColorCode = $Value['ticket_color_code'];
        $ticketMember = $Value['user_id'];

        $tmpArray = array();

        $tmpArray['ticket_category_id'] = $Value['ticket_category_id'];
        $tmpArray['ticket_category_name'] = $Value['ticket_category_name'];
        $tmpArray['ticket_category_order']  = $Value['ticket_category_order'];

        if(!isset($tmpArray['tickets'])) {
            $tmpArray['tickets'] = array();
        }

        // this code is append the ticket ID
        if($ticketId && !isset($tmpArray['tickets'][$ticketId])) {
            $ticket = array(
                'ticket_id'                         => $Value['ticket_id'],
                'ticket_title'                      => $Value['ticket_title'],
                'ticket_order'                      => $Value['ticket_order'],
                'due_date'                          => $Value['due_date'],
                'created_date'                      => $Value['created_date'],
                'edited_date'                       => $Value['edited_date'],
                'updated_date'                      => $Value['updated_date'],
                'is_complete'                       => $Value['is_complete'],
                'total_comment'                     => $Value['total_comment'],
                'total_attachment'                  => $Value['total_attachment'],
                'total_checklist_items'             => $Value['total_checklist_items'],
                'total_completed_checklist_items'   => $Value['total_completed_checklist_items'],
                'label' => array(),
                'people' => array()

            );
            $tmpArray['tickets'][$ticketId] = $ticket;
        }

        if($ticketColorCode && isset($tmpArray['tickets'][$ticketId]) && !isset($tmpArray['tickets'][$ticketId]['label'][$ticketColorCode])) {
            $ticketColor = array(
                'ticket_label_name' => $Value['ticket_label_name'],
                'ticket_color_code' => $Value['ticket_color_code']
            );
            $tmpArray['tickets'][$ticketId]['label'][$ticketColorCode] = $ticketColor;
        }

        if($ticketMember && isset($tmpArray['tickets'][$ticketId]) && !isset($tmpArray['tickets'][$ticketId]['people'][$ticketMember])) {
            $ticketPeople = array(
                'user_id' => $Value['user_id'],
                'photo' => $Value['photo']
            );
            $tmpArray['tickets'][$ticketId]['people'][$ticketMember] = $ticketPeople;
        }

        $result[] = $tmpArray;
}

    dd(json_encode(["data"=>$result]));

允许PHP自动生成索引，而不是基于

$ticketCatId

的值指定

$result

的索引。聚合所有要添加到临时数组中的数据，然后只需执行

$result[]=$tmpArray

Hi@PatrickQ我是php数组的新手，你能给我上面描述的示例代码吗？谢谢。我已经测试了代码，它不是我想要的结果。应用代码后，按ticketid分组&ticket\u category\u id尚未工作。我无法理解您的意思。你能更新你的问题以显示新的结果吗？我已经更新了上面的结果，请看一看，票证类别id应该只出现一次，但现在正在重复，与票证id相同。等等，在

$total\u count

中是否有多行具有相同的

票证类别id

，您希望所有这些行通过

ticket\u category\u id

？@JASONWONG8合并。此外，您所说需要获取的示例不是有效的JSON。你在第一张票的第二个彩色条目上有一把钥匙（

“"D4891C:{

），那不可能在那里。
