用PHP制作三维关联数组

我想做的是基于MYSQL表中的列事件id创建多维关联数组

我想要的一个例子就是这个数组，php代码就是我目前所拥有的

[
'event_id #1' : [{id=24, name: "Joe", code: "dsf34fsf"},{id=25,name: "Bob", code: "nlwr32"],
'event_id #2' : [{id=54, name: "Kevin", code: "sdfs"},{id=57,name: "Dan"}, code: "i5er343"]
]

    //Get tickets for the event if the user bought them
$query = mysqli_query($db_conx, "SELECT id, name, event_id, code FROM tickets WHERE user_id='$user_id' ORDER BY event_id DESC");    

while ($row = mysqli_fetch_array($query, MYSQLI_ASSOC)) {
    $ticket_id = $row["id"];
    $code = $row["code"];
    $name = $row["name"];
    $event_id =  $row["event_id"];                        
    $tickets[] = array($event_id => array('id' => $ticket_id, 'n' => $name, 'c' => $code));
}

您只需更改：

$tickets[] = array($event_id => array('id' => $ticket_id, 'n' => $name, 'c' => $code));

致：

对于示例数据，这将给出如下结果：

Array
(
    [event_id #1] => Array
        (
            [0] => Array
                (
                    [id] => 24
                    [n] => Joe
                    [c] => dsf34fsf
                )    
            [1] => Array
                (
                    [id] => 25
                    [n] => Bob
                    [c] => nlwr32
                )    
        )    
    [event_id #2] => Array
        (
            [0] => Array
                (
                    [id] => 54
                    [n] => Kevin
                    [c] => sdfs
                )    
            [1] => Array
                (
                    [id] => 57
                    [n] => Dan
                    [c] => i5er343
                )    
        )    
)

在不知道你拥有什么的情况下，向我们展示你想要的是一点雄心壮志我编辑了这个问题。数组是我想要的，PHP代码是我在实现这一点上取得的进展。不用担心，很高兴我能提供帮助。

Array

    [event_id #1] => Array
        (
            [0] => Array
                (
                    [id] => 24
                    [n] => Joe
                    [c] => dsf34fsf
                )    
            [1] => Array
                (
                    [id] => 25
