Php 如何对相同的值进行分组？

如果用户进行预订，将生成与自行车类型相同的新数据。数据库垂直增长。当进行预订时，它会生成一个唯一的密钥，并且在该时刻保持不变。例如： 作出了新的保留。”随机数0124'和类型_1:2数量，类型_2:2数量。这意味着type_1+type_2乘以数据库中存储的新行数。除自行车类型外，所有数据均相同

“bicycle_type”=>1个关系数据。这不是数量，这意味着类型1或类似的东西

基本上我想用预订号码分组。我想返回属于该预订号码的自行车类型和总数

我想合并所有数据，因为除了bicycle\u类型之外，所有数据都是相同的

我有这样一个数组：

array:3 [▼
  0 => array:12 [▼
    "id" => 13
    "reservation_number" => "58f382bfc4e52"
    "bicycle_type" => 1
    "start_date" => "2017-04-23 12:00:00"
    "stop_date" => "2017-04-23 13:00:00"
    "identity_number" => "11111111110"
    "name_lastname" => "John Doe"
    "email" => "John@doe.com"
    "phone" => "(124) 124 12 41"
    "is_complete" => 1
    "created_at" => "2017-04-16 17:42:21"
    "updated_at" => "2017-04-16 17:42:21"
  ]
  1 => array:12 [▼
    "id" => 14
    "reservation_number" => "58f382bfc4e52"
    "bicycle_type" => 1
    "start_date" => "2017-04-23 12:00:00"
    "stop_date" => "2017-04-23 13:00:00"
    "identity_number" => "11111111110"
    "name_lastname" => "John Doe"
    "email" => "John@doe.com"
    "phone" => "(124) 124 12 41"
    "is_complete" => 1
    "created_at" => "2017-04-16 17:42:21"
    "updated_at" => "2017-04-16 17:42:21"
  ]
  2 => array:12 [▼
    "id" => 15
    "reservation_number" => "58f382bfc4e52"
    "bicycle_type" => 2
    "start_date" => "2017-04-23 12:00:00"
    "stop_date" => "2017-04-23 13:00:00"
    "identity_number" => "11111111110"
    "name_lastname" => "John Doe"
    "email" => "John@doe.com"
    "phone" => "(124) 124 12 41"
    "is_complete" => 1
    "created_at" => "2017-04-16 17:42:21"
    "updated_at" => "2017-04-16 17:42:21"
  ]
]

我如何像这样组织此集合：

array:1 [▼
  '58f382bfc4e52' => array:12 [▼
    "id" => 13
    "reservation_number" => "58f382bfc4e52"
    "bicycle_types" => [
        '1' => [
            'total' => 2,
        ],
        '2' => [
            'total' => 1
        ]
    ]  
    "start_date" => "2017-04-23 12:00:00"
    "stop_date" => "2017-04-23 13:00:00"
    "identity_number" => "11111111110"
    "name_lastname" => "John Doe"
    "email" => "John@doe.com"
    "phone" => "(124) 124 12 41"
    "is_complete" => 1
    "created_at" => "2017-04-16 17:42:21"
    "updated_at" => "2017-04-16 17:42:21"
  ]
]

检查循环：

<?php

$as = [
            0 => [
                "id"                 => 13,

                "bicycle_type"       => 1,
                "start_date"         => "2017-04-23 12:00:00",
                "stop_date"          => "2017-04-23 13:00:00",
                "identity_number"    => "11111111110",
                "name_lastname"      => "John Doe",

我认为您的问题不够清楚。我组织了内容。请解释为什么这会有助于解决问题。虽然看起来您的代码应该可以工作，但在大多数情况下，只是闪出一些代码是不行的helpful@giorgio我理解你的担心。但是guy请求帮助生成生成给定结果的代码。没有什么可以解释的。但正如在编程中所说的，您必须对代码进行注释，以便每个人都能理解它。我在循环中添加了注释。总有一些事情需要解释，特别是当有人请求帮助时，这表明他或她不了解某些事情是如何工作的。我添加了关于我正在尝试做什么的细节。我不知道如何使这成为可能。
