Question

如果用户进行预订，则会生成与自行车类型一样多的新数据。数据库垂直增长。在进行预订时，它会产生一个唯一的密钥，并且在那一刻它是恒定的。例如：新的预订。＆＃39; Random0124＆＃39;和type_1：2数量，type_2：2数量。这意味着type_1 + type_2次存储在数据库中的新行。除自行车类型外，所有数据均相同。

＆＃39; bicycle_type＆＃39; =＆GT; 1个关系数据。这不是数量，这意味着type_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。

我想要结合所有内容，因为除了bicycle_type之外，所有数据都是相同的。

我有一个这样的数组：

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"
  ]
]

我如何组织这样的集合：

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,
                "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",

            ],
            2 => [

                "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",

            ],
        ];

        $result = [];

        foreach ( $as as $a ) {
        $reservationNumber = $a['reservation_number'];
        // Check if reservation number is exists in the result array or not.
        if ( ! isset($result[$reservationNumber]) ) {
            // If its not available we assign the current array to result.
            $result[$reservationNumber] = $a;
            $result[$reservationNumber]['bicycle_type'] = [];
        }

        // We check if bicycle_type is exists in the result having reservationNumber.
        // If its available we increment the value, otherwise initialize it with 1;
        if (isset($result[$reservationNumber]['bicycle_type'][$a['bicycle_type']])) {
            $result[$reservationNumber]['bicycle_type'][$a['bicycle_type']]['total'] += 1;
        } else {
            $result[$reservationNumber]['bicycle_type'][$a['bicycle_type']]['total'] = 1;
        }

    }

echo "<pre>";
        print_r($result);
echo "</pre>";
?>

如何分组相同的值？
