Laravel集合按兩列分組

Question

我有一間商店的營業時間：

array:3 [▼
  1 => array:2 [▼
    "opens_at" => "10:00"
    "closes_at" => "18:00"
  ]
  2 => array:2 [▼
    "opens_at" => "10:00"
    "closes_at" => "18:00"
  ]
  3 => array:2 [▼
    "opens_at" => "10:00"
    "closes_at" => "18:00"
  ]
  4 => array:2 [▼
    "opens_at" => "14:00"
    "closes_at" => "17:00"
  ]
  5 => array:2 [▼
    "opens_at" => "14:00"
    "closes_at" => "17:00"
  ]
  6 => array:2 [▼
    "opens_at" => "18:00"
    "closes_at" => "19:00"
  ]
]

在這種情況下，數組從1到6的鍵是星期幾（星期一至星期六），為此，我使用了一個簡單的Enum類：

class WeekDays
{
    const MONDAY = 1;
    const TUESDAY = 2;
    const WEDNESDAY = 3;
    const THURSDAY = 4;
    const FRIDAY = 5;
    const SATURDAY = 6;
    const SUNDAY = 7;
}

因此，我需要得到一個將營業時間和營業時間相近的日期進行分組的結果，如下所示：

[
    Mo,Tu,We 10:00-18:00,
    Th,Fr 14:00-17:00
    Sa 18:00-19:00
]

我無法弄清楚如何按opens_at和closes_at以獲取顯示的任何格式化結果。 提前致謝！

這不是一個非常優雅的解決方案，但是它可以提示您如何自己解決問題：

<?php

$a = [
  1 => [
    "opens_at" => "10:00",
    "closes_at" => "18:00"
  ],
  2 => [
    "opens_at" => "10:00",
    "closes_at" => "18:00"
  ],
  3 => [
    "opens_at" => "10:00",
    "closes_at" => "18:00"
  ],
  4 => [
    "opens_at" => "14:00",
    "closes_at" => "17:00"
  ],
  5 => [
    "opens_at" => "14:00",
    "closes_at" => "17:00"
  ],
  6 => [
    "opens_at" => "18:00",
    "closes_at" => "19:00"
  ]
];

$groups = [];

foreach($a as $dayNumber => $w){
    if(!array_key_exists($w['opens_at'] . '-' . $w['closes_at'], $groups)){
        $groups[$w['opens_at'] . '-' . $w['closes_at']] = [];
    }

    $groups[$w['opens_at'] . '-' . $w['closes_at']][] = $dayNumber;
}

$res = array_map(function($v){
    return implode(', ', $v);
}, $groups);

var_dump(array_flip($res));

結果是：

array(3) { ["1, 2, 3"]=> string(11) "10:00-18:00" ["4, 5"]=> string(11) "14:00-17:00" [6]=> string(11) "18:00-19:00" }
