Question

我有一家商店的营业时间：

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"
  ]
]

在这种情况下，数组从1到6的键是星期几（星期一至星期六），为此我使用了一个简单的Enum类：

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

所以，我需要得到一个将营业时间和营业时间相近的日期进行分组的结果，如下所示：

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

我无法弄清楚如何按opens_at和closes_at进行分组，以获得我所显示的任何格式化结果。预先感谢！

这不是一个非常优雅的解决方案，但是它可以提示您如何自己解决问题：

<?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));

结果：

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" }
