php 我怎样才能有一个多维数组的周期

我正在创建一个计划，我想按时间范围分组，例如：月份号2（二月）已预订。这就是为什么不在$free_time_frame中

$free_time_frame = [];

$start = new DateTime("2022-01-01");
$end = new DateTime("2022-12-31");

$interval = new DateInterval("P1M"); // 1 month interval
$period = new DatePeriod($start, $interval, $end);
$seasons = [8,2];
foreach ($period as $date) {
    if (in_array($date->format("n"), $seasons)) {
        // Skip the rest of the loop if the current month is in the $seasons array
        continue;
    }

    // Set the start date to the first day of the month
    $start_date = new DateTime($date->format("Y-m-01"));
    // Set the end date to the last day of the month
    $end_date = new DateTime($date->format("Y-m-t"));

    // Calculate the number of days between the start and end dates
    $diff = $start_date->diff($end_date);
    $days = $diff->days + 1; // Add 1 to include the end date

    $free_time_frame[] = [
        "from" => $start_date->format("Y-m-d"),
        "to" => $end_date->format("Y-m-d"),
        "slot" => $days,
    ];
    $start->modify("+1 month");
}

这就是结果：

[{
    "from": "2022-01-01",
    "to": "2022-01-31",
    "frame": 31,
    "season": 1
}, {
    "from": "2022-03-01",
    "to": "2022-03-31",
    "frame": 31,
    "season": 3
}, {
    "from": "2022-04-01",
    "to": "2022-04-30",
    "frame": 30,
    "season": 4
}, {
    "from": "2022-05-01",
    "to": "2022-05-31",
    "frame": 31,
    "season": 5
}, {
    "from": "2022-06-01",
    "to": "2022-06-30",
    "frame": 30,
    "season": 6
}, {
    "from": "2022-07-01",
    "to": "2022-07-31",
    "frame": 31,
    "season": 7
}, {
    "from": "2022-09-01",
    "to": "2022-09-30",
    "frame": 30,
    "season": 9
}, {
    "from": "2022-10-01",
    "to": "2022-10-31",
    "frame": 31,
    "season": 10
}, {
    "from": "2022-11-01",
    "to": "2022-11-30",
    "frame": 30,
    "season": 11
}, {
    "from": "2022-12-01",
    "to": "2022-12-31",
    "frame": 31,
    "season": 12
}]

我想要完成的任务：
如您所见，我有一个平面数组，包含除二月以外的所有月份。我想将$season之前的月份放在一个数组中，将$season之后的月份放在另一个数组中，始终放在$free_time_frame内
预期结果：

[
   [
      {
         "from":"2022-01-01",
         "to":"2022-01-31",
         "frame":31,
         "season":1
      }
   ],
   [
      {
         "from":"2022-03-01",
         "to":"2022-03-31",
         "frame":31,
         "season":3
      },
      {
         "from":"2022-04-01",
         "to":"2022-04-30",
         "frame":30,
         "season":4
      },
      {
         "from":"2022-05-01",
         "to":"2022-05-31",
         "frame":31,
         "season":5
      },
      {
         "from":"2022-06-01",
         "to":"2022-06-30",
         "frame":30,
         "season":6
      },
      {
         "from":"2022-07-01",
         "to":"2022-07-31",
         "frame":31,
         "season":7
      }
     ],
     [
      {
         "from":"2022-09-01",
         "to":"2022-09-30",
         "frame":30,
         "season":9
      },
      {
         "from":"2022-10-01",
         "to":"2022-10-31",
         "frame":31,
         "season":10
      },
      {
         "from":"2022-11-01",
         "to":"2022-11-30",
         "frame":30,
         "season":11
      },
      {
         "from":"2022-12-01",
         "to":"2022-12-31",
         "frame":31,
         "season":12
      }
   ]
]

PHP不支持“多维数组”，你需要的是嵌套数组。
当赛季结束的时候添加空数组并使用它。用第一个嵌套数组初始化。

<?php declare(strict_types = 1);
$free_time_frame = [[]];  // nested array here

$start = new DateTime("2022-01-01");
$end = new DateTime("2022-12-31");

$interval = new DateInterval("P1M"); // 1 month interval
$period = new DatePeriod($start, $interval, $end);
$seasons = [8,2];
foreach ($period as $date) {
  if (in_array($date->format("n"), $seasons)) {
    // Skip the rest of the loop if the current month is in the $seasons array
    $free_time_frame[] = [];   // append nested array
    continue;
  }

  // Set the start date to the first day of the month
  $start_date = new DateTime($date->format("Y-m-01"));
  // Set the end date to the last day of the month
  $end_date = new DateTime($date->format("Y-m-t"));

  // Calculate the number of days between the start and end dates
  $diff = $start_date->diff($end_date);
  $days = $diff->days + 1; // Add 1 to include the end date

  // use the latest nested array
  $free_time_frame[array_key_last($free_time_frame)][] = [
    "from" => $start_date->format("Y-m-d"),
    "to" => $end_date->format("Y-m-d"),
    "slot" => $days,
  ];
  $start->modify("+1 month");
}

echo json_encode($free_time_frame, JSON_PRETTY_PRINT);

您可能希望扩展您的算法，以便在添加新的嵌套数组之前检查最新的嵌套数组是否为空，例如，当$seasons与[2,3,10]相似时。
