如何使用PHP中的日期重新排列/重组数组？

Question

我有一个日期在2017年10月10日至11日之间的数组。这些项目按时间顺序列出。

我正在寻找一个PHP解决方案来重新排列数组的结构或智能循环，以便我可以按照自己喜欢的方式组织日期。

我需要回应的是： （旧尝试，请忽略此示例。只需将其保留在已提供的解决方案中。请参阅下面的更新。）

'1', '1, 10, 2017', '1, 11, 2017'
'2', '2, 10, 2017', '2, 11, 2017',
...
'30', '30, 10, 2017', '30, 11, 2017',
'31', '31, 10, 2017', ''

请注意，11月（11）只有30天，因此没有第31个条目。

所以我需要一个遍历数组的循环，并在相同的开始日回应所有日期，然后做一个<br>或类似的。它总是应该在31号结束时有数据与否。

---

更新： 我的输出需要略有不同：

['1', '1, 10, 2017', '1, 11, 2017'],
['2', '2, 10, 2017', '2, 11, 2017'],
...
['30', '30, 10, 2017', '30, 11, 2017'],
['31', '31, 10, 2017', '0, 0, 0']

主要变化是：

• 方括号
• 如果没有值（例如，11月31日不存在），我需要像以前一样输出'0, 0, 0'而不是空字符串。

背景是我有一个必然需要任何值的函数，可能是0。

---

我尝试了不同的东西（将日期，月份和年份分开来分离数组/使用for-loops /使用foreach-loops）但没有真正起作用。我的主要问题似乎是每个月都有不同的天数。

你有什么建议如何工作？尝试重组阵列可能会更好吗？还是有其他解决方案？

代码应该使用不同的日期范围（不仅是我上面提到的那些）。

这是我的阵列：

    Array
(
    [0] => 1, 10, 2017
    [1] => 2, 10, 2017
    [2] => 3, 10, 2017

感谢您的任何帮助！

看来你想要的结果是一种伪数组字符串。如果您打算将其用作数组或json，我可以优化此代码以更好地满足您的最终要求。

代码展示了3个不同的起点：（qa​​zxswpoi）

并且根据经验：如果您发现自己手动定义了大量重复的数组，那么您应该退后一步并重新检查您的方法。

Answer 3

我完全同意@Sammitch对此的看法。如果必须使用此数组，则可以遍历数组并使用strtotime在Unix时间内转换条目：

http://php.net/manual/en/book.datetime.php

如果你想按原样处理数组，这里有一些东西可以让你接近你想要的东西：

foreach($date_array as $key => $value) {
  $value = explode(",",$value);
  $value = trim($value[2])."-".trim($value[1])."-".trim($value[0]);
  $value = strtotime($value);
  $date_array[$key] = $value;
}

输出：

'1', '1, 10, 2017', '1, 11, 2017',
