PHP 分解多维数组

Question

我有多个数组，我正试图分解并划分其中的所有信息。出于某种原因，当我这样做时，我丢失了有关主数组的信息。

数组

[0] => Array (
    [0] => 2020-11-01 / 2020-11-30
    [1] => 2020-12-01 / 2020-12-31
    )
[1] => Array (
    [0] => 2020-11-01 / 2020-11-30
    [1] => 2020-12-01 / 2020-12-31
    )

我使用了以下代码：

foreach ($list as $line) {
    foreach ($line as $text) {
        $parts[] = explode(' / ', $text);
    }
}

print_r($parts) 将 return 以下内容：

[0] => Array (
    [0] => 2020-11-01
    [1] => 2020-11-30
    )
[1] => Array (
    [0] => 2020-12-01
    [1] => 2020-12-31
    )
[2] => Array (
    [0] => 2020-11-01
    [1] => 2020-11-30
    )
[3] => Array (
    [0] => 2020-12-01
    [1] => 2020-12-31
    )

但不幸的是，这不是我要找的，我需要的是：

[0] => Array (
    [0] => Array (
        [0] => 2020-11-01
        [1] => 2020-11-30
        )
    [1] => Array (
        [0] => 2020-12-01
        [1] => 2020-12-31
        )
    )
[1] => Array (
    [0] => Array (
        [0] => 2020-11-01
        [1] => 2020-11-30
        )
    [1] => Array (
        [0] => 2020-12-01
        [1] => 2020-12-31
        )
    )

我四处搜索，但没有找到一个简单的方法。希望有人能帮忙。谢谢！

如果您真的想保持原始阵列完好无损。一个解决方案是使用另一个数组将你的分解数组放在里面：

<?php

$list = [
  [
    "2020-11-01 / 2020-11-30",
    "2020-11-01 / 2020-11-30",
  ],
  [
    "2020-11-01 / 2020-11-30",
    "2020-11-01 / 2020-11-30",
  ]
];

$newArray = [];
foreach ($list as $line) {
  $parts = [];
  foreach ($line as $text) {
      $parts[] = explode(' / ', $text);
  }
  $newArray[] = $parts;
}
var_dump($newArray);

/*
array (size=2)
  0 => 
    array (size=2)
      0 => 
        array (size=2)
          0 => string '2020-11-01' (length=10)
          1 => string '2020-11-30' (length=10)
      1 => 
        array (size=2)
          0 => string '2020-11-01' (length=10)
          1 => string '2020-11-30' (length=10)
  1 => 
    array (size=2)
      0 => 
        array (size=2)
          0 => string '2020-11-01' (length=10)
          1 => string '2020-11-30' (length=10)
      1 => 
        array (size=2)
          0 => string '2020-11-01' (length=10)
          1 => string '2020-11-30' (length=10)
*/

您正在创建一个新数组，而不是写入您正在展开的相同索引，您可以这样做：

$arr = [
    0 => [
        0 => '2020-11-01 / 2020-11-30',
        1 => '2020-12-01 / 2020-12-31',
    ],
    1 => [
        0 => '2020-11-01 / 2020-11-30',
        1 => '2020-12-01 / 2020-12-31',
    ]
];


foreach ($arr as $bulkIndex => $bulks) {
    foreach ($bulks as $lineIndex => $line) {
        $arr[$bulkIndex][$lineIndex] = explode(' / ', $line);
    }
}

您可以通过嵌套 array_map 分解每个值中的数据来实现您想要的结果：

$data = array(
  array(
    "2020-11-01 / 2020-11-30",
    "2020-11-01 / 2020-11-30",
  ),
  array(
    "2020-11-01 / 2020-11-30",
    "2020-11-01 / 2020-11-30",
  )
);

$result = array_map(function ($a) { 
    return array_map(function ($v) { 
        return explode(' / ', $v ); 
    }, $a); 
}, $data);
print_r($result);
