将列数据的多维数组重组为行数据的多维数组

问题描述

我具有以下列数据的关联数组:

I have the following associative array of column data:

$where = array(
    'id'=>array(
        12,
        13,
        14
    ),
    'date'=>array(
        '1999-06-12',
        '2000-03-21',
        '2006-09-31'
    )
);

我需要将结构转置/旋转为一个行数组(将合并的列数据分配给它们各自的行).我不需要结果中的列名.

I need to transpose / rotate the structure to be an array of rows (with merged column data assigned to their respective row). I don't need the column names in the result.

预期输出:

$comb = array(
    array(12, '1999-06-12'),
    array(13, '2000-03-21'),
    array(14, '2006-09-31')
);

推荐答案

正如Kris Roofe在删除的答案中所述，array_column确实是一种更为优雅的方法.只要确保将其放入某种foreach循环中即可，就像Sahil Gulati向您展示的那样.例如，像这样:

As Kris Roofe stated in his deleted answer, array_column is indeed a more elegant way. Just be sure to put it into some kind of a foreach loop, similar to what Sahil Gulati showed you. For example, like this:

$result = array();

foreach($where['id'] as $k => $v)
{
  $result[] = array_column($where, $k);
}

$result的var_dump输出正是您要寻找的

The var_dump output of $result is exactly what you're looking for

array(3) {
  [0]=>
  array(2) {
    [0]=>
    int(12)
    [1]=>
    string(10) "1999-06-12"
  }
  [1]=>
  array(2) {
    [0]=>
    int(13)
    [1]=>
    string(10) "2000-03-21"
  }
  [2]=>
  array(2) {
    [0]=>
    int(14)
    [1]=>
    string(10) "2006-09-31"
  }
}
