如何与QUOT;扁平化＆QUOT;多维数组简单的在PHP？ [英] How to "flatten" a multi-dimensional array to simple one in PHP?

问题描述

这也可能是初学者问题，但我会通过文档较长的时间已经和我找不到任何解决方案。我以为我可以使用破灭每个维度，然后把这些字符串后面加上 str_split 作出新​​的简单的数组。不过，我从来不知道，如果加盟模式不也是价值观和做经过了这么 str_split 我原来的值可能会断裂。

It's probably beginner question but I'm going through documentation for longer time already and I can't find any solution. I thought I could use implode for each dimension and then put those strings back together with str_split to make new simple array. However I never know if the join pattern isn't also in values and so after doing str_split my original values could break.

有什么样组合（$数组1，$数组2）的内部多维数组数组？

Is there something like combine($array1, $array2) for arrays inside of multi-dimensional array?

推荐答案

使用 array_values​​ 。 （从PHP网站为例）

Use array_values. (Example from php site)

<?php

$aNonFlat = array(
    1,
    2,
    array(
        3,
        4,
        5,
        array(
            6,
            7
        ),
        8,
        9,
    ),
    10,
    11
);

$objTmp = (object) array('aFlat' => array());

array_walk_recursive($aNonFlat, create_function('&$v, $k, &$t', '$t->aFlat[] = $v;'), $objTmp);

var_dump($objTmp->aFlat);

/*
array(11) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  int(3)
  [3]=>
  int(4)
  [4]=>
  int(5)
  [5]=>
  int(6)
  [6]=>
  int(7)
  [7]=>
  int(8)
  [8]=>
  int(9)
  [9]=>
  int(10)
  [10]=>
  int(11)
}
*/

?>
