Question

我有两个数组，我需要将它们组合成一个数组。我尝试了array_merge，array_combine，但它无效。有人能帮助我吗？

First Array

Array
(

[6] => Array
    (
        [nid] => 5
        [title] => YSL
        [field_category] => test
        [field_collection_creation] => 
        [body] => 
    )

)

第二个数组

Array
(

[0] => Array
    (
        [nid] => 13
        [title] => ar
        [field_category] => test
        [field_collection_creation] => 
        [body] => 
    )

[1] => Array
    (
        [nid] => 14
        [title] => bi
        [field_category] => test
        [field_collection_creation] => 
        [body] => 
    )

[2] => Array
    (
        [nid] => 28
        [title] => lc
        [field_category] => test
        [field_collection_creation] => 
        [body] => 
    )

[3] => Array
    (
        [nid] => 21
        [title] => gat
        [field_category] => test
        [field_collection_creation] => 
        [body] => 
    )

[4] => Array
    (
        [nid] => 20
        [title] => testle
        [field_category] => test
        [field_collection_creation] => 
        [body] => 
    )

[5] => Array
    (
        [nid] => 29
        [title] => test
        [field_category] => test
        [field_collection_creation] => 
        [body] => 
    )

)

我如何组合这两个数组，保持它们的键是什么？

Answer 1

因为 Index不会出现在两个数组中使用通常的foreach

foreach($ar1 as $k=>$v)
  $ar2[$k] = $v;

它从一个数组获取键和值，并在其他数组中创建相同的键值对

Answer 2

只需使用数组union +运算符合并数组：

//  $first and $second - are your arrays respectively
$result = $second + $first;  // $result contains the combined array

如果要将第二个数组中的数组元素追加到第一个数组，而不是覆盖第一个数组中的元素而不是重新索引，使用 + 数组联合运算符：

梳理两个数组PHP
