php - 如何合并两个数组？

Question

我有两个这样的数组

第一个数组

Array
(
    [0228] => Array
        (
            [name] => ''
            [address] => ''
        )

    [0275] => Array
        (
            [name] => ''
            [address] => ''
        )
)

第二个数组

Array
(
    [0228] => Array
        (
            [start_date] => ''
            [payment] => ''
        )

    [0275] => Array
        (
            [start_date] => ''
            [payment] => ''
        )
)

我想通过匹配数组键来组合这两个，然后像这样输出

Array
(
    [0228] => Array
        (
            [name] => ''
            [address] => ''
            [start_date] => ''
            [payment] => ''
        )

    [0275] => Array
        (
            [name] => ''
            [address] => ''
            [start_date] => ''
            [payment] => ''
        )
)

如何做到这一点？ php 中是否有针对此类数组组合的内置函数？

问候

Answer 1

尝试

array_merge_recursive($array1, $array2);

这里还有更多的数组函数:http://www.php.net/manual/en/ref.array.php
