PHP - 将一个数组添加到另一个数组(递归？)

Question

我有两个数组:

$array1 = array(
  'currencies' => array(
    'dollars' => array(80,120,75),
    'euro' => array(25,35,10,85),
  ),
);

$array2 = array(
  'currencies' => array(
    'dollars' => array(25),
  ),
);

我希望结果如下:

$result = array(
  'currencies' => array(
    'dollars' => array(80,120,75,25),
    'euro' => array(25,35,10,85),
  ),
);

这可以巧妙地完成吗？我试过了array_merge,array_merge_recursively等.

Answer 1

你是如何尝试使用array_merge_recursive的？因为这对我有用:

<?php
$array1 = array(
  'currencies' => array(
    'dollars' => array(80,120,75),
    'euro' => array(25,35,10,85),
  ),
);

$array2 = array(
  'currencies' => array(
    'dollars' => array(25),
  ),
);

var_dump(array_merge_recursive($array1, $array2));
