合并json编码的数组

Question

Lets say I have these arrays:

$array1 = [
  'test' => json_encode([
      'key1' => 'val1',
      'key2' => 'val2',
      'key3' => 'val3'
   ])
]

Now I have another array

$array2 = [
  'test' => json_encode([
      'key4' => 'val4'
   ])
]

After merge I want it to look like :

$array3 = [
  'test' => json_encode([
      'key1' => 'val1',
      'key2' => 'val2',
      'key3' => 'val3',
      'key4' => 'val4',
   ])
]

But when I do $result = array_merge($array1, $array2)

Then I get this:

$array3 = [
  'test' => json_encode([
      'key4' => 'val4'
   ])
]

Any suggestions how to fix this? I tried it with array_merge_recursive but that also does not give the right result.

Thanks.

I fixed this to by putting the test key in it's own variable. Then I merged them and json_encoded it.
