将项目从一个数组添加到另一个数组

Question

我有两个数组:

1)第一个数组:

array(

    [0] => array(
              [code] => code_1
              [value] => xxx
    [1] => array(
              [code] => code_2
              [value] => xxx     
    [2] => array(
              [code] => code_3
              [value] => xxx     

2)第二个数组:

array(

    [0] => array(
              [settingcode] => code_1
              [value] => xxx
    [1] => array(
              [settingcode] => code_2
              [value] => xxx     
    [2] => array(
              [settingcode] => code_3
              [value] => xxx
    [3] => array(
              [settingcode] => code_4
              [value] => xxx     
    [4] => array(
              [settingcode] => code_5
              [value] => xxx    

如何从array2向array1 添加两个缺少的项目(code_4和code_5)？

谢谢!

UPD.

对不起,我需要澄清一下这个问题.我需要结果数组看起来像:

array(

    [0] => array(
              [code] => code_1
              [value] => xxx
    [1] => array(
              [code] => code_2
              [value] => xxx     
    [2] => array(
              [code] => code_3
              [value] => xxx
    [3] => array(
              [code] => code_4
              [value] => xxx     
    [4] => array(
              [code] => code_5
              [value] => xxx
