Merging two associative arrays in PHP

Question

I have been trying to merge two associative arrays all day. But I don't know whether it is possible or not in PHP.

first array

  'images' => 
      0 => 
          'image_first' => string 'http://10.0.2.2/captcha-2/iphone.png'
      1 => 
          'image_first' => string 'http://10.0.2.2/captcha-2/1425328_405486846250283_806381377_o.jpg'
      2 => 
          'image_first' => string 'http://10.0.2.2/captcha-2/bbg.jpg'
      3 => 
          'image_first' => string 'http://10.0.2.2/captcha-2/gmail_bg.JPG'

second array

'images' => 
      0 => 
          'image_second' => string 'http://10.0.2.2/captcha-2/Capture.JPG'
      1 => 
          'image_second' => string 'http://10.0.2.2/captcha-2/bg.jpg'
      2 => 
          'image_second' => string 'http://10.0.2.2/captcha-2/abc.JPG'
      3 => 
          'image_second' => string 'http://10.0.2.2/captcha-2/bg_dark.png'
      4 => 
          'image_second' => string 'http://10.0.2.2/captcha-2/bktile.png'

And they should be merged together like this.

merged array

  'images' => 
      0 => 
          'image_first' => string 'http://10.0.2.2/captcha-2/iphone.png'
      1 => 
          'image_first' => string 'http://10.0.2.2/captcha-2/1425328_405486846250283_806381377_o.jpg'
      2 => 
          'image_first' => string 'http://10.0.2.2/captcha-2/bbg.jpg'
      3 => 
          'image_first' => string 'http://10.0.2.2/captcha-2/gmail_bg.JPG'
      4 => 
          'image_second' => string 'http://10.0.2.2/captcha-2/Capture.JPG'
      5 => 
          'image_second' => string 'http://10.0.2.2/captcha-2/bg.jpg'
      6 => 
          'image_second' => string 'http://10.0.2.2/captcha-2/abc.JPG'
      7 => 
          'image_second' => string 'http://10.0.2.2/captcha-2/bg_dark.png'
      8 => 
          'image_second' => string 'http://10.0.2.2/captcha-2/bktile.png'

How to do it?

[array_merge](http://de2.php.net/manual/en/function.array-merge.php) - Did you even consult the docs? — ccKep, May 13 '14 at 16:49
Do you want other result than array_merge? If so you should give output you expect not only what was your result — Marcin Nabiałek, May 13 '14 at 16:50

this is not a simple array mergin, this is an array inside another array — Hybrid Developer, May 13 '14 at 16:51
array_merge() will replace existing keys. See my answer below. — Fydo, May 13 '14 at 16:57

-1 because: from the docs 'If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. 'see @Fydo's answer – toesslab May 13 '14 at 17:00
@pc-shooter Literally the next sentence in the documentation: "If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended." – Alexis King May 13 '14 at 17:04
@pc-shooter -1 your comment, because when the array has numeric keys, they are not replaced. See @ php documentation's answer. – Chris Baker May 13 '14 at 17:04
