How to combine array that has same key?

Question

I get this array, but I want to show me KEY and all subitem of that KEY bellow, I dont want every time to repear a key, I need that key shows only one and all others entity that has same key under this one.

 array(2) {
      [0]=>
      array(1) {
        ["A"]=>
        string(2) "Test1"
      }
      [1]=>
      array(1) {
        ["A"]=>
        string(2) "Test1"
      }
    }

I want something like this:

 array(2) {
      [0]=>
      array(1) {
        ["A"]=>
       string(2) "Test1", 
        string(2) "Test2"
      }
     }

Answer 1

use the following:

$return = array_merge_recursive($array, ...);

in your case:

$return = array_merge_recursive($array[0], $array[1]);

but I am guessing you'll want a more dynamic solution, I will draft that up now.

$return = call_user_func_array('array_merge_recursive', $array);
