How to merge array with same key into single array with all the key

Question

I want to merge array with the same name and show all the same name in a single array.

I have array show below

Array
(
    [0] => Array
        (
            [location_name] => NTPL Vault
        )

    [1] => Array
        (
            [location_name] => NTPL Safe Room
        )

    [2] => Array
        (
            [location_name] => Safe NTPL
        )

)




$array = call_user_func_array('array_merge', $myArray);

I am expecting output as below...

[
  {
    "location_name": "NTPL"
  },
  {
    "location_name": "NJKL"
  },
  {
    "location_name": "KLDF"
  }
]

@Zeljka actually not, look at the values. But how those values got transformed is anyone's guess — Andreas, Apr 24 '19 at 13:55
you are right @Andreas i didnt saw that values are different — Zeljka, Apr 24 '19 at 13:56
Your two examples are same kind of array but noted differently. One is the output of php's `var_dump` and one is in json. You need to explain more what you really want (to do). — user3190433, Apr 24 '19 at 14:13

Your desired output is in JSON format, for which there are two commonly used functions in PHP:

For changing arrays from PHP forms to JSON, you might use json_encode and vice versa:

$array = array
    (
    '0' => array
    (
        'location_name' => 'NTPL Vault',
    ),

    '1' => array
    (
        'location_name' => 'NTPL Safe Room',
    ),

    '2' => array
    (
        'location_name' => 'Safe NTPL',
    ),

);

$output = json_encode($array);
var_dump($output);

Output:

string(97) "[{"location_name":"NTPL Vault"},{"location_name":"NTPL Safe Room"},{"location_name":"Safe NTPL"}]"

If you wish to change the values of location_name, you might simply use other functions.
