I have an array `$result_array`, i am trying to push multi dimentional values into this array
without specifying the index as like below

```
$result_array[]["name"] = "Balan"
$result_array[]["active"] = true

```

But the resultant array looks like

```
Array
(
 [0] => Array
  (
   "name" => Balan
  )
 [1] => Array
  (
   "active" => true
  )
)

```

But the result i would like to have is like below

```
Array
(
 [0] => Array
  (
   "name" => Balan
   "active" => true
  )
)

```

Please note, i am aware i can initialize a `$key = 0` and increment it on each loop to
achieve this. But i would like to know how i can do this without using a separate variable and increment it.

Thanks.
