As i searched alot but didn't get perfect solution of merging array in one single array.
These arrays are Dynamic (may be increase in future- would 50+). So for that we have to use `count()` or `for` `loops` to fetch and then merge.

Here's my code which i'm trying to resolve over core level. Please anyone tell me how may receive all values in Single array.

```
Array(
[0] => Array
    (
        [0] => 123
        [1] => 108
        [2] => 58
        [3] => 23
    )

[1] => Array
    (
        [0] => 93
        [1] => 94
        [2] => 95
        [3] => 172
        [4] => 30
    )

[2] => Array
    (
        [0] => 109
        [1] => 81
        [2] => 79
        [3] => 155       )

)`

```

My expectation of result is: (which i'm unable to get)

```
 Array
(
    [0] => 123
    [1] => 108
    [2] => 58
    [3] => 23
    [4] => 93
    [5] => 94
    [6] => 95
    [7] => 172
    [8] => 30
    [9] => 109
    [10] => 81
    [11] => 79
    [12] => 155
)

```
