I have two arrays :

```
Array 1
(
    [0] => 976504282322
    [1] => 976530000022
)

```

=====

```
Array 2
(
    [0]  => Array
        (
            [Mobile]  => 978504282398
            [Name]  => Mike 
        )
    [1] => Array
        (
            [Mobile]  => 976504282300
            [Name]  => Jhon
        )
) 

```

====

I want to merge them and the final result should be :

===

```
Array3
(
    [0] => Array
        (
            [Mobile]  => 978504282398
            [Name]  => Mike 
        )

    [1] => Array
        (
            [Mobile]  => 976504282300
            [Name]  => Jhon
        )

    [2] => Array
        (
            [Mobile]  => 976504282322

        )

   [3] => Array
        (
            [Mobile]  => 976504282322

        )

)

```

Note : performance is very important here because each array have over 200,000 item , so using for loop is not a good idea.

my code :

```
foreach ($Array1 as $mobile=> $value) {
    $Array2[]['Mobile']=$value;
}

```
