I have original array as given below

```
$orginal_arra = Array(
    [0] => 53_0.1,
    [1] => 53_0.3,
    [2] => 54_0.2,
    [3] => 54_0.1,    
    [4] => 54_0.1,
    [5] => 54_0.19,
    [6] => 56_0.19,
    [7] => 56_0.50
);

```

The above array can explode by "\_" separating

```
foreach($orginal_arra as $part) {
    if($part){
        $arr_parts = explode("_",$part);
        $arr1[] = $arr_parts[0];
        $arr2[] = $arr_parts[1];
    }
}

```

The $arr1 result after sperating

```
Array (
    [0] => 53,
    [1] => 53,
    [2] => 54,
    [3] => 54,
    [4] => 54,
    [5] => 54,
    [6] => 56,
    [7] => 56
)

```

The $arr2 result after sperating

```
Array (
    [0] => 0.1,
    [1] => 0.3,
    [2] => 0.2,
    [3] => 0.1,
    [4] => 0.1,
    [5] => 0.19,
    [6] => 0.19,
    [7] => 0.50
)

```

I want to return the array by combining $arr1 and $arr2 as like

```
$array = Array(
    [0] => 53_0.3,
    [1] => 54_0.19,
    [2] => 56_0.50
);

```

Is there any way to get the result like above using PHP Arrays.
