Your Input Array:

...
0{
    data{
        nid => 1
        vid => 1
        type => article
        field_new{
            und{
                0{
                    value => 11111
                }
            }
        }
    }
}
1{
    data{
        nid => 2
        vid => 2
        type => article
        field_new{
            und{
                0{
                    value => 33333
                }
            }
        }
    }
}

Your desired array:

...
0{
    data{
        nid => 1
        vid => 1
        type => article
        value => 11111
    }
}
1{
    data{
        nid => 2
        vid => 2
        type => article
        value => 33333
    }
}

Unset (http://php.net/manual/en/function.unset.php) is our friend.

unset() destroys the specified variables.

Use this code:

<?php

$loop_count = count($input_arr);
for($i=0;$i<loop_count;$i++){
    //copy the value to the desired place
    $input_arr[$i]["data"]["value"] = $input_arr[$i]["data"]["field_new"]["und"][0]["value"];

    //delete the unwanted portion
    unset($input_arr[$i]["data"]["field_new"]);
} // for loops ENDS

?>

Assumptions:

• Your base/parent array is numerically indexed.
• In each array, field_new is at same level.

Please add the code you are using you to produce/get this array, and we could provide you more specific answers.
