How to fill a empty value in KEY=> VALUE for array_combine in php

I wish to make Key and Value combining with 2 arrays, but both arrays are not equal.

$array1 = array("1","2","3","4","5");
$array2 = array("apple","banana","","dog","");
$key_value = array_combine($array1,$array2);

The output is:

array_combine(): Both parameters should have an equal number of elements

But I need to below output be like

print_r($key_value);
array(5) { 
          [1]=> string(5) "apple" 
          [2]=> string(6) "banana" 
          [3]=> string(8) "No Value" 
          [4]=> string(3) "dog" 
          [5]=> string(8) "No Value" 
         }

How can do this if null, insert "no value" text.

use array_map() and array_combine()

<?php

$array1 = array("1","2","3","4","5");
$array2 = array("apple","banana","","dog","");

 $array2 = array_map(function($v){
        return (empty($v)) ? "No Value" : $v;
    },$array2);

$key_value = array_combine($array1,$array2);
print_r($key_value);
