comparing array indexes or multi-dimentional array rows php

Question

I have 2 arrays to compare their indexes, how can i compare them by checking the empty indexes of first array and if so, then change the value of second array of same index.

it can be solved as 2D array by comparing the rows indexes.

array (size=5)
  0 => string '' (length=0)
  1 => string '10' (length=6)
  2 => string '' (length=0)
  3 => string '11' (length=3)
  4 => string '' (length=0)
array (size=5)
  0 => string '1' (length=4)
  1 => string '2' (length=11)
  2 => string '3' (length=11)
  3 => string '4' (length=11)
  4 => string '5' (length=10)

For instance, index 0 of first array is empty, so index 0 of second array incremented by 1. and so on

try this

 <?php
      $a=array('',10,11,'');
      $b=array(1,2,3,4,5);

      foreach($a as $k=>$v){
        if($v==''){

         $b[$k]=++$b[$k] ;
        }

        }

      print_r($b);

    ?>

output

Array ( [0] => 2 [1] => 2 [2] => 3 [3] => 5 [4] => 5 )
