Why not use union operator

$a = array(0=>'x', 3=>'y');
$b = array(0=>'s', 1=>'k',  2=>'m', 3=>'z');

// union of array $a and $b
$c = $a + $b;
// sort array by key, so output keys are sorted
ksort($c);
echo '<pre>' . print_r($c, true) . '</pre>';

OUTPUT

Array
(
    [0] => x
    [1] => k
    [2] => m
    [3] => y
)

You may use array_replace as the other users have suggested.

OR

<?php
$a=array(0=>'x',3=>'y');
$b=array(0=>'s',1=>'k',2=>'m',3=>'z');
$c=$a+$b;
ksort($c);
print_r($c);
?>

Use array_replace - Replaces elements from passed arrays into the first array

<?php
  $a=array(0=>'P',3=>'R');
  $b=array(0=>'s',1=>'k',2=>'m',3=>'z');
  print_r(array_replace($a1,$a2));
?>

Make use of array_replace()

<?php
$a=array(0=>'x',3=>'y');
$b=array(0=>'s',1=>'k',2=>'m',3=>'z');
print_r(array_replace($b,$a));

OUTPUT :

Array
(
    [0] => x
    [1] => k
    [2] => m
    [3] => y
)
