A foreach loop would do. If your actual array has strings for keys, not =
=

integers, another approach is this:

<?php
$array1 =3D array('a' =3D> 'foo', 'd' =3D> 'bar','y' =3D> 'not valid');
$array2 =3D array('a' =3D> 'x','b' =3D> 'foz','c' =3D> 'baz','d' =3D> 'x=
');

$rows_to_insert =3D array_intersect_key($array1,$array2);
$merged =3D array_merge($array2,$rows_to_insert);
print_r($merged);
?>
-- =
