First of all, you should strip unnecessary information from your
postings - in your case the content of $myObj and the output are the
only necessary information.

#v+
$a = array();
$b = array();
$a[] = ['contact_details' => ['y' => 'z']];
$b[] = ['billing_details' => ['y' => 'z']];
$c = array_merge($a, $b);
var_dump(json_encode($c));
#v-

string(59) "[{"contact_details":{"y":"z"}},{"billing_details":{"y":"z"}}]"


#v+
$a = ['contact_details' => ['y' => 'z']];
$b = ['billing_details' => ['y' => 'z']];
$c = array_merge($a, $b);
var_dump(json_encode($c));
#v-

string(55) "{"contact_details":{"y":"z"},"billing_details":{"y":"z"}}"

So there is no need to use reduce() or anything else. You are simply
using one (non-associative) level of arrays too much. This would be
easier to debug if you add a print_r($myObj); to your debugging
output.


Personally I'd prefer another version without the irritating
array_merge for better readability, but this is just a matter of
taste producing the same array and the same output:

#v+
$a = ['y' => 'z'];
$b = ['y' => 'z'];
$c = ['contact_details' => $a, 'billing_details' => $b];
var_dump(json_encode($c));
#v-
