Just use array_replace_recursive:

$finalArr = array_replace_recursive($arr1,$arr2);

There is a similar thread. And more such questions in SO.

Thanks It works with just an update, and that is convert both the stdClass Objects to an array by using $arr1 = json_decode(json_encode($arr1), true); $arr2 = json_decode(json_encode($arr2), true); AND finally use $finalArr = array_replace_recursive($arr1,$arr2);

The array_replace_recursive() function not working when the first and second both array has unique values, it is not adding both records.

Then go for array_merge_recursive in that case

OK, now i got multiple records against the same [Author] how to group them in a single record within the same array, Thanks.
