foreach with different value results is correct but i got error message

Help me please.

Results from print_r($response->results)

Code:

[13] => stdClass Object ( [id] => 738573 [title] => Operation Finale )
[14] => stdClass Object ( [id] => 442249 [title] => The First Purge )
[15] => stdClass Object ( [id] => 79696 [name] => Manifest )

my view

Code:

<? foreach ($response->results as $v){
    $retVal = ($v->title) ? $v->title : $v->name ;
    echo $retval;
<? } ?>

If i use code above, results is correct but i get error message: Undefined property: stdClass::$title.
i know that is uncorrect because foreach for array [15] is false (not results).

how i can fix it.
