JSON sub array - PHP decode

I have a JSON feed and within the feed, there is an array inside the feed, I can output everything above the array correctly.

JSON feed output: http://pastebin.com/pxiFVm1d

Code used to output:

$jsonurl = "LINK to feed";
$json = file_get_contents($jsonurl,0,null,null);
$json_output = json_decode($json);

foreach ( $json_output->results as $results )
{
    echo "{$results->name}.<br />";
}

How do I output the photo_rerence which is part of the array (see pastebin)?

Just to add to what arkascha said, if you want to use it as an array, you will need to add the second param on your json_decode:

$json_output = json_decode($json, TRUE);

Refer to php.net/json_decode for details.

If there's the possibility that there might be multiple photos you could do: 

$json_output = json_decode($json);
foreach ( $json_output->results as $results )
{
    foreach($results->photos as $photo) {
        echo $photo->photo_reference;
    }
}

Or if you only ever want to grab from the first one in the array just do:

$json_output = json_decode($json);
foreach ( $json_output->results as $results )
{
   echo $results->photos[0]->photo_reference;
}

Either you make a "deep pick": $results['photos']['photo_reference'], or take a look at phps array_walk() function which allows you to "search" through the array in a recursive manner.
