Code snippet is actually a JSON, do you work with JSON or with php array? — Lukáš Irsák

Do simply with json_decode(), Also your json string is missing starting and ending curly braces i.e { }

$array = json_decode($object,1);
foreach($array['active_joins2'] as $key=>$value){
    echo $value['paper']['sample_url'].PHP_EOL;
}

I think this is json, you can use json_decode function and after that use that in php like array or std object json_decode
