    // You should double check everything because this delicious function is broken
    if (is_array($data) && isset($data[ 0 ]) &&
        $data[ 0 ] instanceof stdClass  && isset($data[ 0 ]->total_posts)) {
        return $data[ 0 ]->total_posts;
    } else {
        return 0;
    }

Before using $data as array:

$data = (array) $data;

And then simply get your total_posts value from array.

$data[0]['total_posts']

function deliciousCount($domain_name)
{
    $data = json_decode(
        file_get_contents(
            "http://feeds.delicious.com/v2/json/urlinfo/data?url=$domain_name"
        )
    );
    if ($data) {
        return $data->total_posts;
    } else {
        return 0;
    }
}

$delic = deliciousCount($domain_name);

or 

function deliciousCount($domain_name)
{
    $data = json_decode(
        file_get_contents(
            "http://feeds.delicious.com/v2/json/urlinfo/data?url=$domain_name",true
        )
    );
    if ($data) {
        return $data['total_posts'];
    } else {
        return 0;
    }
}

$delic = deliciousCount($domain_name);

According to the manual, there is an optional second boolean param which specifies whether the returned object should be converted to an associative array (default is false). If you want access it as an array then just pass true as the second param.

$data = json_decode(
    file_get_contents(
        "http://feeds.delicious.com/v2/json/urlinfo/data?url=$domain_name"
    ),
    true
);

json_decode returns an instance of stdClass, which you can't access like you would access an array. json_decode does have the possibility to return an array, by passing true as a second parameter.
