Array unserialize issue returning null/false

I've got an array being returned in this format:

a:1:{i:0;i:305;}

I can't seem to unserialize() it to access the 305. Anyone have an idea on what I can do?

Query in WordPress:

$order_id = $wpdb->get_row("SELECT meta_value FROM wp_postmeta WHERE post_id=" . $t->object_id . " AND meta_key='wpc_inv_order_id");

I attempted to use:

$str = $order_id->meta_value;
$a = unserialize($str);
var_dump($a);
echo $a;

which resulted in bool(false).

However, it appears that by just doing echo $order_id->meta_value; it somehow unserialized itself and is now giving me the ID value in the serialized array.

So by doing:

$str = $order_id->meta_value;
echo $str;

I'm getting output 305 on the above.

Thank you for your help!

Looking what is result of unserialize

$str = 'a:1:{i:0;i:305;}';
var_dump($a = unserialize($str));

array(1) {
  [0]=>
  int(305)
}

So take it by$a[0];
