How do I get the value in this object?
<p>I feel silly for asking, but how do I get <code>plan</code> value in this object? <code>_object</code> is protected, so PHP telling me I cannot. I am using the PHP library for Recurly.</p>

<pre><code>object(Recurly_SubscriptionList)#47 (7) {
  ["_etag":"Recurly_Pager":private]=&gt; NULL
  ["_position":"Recurly_Pager":private]=&gt;int(0)
  ["_count":"Recurly_Pager":private]=&gt;NULL
  ["_objects":protected]=&gt; array(1) {
    [0]=&gt; object(Recurly_Subscription)#50 (6) {
      ["_values":protected]=&gt; array(11) {
        ["subscription_add_ons"]=&gt; array(0) {}
        ["account"]=&gt; object(Recurly_Stub)#54 (4) {
          ["objectType"]=&gt; string(7) "account"
          ["_href":protected]=&gt; string(37) "https://api.recurly.com/v2/accounts/1"
          ["_client":protected]=&gt;NULL
          ["_links":protected]=&gt;array(0) {}
        }
        ["plan"]=&gt; hello
</code></pre>
