Print out everything inside array in php
<p>can anyone explain why I can't see what's inside the array? I think it supposed to be able to have multiple numbers (subscriptions) so maybe that's why I'm having trouble? Here's the code. </p>

<pre><code> $num = $_SESSION['subscription_ids'];
 if(is_array($num))
  {
print_r($num);
  }
    else
  {
echo "not an array";
   }

//Thanks DonnieM, yet It's spliting out "Array ( ) " no joke. 
</code></pre>

<p>What is going on?</p>
