title: What does "1" mean at the end of a php print_r statement?
body: <p>My <code>print_r($view)</code> function yields:</p>
  
  <pre><code>View Object
  (
      [viewArray:View:private] =&gt; Array
          (
              [title] =&gt; Projet JDelage
          )
  )
  1 &lt;--------------
  </code></pre>
  
  <p>What does the "1" at the end mean? The PHP manual isn't very clear on how to parse the output of <code>print_r</code>.</p>
