What does "1" mean at the end of a php print_r statement?
<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>
