Commenting php tags
<p>I got this code below from a tutorial I'm using to learn PHP.  I know that <code>//</code> is used to comment out code. In the first line of the code below, you see  <code>{// subject selected ?&gt;</code></p>

<p>Is the php tag  <code>?&gt;</code>  not commented out by the <code>//</code> along with the <code>subject selected</code> text?</p>

<pre><code>&lt;?php if (!is_null($sel_subject)) {// subject selected ?&gt;
&lt;h2&gt;&lt;?php echo   $sel_subject['menu_name'];?&gt;&lt;/h2&gt;
&lt;?php } elseif (!is_null($sel_page)) {// page selected ?&gt;
&lt;h2&gt;&lt;?php echo $sel_page['menu_name']; ?&gt;&lt;/h2&gt;
&lt;?php } else { // nothing selected ?&gt;
&lt;h2&gt;Select a subject or page to edit&lt;/h2&gt;
&lt;?php } ?&gt;
</code></pre>
