title: Simple PHP code not working
body: <p>I am new to PHP and following some online training. I entered the following code and it doesn't seem to be working.  I checked the syntax with the instructors video several times, but can't find any differences.  The only thing I added (after the echos were not working) is the print_r command to see if the array was even being recognized.</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
      &lt;title&gt;Array Functions&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
      &lt;?php $array1 = array(4,8,15,16,23,42); ?&gt;
  
      Count: &lt;?php echo count($array1); ?&gt;&lt;br /&gt;
      Max Value: &lt;?php echo max($array1); ?&gt;&lt;br /&gt;
      Min Value: &lt;?php echo min($array1); ?&gt;&lt;br /&gt;
      &lt;pre&gt;&lt;?php print_r($array1); ?&gt;&lt;/pre&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>The result I am getting is:</p>
  
  <p>Count:<br>
    Max Value:<br>
    Min Value:   </p>
  
  <p>The values are not appearing. Since the text is returning, it seems that WAMP and Firefox are working and the correct file is being accessed.  What else could make my data not be appearing?</p>
