title: Error in web page "This site cant' be reached"
body: <p>My PHP code:</p>
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang=&quot;en&quot;&gt;
  
  &lt;head&gt;
    &lt;meta charset=&quot;UTF-8&quot;&gt;
    &lt;meta http-equiv=&quot;X-UA-Compatible&quot; content=&quot;IE=edge&quot;&gt;
    &lt;meta name=&quot;viewport&quot; content=&quot;width=device-width, initial-scale=1.0&quot;&gt;
    &lt;title&gt;
      &lt;?php
      echo &quot;this is &quot;;
      echo &quot;title&quot;;
      ?&gt;
    &lt;/title&gt;
  &lt;/head&gt;
  
  &lt;body&gt;
  
  &lt;/body&gt;
  
  &lt;/html&gt;
  </code></pre>
  <p>I am getting</p>
  <blockquote>
  <p>This site can't be reached</p>
  </blockquote>
  <p>In my Chrome browser when I am writing:</p>
  <pre><code>localhost/phpTutorial/comment.php
  </code></pre>
  <p>Here <code>phpTutorial</code> is the folder where all PHP files are stored and PHP tutorial is made inside <code>htdocs</code> of <code>XAMPP</code> folder.</p>
  <p>Location description:-</p>
  <pre><code>C:-&gt;XAMPP-&gt;htdocs-&gt;phpTutorial-&gt;comment.php  
  </code></pre>
  <p>The same URL/PHP files was running smoothly some time before but now it is not running.</p>
  <p>Please solve my issue and suggest what is wrong in this in a beginner friendly way.</p>
