title: HTML DOM replace Comma with a Dot
body: <p>Im using an HTML DOM this is the code:</p>
  <pre><code>&lt;?php
  include('simple_html_dom.php');
  $html = file_get_html('https://www.funda.nl/beoordelingenwidget/live/16186/3/3%3d33%3b6%3d62/aankoop/');
  echo $html-&gt;find(&quot;.user-reviews-averages-number&quot;, 0);
  ?&gt;
  </code></pre>
  <p>The output is: 9,4 <strong>but i want it to be 9.3</strong></p>
  <p>I tried this:</p>
  <pre><code>&lt;?php
  include('simple_html_dom.php');
  $html = str_replace(',', '.', $html);
  $html = file_get_html('https://www.funda.nl/beoordelingenwidget/live/16186/3/3%3d33%3b6%3d62/aankoop/');
  echo $html-&gt;find(&quot;.user-reviews-averages-number&quot;, 0);
  ?&gt;
  </code></pre>
  <p>But that doesn't work. Can somebody tell me what i need to do?</p>
  <p>Kind regards.</p>
