  <p>I have used this code for fetching html content from given website of url.</p>
  
  <pre><code>**Code:**
  
  =================================================================
  
  example URL: http://www.qatarsale.com/EnMain.aspx
  
  /*
  
  $regexp = '/&lt;div id="UpdatePanel4"&gt;(.*?)&lt;\/div&gt;/i';
  
  @preg_match_all($regexp, @file_get_contents('http://www.qatarsale.com/EnMain.aspx'), $matches, PREG_SET_ORDER);*/
  
  /*
  </code></pre>
  
  <p>but $matches returns blank array. I want fetch all html content that are found in div id="UpdatePanel4".</p>
  
  <p>If anybody have any solution please suggest me.</p>
