title: Get certain content from a html page
body: <p>When I press 'View source code' of a certain web page, it's kind of like this:</p>
  
  <pre><code>&lt;form action="/WANem/index-advanced.php" method="post"&gt;
  &lt;table border="1" width="100%"&gt;
    &lt;tr&gt;
      &lt;td width="10%" &gt;Delay time(ms) &lt;/td&gt;
      &lt;td width="10%" &gt;&lt;input type="text" name="txtDelay1" size="7" value=1200&gt;
    &lt;/td&gt;
    &lt;input type="submit" value="Apply settings" name="btnApply"&gt;  
  &lt;/table&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>My question is: How can i get '1200' in the code using PHP. 
  I mean i just want to get a certain string in the html code of another website without having to press 'view source code' and copy that string. 
  Thanks for any reply.</p>
