Can I load lots of data only once and use it on each request?
<p>Is there a way to load a big data object into the memory, which usually has to be loaded at each request, only once?</p>

<p>In Java you can instantiate an object in a servlet when this servlet is loaded, but once it's there you can use it in any request. Example is below. Can this be done in PHP?</p>

<pre><code>public class SampleServlet extends HttpServlet {  
  private static HugeGraphObject hgo;

  public void init() {
    hgo = HugeGraphObjectFactory.get();
  }

  protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    String param = request.getParameter("q");
    response.getWriter().write(hgo.getSomeThing(param));
  }
}
</code></pre>
