title: PHP: Display a "loading" page while a php script is executing
body: <p>Here is what I've got right now...</p>
  
  <p>I have a web page that when accessed, it connects to surveygizmo.com via their open API, retreives a whole lot of data, and then returns that data to me for processing on my end. This process takes roughly 10-12 seconds and while it is executing, the page just sits in the "loading" state and I'm shown a blank white page.</p>
  
  <p>Here is what I want to happen...</p>
  
  <p>When that same web page is accessed, I'd like it to kick off the script execution and begin retrieving the data from surveygizmo.com via their API in the same way I'm doing it now, but while that process is running, I would like there to be a "result are loading" page/message that is shown instead of the blank white page and then once the script execution finishes and all the results have been returned and processed, the "results are loading" page/message disappears.  </p>
  
  <p>I'm pretty familiar with php and javascript, but haven't been able to figure this one out yet.  Any direction or advice on the matter would be greatly appreciated.</p>
  
  <p>Thanks!</p>
