title: Call PHP function from jQuery?
body: <p>I have a PHP function on my site which takes a couple of seconds to complete. This holds the whole page up which I don't want.</p>
  
  <p>Would it be possible with jquery to call this PHP function after the page has loaded and display the results in a div? Also to display an ajax loader image until the PHP function has completed?</p>
  
  <p>I've been looking at jQuery.post but can't seem to get it to work.</p>
  
  <p>Would someone be able to help?</p>
  
  <p>Thank you</p>
