title: How to run a php script in the background in another php script (like an update button)
body: <p>How would I go about running a php script when I pressed say an "update" button, in which then it would run say script x1.php (which has no echo's or or other output, successes or failed) then update the current page (I know the update part can be done with ajax, but im not sure how and how I would get the x1.php script to run in the background and trigger the ajax update when done).</p>
  
  <p>Any pointers in the right direction would be great :)</p>
