title: execute PHP MYSQL in the background
body: <p>Is it possible, on a website/webserver (having full root access) to run a PHP script which calls mysql queries in the background. What I mean with that: </p>
  
  <p>An user clicks to process something - however to prevent the user waiting for running the query it should look like it is done for the user - he doesn't has to wait for the PHP/MYSQL in the browser
  However the script should be running on the server and finish </p>
  
  <p>How can I do that? If there is none effective solution in PHP - is it possible with other languages? </p>
  
  <p>I'm not talking about cron jobs - I'm on a ubuntu machine (no windows)</p>
  
  <p>Would be for running many PHP scripts (all the same) in the background - Nginx be the better solution or Apache? Is it even relevant?</p>
