title: Asynchronous method exec in PHP
body: <p>I need to start an asynchronous method call in PHP but have no idea or clue in how to achieve this. The big idea is as follow:</p>
  
  <pre><code>public myfunctionAction() {
      // normal flow
      // execute the asynchronous call (WS)
      // continue normal flow
  }
  </code></pre>
  
  <p>How I do that? Can any provide a simple example just to use as a start point? It's possible to leave the asynchronous call executing on the background and continue the normal flow?</p>
  
  <p>I'm using Symfony 2.6.x as development framework if that helps a little</p>
