title: How do I continue the execution when exec(sleep NUMBER; anotherCommand) in PHP?
body: <p>I have this code: </p>
  
  <pre><code>&lt;?php
      exec("sleep 15m; ls -l");
      echo "Done";
  ?&gt;
  </code></pre>
  
  <p>But it gets stuck and won't stop loading until 15 minutes have passed, is there anyway to not wait for the exec execution?</p>
