title: How can I force a PHP script to continue on with a script after calling exec()?
body: <p>I'm using the <code>exec</code> function in PHP to run a command. The command I'm running can often take quite a bit of time and I don't have any need to read it's output. Is there a simple way of telling PHP not to wait for the <code>exec</code> command to finish before moving on with the rest of the script?</p>
