Symfony2 - process launching a symfony2 command

Question

My goal is to launch some time consuming functions in the background to avoid user to wait before the server response is rendered.

I have a Symfony project where I am launching an asynchronous process from a controller. This process will launch a Symfony command that will call another controller.

The problem is when I am calling the process with start()

$process = new Process('/usr/bin/php '.$this->get('kernel')->getRootDir().'/console scopusftpupload ' . escapeshellcmd($params));
$process->start();

Then nothing happens with the process, but the redirect and some other code that I have later works.

However, if I do

$process->run();

Then the process works fine, but I need to wait until the proceess finished in order to render the view.

Any idea what I am doing wrong?

Answer 1

I found a workaround to this problem using exec instaed of creating a new Process object.

exec('/usr/bin/php '.$this->get('kernel')->getRootDir().'/console scopusftpupload ' . escapeshellcmd($params) . ' > /dev/null 2>&1 &');
