问题
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
$process->run();
Then the process works fine, but I need to wait until the proceess finished in order to render the view.
Any idea what I am doing wrong?
回答1:
I found a workaround to this problem using exec instaed of creating a new Process object.
exec('/usr/bin/php '.$this->get('kernel')->getRootDir().'/console scopusftpupload ' . escapeshellcmd($params) . ' > /dev/null 2>&1 &');

We do our asynchronous processing with Gearman job server - http://gearman.org/
There are bundles that streamlines the use of Gearman in a Symfony project. We use mmoreram/GearmanBundle - https://github.com/mmoreram/GearmanBundle. Basically, you create your worker, which can be a service, and call it for time consuming tasks. We use it for data imports that take long time.
