Symfony execution of long running script

I am using Symfony2 and I want to run a long script written in C++ (for example 60 minutes).

Now I do it via shell_exec():

$pid = shell_exec('nohup my/program/written/in/c++.out some arguments > /dev/null 2>/dev/null & echo $!');

If I keep refreshing a page the script runs fine, but if I go AFK the script is terminated with process of PHP server (/usr/bin/php-cgi).

Is there a way to isolate C++ program from PHP server process? With nohup the process has ppid = 1, so it should be isolated, but it is not.

Solution

  • You can look at the Symfony Process Component : http://symfony.com/doc/current/components/process.html

    $process = new Process('nohup my/program/written/in/c++.out some arguments');
$process->run();

    You will be able to run your process.
