How to run a background process in symfony

Question

I have a symfony commad that needes few minutes to be completed. And i want to run it by a http request. The problem is that the server kills the command process just after sending response, he has a timeout.

i tried to use symfony process asynchronously But still not working ( i get always the timeout problem).

I dont want use the kernel.terminate event, since it is not a best practice. Here is the code in my controller :

            $commandProcess=new Process('php  bin/console app:doSomeThing');
            $commandProcess->setWorkingDirectory('./../');
            $commandProcess->start();
            $commandProcess->setTimeout(50000000);

Any response will be much appreciated.

Thanks for your responses. @Med, i tried before starting the process, but still not work. — Cheikh HAIBALA

"I dont want use the kernel.terminate event, since it is not a best practice" Can you tell us why exactly? — gp_sflover

Why you think it is a timeout problem? Can you show an output? Did you tried to use /usr/local/bin/php /var/www/project/bin/console command instead php bin/console command? php executable can be found using PhpExecutableFinder component. — Evgeny Ruban

I had to desibale the process output and add '&' after the command Here the answer:

     new Process('php  bin/console app:dosomthing &');

    $commandProcess=new Process('php  bin/console app:dosomthing &');
    $commandProcess->setWorkingDirectory('./../');
    $commandProcess->disableOutput();
    $commandProcess->setTimeout(1800);
    $commandProcess->start();

I write here the solution that has finally worked for me

First create a service:

use Symfony\Component\Process\Process;
use Symfony\Component\HttpKernel\KernelInterface;


class ProcessService {

public function __construct(
    private KernelInterface $appKernel
){ }

public function executeProcessAsync($processToExecute) {
    $rootDir = $this->appKernel->getProjectDir();
    $process = Process::fromShellCommandline($processToExecute . ' &');
    $process->setWorkingDirectory($rootDir);
    $process->disableOutput();
    $process->setTimeout(0);
    $process->start();
}

}

Then we use the service from a controller:

class MyController {

public function __construct(
    private ProcessService $procesService
){
public function __invoke(Request $request)
{
// (other stuff ...)

    $this->procesService->executeProcessAsync('php bin/console mycommands:command ');

    // (other stuff...)

}
}
