Question

I have a php scrip, in which i have written the following code

$client = new \Predis\Client();
$client->select(4);
$client->lpush('emailid',$x['to']);


$command = "/usr/bin/php5 -f /var/www/Symfony/src/Ens/NewBundle/Controller/cron.php";

exec( "$command > /dev/null &", $arrOutput );

return $this->render('EnsNewBundle:Email:header.html.twig');

in this I have written an another php script named as cron.php. I want to run that script in background. and I want to check that is this running in background or not. how can i check that

Answer 1

You can take the output of cron in a file by > filename and check if it really runs.

Or check in process list if there is a new php process stating when you run this one.

You should also look at Codememe bundle here

Do check open source queuing systems too, they are helpful many times.
Like Beanstalkd or RabbitMQ

You can push data to these queues, they can be say “filenames” and other worker takes data from the “tubes” of queues and apply say “php filename” and then picks up next data from queue.
