php.ini

register_argc_argv=On

It's a nice approach. But you tell me why do we need register_argc_argv=On in this case?
I have read this https://www.php.net/manual/en/ini.core.php#ini.register-argc-argv but still don't understand.

I am having issue setting up queue on shared host. Though i setup cron to run queue:work once every minute, this is causing 503 error over time. I need a better approach, that is why i want to try your solution.

I copied your code into my laravel 5.7 app/console/kernel.php but the queue didnt run. I tried to manually run schedule:run on localhost but i got "No scheduled commands are ready to run.". Is there any thing i have done wrong?
