  • if specify ( must use cronjob format ) , daemon will run it when schedule is reach
• work_count ( optional ) : default to 1 maximum 10, how many script have to run for current task
• timeout (optional) : task timeout in second default is 0 no timeout

To run the script as daemon you can use either init.d or systemd

$connection->set_close_on_destruct(false);
