The simpler way to run a PHP script in background is with exec or shell_exec

You can run following function in a php file which is called via ajax, passing the path of your current script with a log path if you want to store log info: 

shell_exec("/path/to/php /path/to/queue_job.php > /path_to_log/debug.log 2>&1");

  • shell_exec("/path/to/php /path/to/queue_job.php 'alert' > in this case path in which? – JD Savaj Dec 09 '19 at 07:52
  • which path you're asking about? all must be absolute path (not URL) in above command. – prashant Dec 09 '19 at 08:03
  • you can get absolute paths of your php files as mentioned: https://stackoverflow.com/questions/11604445/php-absolute-path-to-root – prashant Dec 09 '19 at 08:04

It can only be done using async task in your PHP part.

  • Assign an ID for every task
  • Your ajax will create new task or fetch the status of existing task
