PHP what is the best way to execute scripts?

Question

PHP

It is necessary to execute bash scripts in php as root. the option to grant rights to the www-data user is not recommended (tell me why too), how would you implement such scripts?
ps linking via cron is not good. need online output of script results

Answer 1

One process (worker) always hangs in memory and is launched under a user with the necessary rights.
Another script - gives a task for execution through a unix socket and receives output into it during execution, which can be redirected directly to the browser.
If necessary, you can create a queue and "carry on a mail dialogue" through the database between these two scripts.
