Do I have a chance to find the pid of the application I'm running with popen?
I know it's possible with proc_open but it's unlikely for me to change my app's structure
Or how can I stop the process that is opened with popen and continues to run?
When encoding stream with ffmpeg sometimes I need to stop
function popen: https://www.php.net/manual/en/function.popen.php
function pclose: https://www.php.net/manual/en/function.pclose.php
Where pclose will return -1 if it could not close the process.
If pclose cannot close the process run popen & use a system command to kill the process by getting the parent pid of the forked process:
Killing processes opened with popen()?
Very last answer may work, otherwise use proc_open:
