如何停止在另一个页面中执行php脚本？

Question

I've just learned how to setup and start a web-socket server using Ratchet.

I've learned how to start the script using a command from the terminal and the script keeps running forever.

What I want to know now, is how can I start and stop that script (the web-socket server) using php code, not terminal, So that I can have a button to start and stop the web-socket server whenever I want ?

This question might seem naive, but I don't have a clue on how to this, I am new to Ratchet and web-socket.

If you know the pid, then just use command,

exec("kill -9 $pid");

Otherwise, you can use

exec("pkill $progname"); //To kill a any command with name as $progname

Please refer to this for more such options.
