trigger node js file

Question

I have a JS file that runs via node.js, so normally I crank open a terminal window and type something like node myfile.js and it runs and runs all day; fun.

Assuming you're on Unix-based OS:

You can run shell commands via the exec() function:

// in php file
// to start the script 
exec("node myscript.js &", $output);

$output becomes an array of each line of output, so you can see what the process id is. Then you would use that process id to kill the script:

exec("kill " . $processid);
