Start and Stop a Program

[jargen]

I need a way to start a program and store the PID, then manage to stop it at the users request later.

 

Im not sure how i would go about this. It has to work on Windows,

 

Any help?

Thanks.

Take a look at system() or exec()

Dosent help work out how to get the Process ID and stop it.

PHP doesn't have any way to execute something in the background, which is what you need if you want to launch something then get the PID.  In Linux/Unix you can do this using a simple shell script, such as:

#!/bin/bash

/usr/bin/php -r 'sleep(100);' >/dev/null >&1 &
disown
echo $!

 

And run it:

if (exec('./go.sh', $output, $ret)){
   echo 'Launch successful.  Pid='.$output[0];
}
else {
   echo 'Launch failed';
}

 

For windows, running in PHP would be essentially the same but you would have to find or create a program to use as an intermediary which will launch the program you want in the background, then output it's PID.

I don't suppose this thing you're running has a daemon mode, right?
