PHP Question

Check if specified PID is currently running using PHP - Possible without using ps / etc?

We would like to check if a specified process is currently running via PHP.

We would like to simply supply a PID and see if it is currently executing or not.

Does PHP have an internal function that would give us this information or do we have to parse it out of "ps" output?

If you are on Linux, try this :

if (file_exists( "/proc/$pid" )){
    //process with a pid = $pid is running
