PHP on Windows - check if working in background

Question

I have Windows 10 with xampp installed. Let's assume I have a PHP script, containing

set_time_limit(0);
ignore_user_abort(true);

$counter = 0;

while($counter < 60){
    file_put_contents('runtime_log.txt', $counter." \r\n", FILE_APPEND);
    $counter++;
    sleep(1);
}

I can close the browser window and the script will be still writing output to runtime_log.txt If I wanted to check if it's running in the background on Linux, I would use

ps aux | grep php

How to do the same thing on Windows?

EDIT: I have simplified my question, because I can see that it's been misunderstood.

@vadim_hr I have tried to use it, but it doesn't show any php.exe processes. — Enri, Sep 04 '17 at 18:55
probably process is not php.exe, but apache or similar. what about using this utility https://learn.microsoft.com/en-us/sysinternals/downloads/handle ? you can check if file `runtime_log.txt` is still in use. — vadim_hr, Sep 05 '17 at 07:58

Don't put too much effort, just use the constant PHP_OS as also described here: How to get the OS on which PHP is running?

You can't get that information directly from the process list in Windows, because by default Apache is configured to load PHP as a module (a .DLL) so it will not be listed as a different process when it's running (unless PHP is configured to run as CGI, but nowadays that option is not used anymore).

I think that you can search for that using Process explorer, open it and then search (with the binoculars icon) for opened handles for runtime_log.txt, if the file is opened by PHP an open handle should appear for the httpd (Apache) process (this is method I use for finding the program that prevents me from deleting a file).

Note that you probably need to run Process Explorer elevated (as an administrator) since Apache is running as system service.
