Purpose of this script is to provide visual feedback to show something is happening.

Add '''/b''' to start as shown below this runs a script in the background

   $cmd = 'start /b usr\local\php\php.exe -n test_2.php';

Run the batch file (double click on Run.bat).

Edit file test_1.php

There are two changes, remove the '''/b''' and replace '''php.exe''' with '''php-win.exe''' this runs a script in the background  

   usleep(2000000);

   pclose(popen($cmd,'r'));    // Start a new forked process close file pointer

exit(0); // Script ran OK

Run the batch file (double click on Run.bat). The second script is run in the background, after a delay (about ten seconds) '''test_3.php''' is displayed as expected.
