PHP popen does not execute with "start /B" in Main Server

I am working in a IIS server with php7.3 and My code segment looks like this

<?php fclose(popen("start /B php C:\\mydir\\exec.php", "r")); ?>

Code segment of "exec.php" is given below (actual code executes a long process of joining tables and exporting as a csv file). I need "exec.php" to be run in background without being waiting for its completion.

<?php
   $f = fopen("text" . date("H_i_s") .".txt","w");
   fwrite($f,"test");
   fclose($f);
?>

These segments runs just fine when I remove "start /B", but not with it.

It appears that start /B command solely doesn't not trigger the process.

You could try start /B command > NUL 2>&1

It worked in one of my case without understanding why.
