Thanks for your response:

Yes. And easier is php_sapi_name() [or PHP_SAPI], which produces
apache2handler when I'm running php as a web server module. But it
shows me the same thing when php is started from the command line with
either php.exe vs. php-win.exe: cli. If I try try the same thing with
php-cgi, then I get: cgi-fcgi
So that's why the remaining problem is differentiating between php.exe
vs. php-win.exe

phpinfo() shows the PATH environment variable. It does not show the
path to the executable, nor does it show the executable name.

I agree that it probably is. But even under that assumption, how do
you programatically differentiate between php.exe vs. php-win.exe?

Could you elaborate, please - How does this let me determine the called
executable?
