Description:
------------
Ref: https://www.php.net/manual/en/install.windows.manual.php

Script fails as written. The cause is:
set phpdir=c:\php
set phppath=php-5.6.19-nts-Win32-VC11-x86

used as: '%phpdir%\%phppath%\php-cgi.exe' in several lines when phppath is empty, i.e. set 'phppath='.

The test script below corrects this, and has some added remarks.
