[1] pclose( popen( $cmdln, 'r' ) );
--------------------------------------------------------------
test-pc worked with popen.

* Make sure php in the enviroment path
* Reboot Windows

==============================================================
[2] deamon method
--------------------------------------------------------------
deamon failed.
deamon is batch file that starts a php scirpt keeps monitoring
a drop folder to see if anyone drops a command file. If any,
then it picks it up and run it using pclose( popen( $txt, 'r' ) ).

It works for the first run but in the second run,
it gets an error message, "it's alredy run by another process"
==============================================================
[3] curl method
--------------------------------------------------------------
curl method seems to work but it's still web server's process.
It's preferable to hava a stand along process that pops up
in a desktop like [1]
