Running PHP via CLI

Kim

I made a php script with a HTML form (POST) which takes many options
and based on the options, it connects to a database file and create
some files from the results. This works fine when using a browser.

Now, I am being asked if it can run via CLI. My first reaction was
"no", but that was before I even had looked into the matter.
Running via CLI is preferred instead of having to install a webserver
solution like WAMP. Also, the target machine which should run the PHP
script is a standalone (no network of any kind).

After reading some about PHP in CLI mode, and experiments have I come
to this conclusion:
* php.exe does not support GET, POST or HTML codes (it will displayed
as raw text)
* php-cgi.exe does support GET but still not POST or HTML codes.
This means you can parse parameters to your php script, like: <php-cgi
path> -n -f <php script> para1=value1 para2=value2 etc. Full access to
$_GET.

I still have not found a way to run this script via CLI.

Do I need to re-write the whole thing specially for CLI mode ?
Is there another way to parse parameters via CLI mode ?
