I've just start working on symfony framwork and having a problem.
(I'm working on Windows XP, and xampp installed.)

I've start working with symfony sandbox, and i've installed symfony framwork successfully.

In a dcoument it was wirtten that to execute the following command from command prompt:

> php symfony propel-build-model:

Make sure to be at the root of your project (sf_sandbox/) when you call the symfony command.

but when i execute the command i got the error message:
php is not recognized as an internal or external command.

I think i've to add the environment variables for PHP but how,
and if is there any other mistake i'm doing please guide me.

Thank you.
