Trouble using sandbox of symfony

I'm new to symfony and I am trying to run a simple command on the command line but I get an error message.

When I try to execute the command:

d:\new_xam\xampp\htdocs\sf_sandbox_1_2\sf_sandbox>symfony propel:build-model "

I get the error:

'php.exe' is not recognized as an internal or external command,operable program or batch file.

Can anybody help me?

From stackoverflow

• This is a fairly common issue on Windows systems for people new to Symfony and/or PHP. It seems to be an issue with the PHP path. See here: http://forum.symfony-project.org/index.php/m/44895/?srch=php.exe+command#msg_44895

  jarus : ive tried to change the path , but the path is fine ,still its giving the same error 'php.exe' is not recognized path set c:\program files\xampp\htdocs\sf_sandbox\

• You should be able to prefix everything with "php"

  So instead of "symfony propel:build-model" you can do "php symfony propel:build-model"

• Can you try to use the real path for PHP?

  i.e.,

  "C:\Program Files\PHP\PHP.exe" symfony propel:build-model
  

  At your Symfony directory.
