[RESOLVED] 'php' is not internal or external command.....

Hi All,

If I run php -v command to know php version on command line,
it shows error like
'php' is not recognized as an internal or external command, operable program or batch file'

what does this error means?
I'm using xampp server on windows

The directory in which PHP is installed is not included in your PATH variable. You can add directories to environment variables using the System control panel. (Start | Control Panel | System | Advanced | Environment Variables)

Thanks Penagate!!!! solved :)
