php is not recognized as an intern command (using windows)

Answer 1

You'll have to add the directory in which the php executable is located to your "path" variable (I guess in your case that would be E:\logiciels\UwAmp\apache\php_5.2.11 ). In Windows, you can do that as described here: http://www.computerhope.com/issues/ch000549.htm

Any directory you place in this path variable (they're separated by a semicolon) will be automatically used in, for example, a cmd shell.

Answer 2

You need to add the path where the binary resides in to the PATH variable. You can do this on XP and Win 7 under the System -> User settings -> User variables
