Is there a command line php shell available for windows? I looking for something similar to the python shell, that will allow me to open and immediately begin executing code.>
There is php-shell - it is not great, but still way better than php -a. (Also, it is dead simple to install, just run pear install http://jan.kneschke.de/assets/2007/2/17/PHP_Shell-0.3.1.tgz.) There is also phpa-norl, but I haven't tried it.
